(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information and amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC(1), and in particular Articles 4(3), 5(4) and 6(2) and Article 12 thereof,

Having regard to Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive)(2), and in particular Article 39(7) thereof,

Whereas:

(1) Regulation (EC) No 595/2009 is one of the separate regulatory acts under the type-approval procedure laid down by Directive 2007/46/EC.

(2) Regulation (EC) No 595/2009 requires new heavy duty vehicles and engines to comply with new emission limits and introduces additional requirements on access to information. The technical requirements will apply from 31 December 2012 for new types of vehicles and from 31 December 2013 for all new vehicles. The specific technical provisions necessary to implement Regulation (EC) No 595/2009 should be adopted. Therefore, the present Regulation aims at setting the requirements necessary for the type-approval of Euro VI specification vehicles and engines.

(3) Article 5(4) of Regulation (EC) No 595/2009 requires the Commission to adopt implementing legislation setting out specific technical requirements relating to the control of emissions from vehicles. Therefore, it is appropriate to adopt those requirements.

(4) Following the adoption of the main requirements for type-approval of heavy duty motor vehicles and engines by Regulation (EC) No 595/2009, it is necessary to establish administrative provisions for that EC type-approval. Those administrative requirements should include provisions for conformity of production and in-service conformity to ensure continued good performance of production vehicles and engines.

(5) In accordance with Article 6 of Regulation (EC) No 595/2009, it is also necessary to establish requirements to ensure that vehicle on-board diagnostic (hereinafter ‘OBD’) and vehicle repair and maintenance information is readily accessible, so as to ensure that independent operators have access to such information.

(6) In accordance with Regulation (EC) No 595/2009, the measures provided for in this Regulation regarding access to vehicle repair and maintenance information, information for diagnostic tools and the compatibility of replacement parts with vehicle OBD systems, should not be restricted to emission-related components and systems but cover all aspects of a vehicle subject to type-approval within the scope of this Regulation.

(7) In accordance with Article 5 of Regulation (EC) No 595/2009, the Commission should adopt measures for implementing the use of portable measurement systems for verifying the actual in-use emissions and verifying and limiting the off-cycle emissions. It is therefore necessary to set out, within an appropriate timeframe, provisions on off-cycle emissions both at type-approval and for verifying and limiting the off-cycle emissions in actual use of the vehicles. For the purpose of in-service conformity a procedure using portable emissions measurement systems (hereinafter ‘PEMS’) should be introduced. The PEMS procedures introduced through this Regulation should be subject to an assessment on the basis of which the Commission should be empowered to amend the in-use provisions.

(8) In accordance with Article 5(4)(d) of Regulation (EC) No 595/2009, it is necessary to establish requirements for type-approval of replacement pollution control devices so as to ensure that they function correctly.

(9) In accordance with Article 5(4)(d) of Regulation (EC) No 595/2009, it is necessary to establish requirements for determining deterioration factors to be used for verifying the durability of engine systems. In addition and subject to the results of research and development on methods for bench ageing of engine systems the Commission should be empowered to amend the provisions for determining deterioration factors.

(10) As provided for by Article 12(1) of Regulation (EC) No 595/2009, new limit values and a measurement procedure for the number of particles emitted should be introduced. The measurement procedure should be based on the work of the Particulate Measurement Programme (PMP) of the United Nations Economic Commission for Europe (hereinafter ‘UN/ECE’).

(11) In accordance with Article 12(2) of Regulation (EC) No 595/2009, limit values for the World Harmonized Transient Driving Cycle (hereinafter ‘WHTC’) and the Worldwide Harmonised Steady state Cycle (hereinafter ‘WHSC’) as specified in Annex 4B to Regulation No 49 of the Economic Commission for Europe of the United Nations (UN/ECE) — Uniform provisions concerning the measures to be taken against the emission of gaseous and particulate pollutants from compression-ignition engines for use in vehicles, and the emission of gaseous pollutants from positive-ignition engines fuelled with natural gas or liquefied petroleum gas for use in vehicles(3) should be introduced.

(12) The Commission should assess the need for specific measures regarding multi-setting engines, and should be empowered to amend the provisions in accordance with the results of that assessment.

(13) Regulation (EC) No 595/2009 and Directive 2007/46/EC should therefore be amended accordingly.

(14) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles,

ADMINISTRATIVE PROVISIONS FOR EC TYPE-APPROVAL

1. REQUIREMENTS ON FUEL RANGE

1.1. Requirements on universal fuel range type-approval

A universal fuel range approval shall be granted subject to the requirements specified in points 1.1.1 to 1.1.6.1.

1.1.1.

The parent engine shall meet the requirements of this Regulation on the appropriate reference fuels specified in Annex IX. Specific requirements shall apply to natural gas fuelled engines, as laid down in point 1.1.3.

1.1.2.

If the manufacturer permits to operate the engine family to run on market fuels not included in Directive 98/70/EC of the European Parliament and of the Council(1) and the EN 228 CEN standards in the case of unleaded petrol and EN 590 CEN standard in the case of diesel, such as running on B100, the manufacturer shall, in addition to the requirements in point 1.1.1:

(a) declare the fuels the engine family is capable to run on in point 3.2.2.2.1 of Part 1 of Appendix 4;

(b) demonstrate the capability of the parent engine to meet the requirements of this Regulation on the fuels declared;

(c) be liable to meet the requirements of in-service conformity specified in Annex II on the fuels declared including any blend between the declared fuels and the market fuels included in Directive 98/70/EC and the relevant CEN standards.

1.1.3.

In the case of a natural gas fuelled engine the manufacturer shall demonstrate the parent engines capability to adapt to any fuel composition that may occur on the market within the European Union.

In the case of natural gas there are generally two types of fuel, high calorific fuel (H-gas) and low calorific fuel (L-gas), but with a significant spread within both ranges; they differ significantly in their energy content expressed by the Wobbe Index and in their λ-shift factor (S

). Natural gases with a λ-shift factor between 0,89 and 1,08 (0,89 ≤ S

≤ 1,08) are considered to belong to H-range, while natural gases with a λ-shift factor between 1,08 and 1,19 (1,08 ≤ S

≤ 1,19) are considered to belong to L-range. The composition of the reference fuels reflects the extreme variations of S

The parent engine shall meet the requirements of this Regulation on the reference fuels G

(fuel 1) and G

(fuel 2), as specified in Annex IX, without any readjustment to the fuelling between the two tests. One adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After the adaptation run the engine shall be cooled down in accordance with Section 7.6.1 of Annex 4B to UN/ECE Regulation No 49.

1.1.3.1.

At the manufacturer's request the engine may be tested on a third fuel (fuel 3) if the λ-shift factor (S

) lies between 0,89 (that is the lower range of G

) and 1,19 (that is the upper range of G

), for example when fuel 3 is a market fuel. The results of this test may be used as a basis for the evaluation of the conformity of the production.

1.1.4.

In the case of an engine fuelled with natural gas which is self adaptive for the range of H-gases on the one hand and the range of L-gases on the other hand, and which switches between the H-range and the L-range by means of a switch, the parent engine shall be tested on the relevant reference fuel as specified in Annex IX for each range, at each position of the switch. The fuels are G

(fuel 1) and G

(fuel 3) for the H-range of gases and G

(fuel 2) and G

(fuel 3) for the L-range of gases. The parent engine shall meet the requirements of this Regulation at both positions of the switch without any readjustment to the fuelling between the two tests at each position of the switch. One adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After the adaptation run the engine shall be cooled down in accordance with Section 7.6.1 of Annex 4B to UN/ECE Regulation No 49.

1.1.4.1.

At the manufacturer's request the engine may be tested on a third fuel instead of G

(fuel 3) if the λ-shift factor (S

) lies between 0,89 (that is the lower range of G

) and 1,19 (that is the upper range of G

), for example when fuel 3 is a market fuel. The results of this test may be used as a basis for the evaluation of the conformity of the production.

1.1.5.

In the case of natural gas engines, the ratio of the emission results ‘r’ shall be determined for each pollutant as follows:

[Bild bitte in Originalquelle ansehen]

, or

[Bild bitte in Originalquelle ansehen]

, and

[Bild bitte in Originalquelle ansehen]

1.1.6.

In the case of LPG the manufacturer shall demonstrate the parent engines capability to adapt to any fuel composition that may occur across the market.

In the case of LPG there are variations in C

composition. These variations are reflected in the reference fuels. The parent engine shall meet the emission requirements on the reference fuels A and B as specified in Annex IX without any readjustment to the fuelling between the two tests. One adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After the adaptation run the engine shall be cooled down in accordance with Section 7.6.1 of Annex 4B to UN/ECE Regulation No 49.

1.1.6.1.

The ratio of emission results ‘r’ shall be determined for each pollutant as follows:

[Bild bitte in Originalquelle ansehen]

1.2. Requirements on restricted fuel range type-approval in case of positive-ignition engines fuelled with natural gas or LPG

Fuel range restricted approval shall be granted subject to the requirements specified in points 1.2.1 to 1.2.2.3.

1.2.1.

Exhaust emissions type-approval of an engine running on natural gas and laid out for operation on either the range of H-gases or on the range of L-gases.

The parent engine shall be tested on the relevant reference fuel, as specified in Annex IX, for the relevant range. The fuels are G

(fuel 1) and G

(fuel 3) for the H-range of gases and G

(fuel 2) and G

(fuel 3) for the L-range of gases. The parent engine shall meet the requirements of this Regulation without any readjustment to the fuelling between the two tests. One adaptation run over one WHTC hot cycle without measurement is permitted after the change of the fuel. After the adaptation run the engine shall be cooled down in accordance with Section 7.6.1 of Annex 4B to UN/ECE Regulation No 49.

1.2.1.1.

At the manufacturer's request the engine may be tested on a third fuel instead of G

(fuel 3) if the λ-shift factor (S

) lies between 0,89 (that is the lower range of G

) and 1,19 (that is the upper range of G

), for example when fuel 3 is a market fuel. The results of this test may be used as a basis for the evaluation of the conformity of the production.

1.2.1.2.

The ratio of emission results ‘r’ shall be determined for each pollutant as follows:

[Bild bitte in Originalquelle ansehen]

, or

1.2.2.

Exhaust emissions type-approval of an engine running on natural gas or LPG and designed for operation on one specific fuel composition.

The parent engine shall meet the emission requirements on the reference fuels G

and G

in the case of natural gas, or the reference fuels A and B in the case of LPG, as specified in Annex IX. Fine tuning of the fuelling system is allowed between the tests. This fine tuning will consist of a recalibration of the fuelling database, without any alteration to either the basic control strategy or the basic structure of the database. If necessary the exchange of parts that are directly related to the amount of fuel flow such as injector nozzles is allowed.

1.2.2.1.

At the manufacturer's request the engine may be tested on the reference fuels G

and G

, or on the reference fuels G

and G

, in which case the type-approval is only valid for the H-range or the L-range of gases respectively.

1.2.2.2.

On delivery to the customer the engine shall bear a label as specified in Section 3.3 stating for which fuel composition the engine has been calibrated.

2. EXHAUST EMISSIONS TYPE-APPROVAL OF A MEMBER OF A FAMILY

2.1.

With the exception of the case mentioned in point 2.2, the type-approval of a parent engine shall be extended to all family members, without further testing, for any fuel composition within the range for which the parent engine has been approved (in the case of engines described in point 1.2.2) or the same range of fuels (in the case of engines described in either point 1.1 or 1.2) for which the parent engine has been type-approved.

2.2.

If the technical service determines that, with regard to the selected parent engine the submitted application does not fully represent the engine family defined in Part 1 of Appendix 4, an alternative and if necessary an additional reference test engine may be selected by the technical service and tested.

7. CONFORMITY OF PRODUCTION

7.1. General requirements

Measures to ensure conformity of production shall be taken in accordance with Article 12 of Directive 2007/46/EC. Conformity of production shall be checked on the basis of the description in the type-approval certificates set out in Appendix 4 to this Annex. In applying Appendices 1, 2 or 3, the measured emission of the gaseous and particulate pollutants from engines subject to checking for conformity of production shall be adjusted by application of the appropriate deterioration factors (DF’s) for that engine as recorded in the Addendum to the EC type-approval certificate granted in accordance with this Regulation.

The provisions of Annex X to Directive 2007/46/EC shall be applicable where the approval authorities are not satisfied with the auditing procedure of the manufacturer.

All engines subject to tests shall be randomly taken from the series production.

7.2. Emissions of pollutants

7.2.1.

If emissions of pollutants are to be measured and an engine type-approval has had one or more extensions, the tests shall be carried out on the engines described in the information package relating to the relevant extension.

7.2.2.

Conformity of the engine subjected to a pollutant test:

After submission of the engine to the authorities, the manufacturer may not carry out any adjustment to the engines selected.

7.2.2.1.

Three engines shall be taken from the series production of the engines under consideration. Engines shall be subjected to testing on the WHTC, and on the WHSC if applicable, for the checking of the production conformity. The limit values shall be those set out in Annex I to Regulation (EC) No 595/2009.

7.2.2.2.

Where the approval authority is satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 2007/46/EC, the tests shall be carried out according to Appendix 1 to this Annex.

Where the approval authority is not satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 2007/46/EC, the tests shall be carried out according to Appendix 2 to this Annex.

At the manufacturer’s request, the tests may be carried out in accordance with Appendix 3 to this Annex.

7.2.2.3.

On the basis of tests of the engine by sampling as set out in point 7.2.2.2, the series production of the engines under consideration is regarded as conforming where a pass decision is reached for all the pollutants and as non-conforming where a fail decision is reached for one pollutant, in accordance with the test criteria applied in the appropriate Appendix.

When a pass decision has been reached for one pollutant, this decision may not be changed as a consequence of a result from any additional tests made in order to reach a decision for the other pollutants.

If a pass decision is not reached for all the pollutants and if no fail decision is reached for any pollutant, a test is carried out on another engine (see Figure 1).

If no decision is reached, the manufacturer may at any time decide to stop testing. In that case a fail decision is recorded.

Figure 1

7.2.3.

The tests shall be carried out on newly manufactured engines.

7.2.3.1.

At the request of the manufacturer, the tests may be carried out on engines which have been run-in up to a maximum of 125 hours. In this case, the running-in procedure shall be conducted by the manufacturer who shall undertake not to make any adjustments to those engines.

7.2.3.2.

When the manufacturer requests to conduct a running-in procedure in accordance with point 7.2.3.1, it may be carried out on either of the following:

(a) all the engines that are tested;

(b) the first engine tested, with the determination of an evolution coefficient as follows:

(i) the pollutant emissions shall be measured both on the newly manufactured engine and before the maximum of 125 hours set in point 7.2.3.1 on the first engine tested;

(ii) the evolution coefficient of the emissions between the two tests shall be calculated for each pollutant:

Emissions on second test/Emissions first test

The evolution coefficient may have a value less than one.

The subsequent test engines shall not be subjected to the running-in procedure, but their emissions when newly manufactured shall be modified by the evolution coefficient.

In this case, the values to be taken shall be the following:

(a) for the first engine, the values from the second test;

(b) for the other engines, the values when newly manufactured multiplied by the evolution coefficient.

7.2.3.3.

For diesel, ethanol (ED95), petrol, E85 and LPG fuelled engines, all these tests may be conducted with the applicable market fuels. However, at the manufacturer’s request, the reference fuels described in Annex IX may be used. This implies tests, as described in Section 1 of this Annex, with at least two of the reference fuels for each gas engine.

7.2.3.4.

For NG fuelled engines, all these tests may be conducted with market fuel in the following way:

(a) for H marked engines with a market fuel within the H-range (0,89 ≤ Sλ ≤ 1,00);

(b) for L marked engines with a market fuel within the L-range (1,00 ≤ Sλ ≤ 1,19);

However, at the manufacturer’s request, the reference fuels described in Annex IX may be used. This implies tests as described in Section 1 of this Annex.

7.2.3.5.

In the case of dispute caused by the non-compliance of gas fuelled engines when using a market fuel, the tests shall be performed with a reference fuel on which the parent engine has been tested, or with the possible additional fuel 3 as referred to in points 1.1.4.1 and 1.2.1.1 on which the parent engine may have been tested. Then, the result shall be converted by a calculation applying the relevant factors ‘r’, ‘r

’ or ‘r

’ as described in points 1.1.5, 1.1.6.1 and 1.2.1.2. If r, r

or r

is less than 1, no correction shall take place. The measured results and the calculated results shall demonstrate that the engine meets the limit values with all relevant fuels (fuels 1, 2 and, if applicable, fuel 3 in the case of natural gas engines and fuels A and B in the case of LPG engines).

7.2.3.6.

Tests for conformity of production of a gas fuelled engine laid out for operation on one specific fuel composition shall be performed on the fuel for which the engine has been calibrated.

7.3. On-board diagnostics (OBD)

7.3.1.

When the approval authority determines that the quality of production seems unsatisfactory it may request a verification of the conformity of production of the OBD system. Such verification shall be carried out in accordance with the following:

An engine shall be randomly taken from series production and subjected to the tests described in Annex 9B to UN/ECE Regulation No 49. The tests may be carried out on an engine that has been run-in up to a maximum of 125 hours.

7.3.2.

The production is deemed to conform if this engine meets the requirements of the tests described in Annex 9B to UN/ECE Regulation No 49.

7.3.3.

If the engine taken from the series production does not satisfy the requirements of point 7.3.1, a further random sample of four engines shall be taken from the series production and subjected to the tests described in Annex 9B to UN/ECE Regulation No 49. The tests may be carried out on engines that have been run-in up to a maximum of 125 hours.

7.3.4.

The production is deemed to conform if at least three engines out of the further random sample of four engines meet the requirements of the tests described in Annex 9B to UN/ECE Regulation No 49.

7.4. ECU information required for in-service testing

7.4.1.

The availability of the data stream information requested in point 5.2.1 according to the requirements of point 5.2.2 shall be demonstrated by using an external OBD scan-tool as described in Annex X.

7.4.2.

In the case where this information cannot be retrieved in a proper manner while the scan-tool is working properly according to Annex X, the engine shall be considered as non-compliant.

7.4.3.

The conformity of the ECU torque signal with the requirements of points 5.2.2 and 5.2.3 shall be demonstrated by performing the WHSC test according to Annex III.

7.4.4.

In the case where the test equipment does not match the requirements specified in Annex XIV concerning auxiliaries, the measured torque shall be corrected in accordance to the correction method set out in Annex 4B of UN/ECE Regulation No 49.

7.4.5.

The conformity of the ECU torque signal shall be considered sufficient if the calculated torque remains within the tolerances specified in point 5.2.5.

7.4.6.

The availability and conformity checks of the ECU information required for in-service testing shall be performed by the manufacturer on a regular basis on each produced engine type within each produced engine family.

7.4.7.

The results of the manufacturer’s survey shall be made available to the approval authority at its request.

7.4.8.

At the request of the approval authority, the manufacturer shall demonstrate the availability or the conformity of the ECU information in serial production by performing the appropriate testing referred to in points 7.4.1 to 7.4.4 on a sample of engines selected from the same engine type. The sampling rules including sampling size and statistical pass-fail criteria shall be those specified in this Annex for checking the conformity of emissions.

8. DOCUMENTATION

8.1.

The documentation package required by Articles 5, 7 and 9 enabling the approval authority to evaluate the emission control strategies and the systems on-board the vehicle and engine to ensure the correct operation of NO

control measures shall be made available in the two following parts:

(a) the ‘formal documentation package’ that may be made available to interested parties upon request;

(b) the ‘extended documentation package’ that shall remain strictly confidential.

ANNEX II

CONFORMITY OF IN-SERVICE ENGINES OR VEHICLES

1. INTRODUCTION

1.1. This Annex sets out requirements for checking and demonstrating the conformity of in-service engines and vehicles.

2. PROCEDURE FOR IN-SERVICE CONFORMITY

2.1. The conformity of in-service vehicles or engines of an engine family shall be demonstrated by testing vehicles on the road operated over their normal driving patterns, conditions and payloads. The in-service conformity test shall be representative for vehicles operated on their real driving routes, with their normal load and with the usual professional driver of the vehicle. When the vehicle is operated by a driver other than the usual professional driver of the particular vehicle, this alternative driver shall be skilled and trained to operate vehicles of the category subject to be tested.

2.2. If the normal in-service conditions of a particular vehicle are considered to be incompatible with the proper execution of the tests, the manufacturer or the approval authority may request that alternative driving routes and payloads are used.

2.3. The manufacturer shall demonstrate to the approval authority that the chosen vehicle, driving patterns, conditions and payloads are representative for the engine family. The requirements as specified in points 4.1 and 4.5 shall be used to determine whether the driving patterns and payloads are acceptable for in-service conformity testing.

2.4. The manufacturer shall report the schedule and the sampling plan for conformity testing at the time of the initial type-approval of a new engine family.

2.5. Vehicles without a communication interface which permits the collection of the necessary ECU data as specified in points 5.2.1 and 5.2.2 of Annex I, with missing data or with a non-standard data protocol shall be considered as non-compliant.

2.6. Vehicles where the collection of ECU data influences the vehicle emissions or performance shall be considered as non-compliant.

3. ENGINE OR VEHICLE SELECTION

3.1. After the granting of type-approval for an engine family the manufacturer shall perform in-service testing on this engine family within 18 months from first registration of a vehicle fitted with an engine from that family. In case of multistage type-approval first registration means first registration of a completed vehicle.

The testing shall be repeated at least every 2 years for each engine family periodically on vehicles over their useful life period as specified in Article 4 of Regulation (EC) No 595/2009.

At the request of the manufacturer the testing may stop 5 years after the end of production.

3.1.1. With a minimum sample size of three engines the sampling procedure shall be set so that the probability of a lot passing a test with 20 % of the vehicles or engines defective is 0,90 (producer’s risk = 10 %) while the probability of a lot being accepted with 60 % of the vehicles or engines defective is 0,10 (consumer’s risk = 10 %).

3.1.2. The test statistic quantifying the cumulative number of non-conforming tests at the n-th test shall be determined for the sample.

3.1.3. The pass or fail decision of the lot shall be made according to the following requirements:

(a) if the test statistic is less than or equal to the pass decision number for the sample size given in Table 1, a pass decision is reached for the lot;

(b) if the test statistic is greater than or equal to the fail decision number for the sample size given in Table 1, a fail decision is reached for the lot;

(c) otherwise, an additional engine is tested according to this Annex and the calculation procedure is applied to the sample increased by one more unit.

In Table 1 the pass and fail decision numbers are calculated by means of the International Standard ISO 8422/1991.

Table 1

Pass and fail decision numbers of the sampling plan

Minimum sample size: 3

Cumulative number of engines tested (sample size)	Pass decision number	Fail decision number
3	—	3
4	0	4
5	0	4
6	1	4
7	1	4
8	2	4
9	2	4
10	3	4

The approval authority shall approve the selected engines and vehicle configurations before the launch of the testing procedures. The selection shall be performed by presenting to the approval authority the criteria used for the selection of the particular vehicles.

3.2. The engines and vehicles selected shall be used and registered in the Union. The vehicle shall have been in service for at least 25 000 km.

3.3. Each vehicle tested shall have a maintenance record to show that the vehicle has been properly maintained and serviced in accordance with the manufacturer’s recommendations.

3.4. The OBD system shall be checked for proper functioning of the engine. Any malfunction indications and the readiness code in the OBD memory shall be recorded and any required repairs shall be carried out.

Engines presenting a Class C malfunction shall not be forced to be repaired before testing. The Diagnostic Trouble Code (DTC) shall not be cleared.

Engines having one of the counters required by provisions of Annex XIII not at ‘0’ may not be tested. This shall be reported to the approval authority.

3.5. The engine or vehicle shall exhibit no indications of abuse (such as overloading, misfuelling, or other misuse), or other factors (such as tampering) that could affect emission performance. OBD system fault code and engine running hours information stored in the computer shall be taken into account.

3.6. All emission control system components on the vehicle shall be in conformity with those stated in the applicable type-approval documents.

3.7. In agreement with the approval authority, the manufacturer may run in-service conformity testing comprising fewer engines or vehicles than the number given in point 3.1, if the number of engines manufactured within an engine family is less than 500 units per year.

4. TEST CONDITIONS

4.1. Vehicle payload

For the purpose of in-service conformity testing the payload may be reproduced and an artificial load may be used.

In the absence of statistics to demonstrate that the payload is representative for the vehicle, the vehicle payload shall be 50 to 60 % of the maximum vehicle payload.

Appendix 1

Test procedure for vehicle emissions testing with portable emissions measurement systems

1. INTRODUCTION

This Appendix describes the procedure to determine gaseous emissions from on-vehicle on-road measurements using Portable Emissions Measurement Systems (hereinafter ‘PEMS’). The gaseous emissions to be measured from the exhaust of the engine include the following components: carbon monoxide, total hydrocarbons and nitrogen oxides for diesel engines with the addition of methane for gas engines. Additionally, carbon dioxide shall be measured to enable the calculation procedures described in Sections 4 and 5.

2. TEST PROCEDURE

2.1. General requirements

The tests shall be carried out with a PEMS comprised of:

2.1.1.

Gas analysers to measure the concentrations of regulated gaseous pollutants in the exhaust gas.

2.1.3.

A Global Positioning System (hereinafter ‘GPS’).

2.1.4.

Sensors to measure the ambient temperature and pressure.

2.1.5.

A connection with the vehicle ECU).

2.2. Test parameters

The parameters summarised in Table 1 shall be measured and recorded:

2.3. Preparation of the vehicle

The preparation of the vehicle shall include the following:

(a) the check of the OBD system: any identified problems once solved shall be recorded and presented to the approval authority;

(b) the replacement of oil, fuel and reagent, if any.

2.4. Installation of the measuring equipment

2.4.1. Main Unit

Whenever possible, PEMS shall be installed in a location where it will be subject to minimal impact from the following:

(a) ambient temperature changes;

(b) ambient pressure changes;

(d) mechanical shock and vibration;

(e) ambient hydrocarbons — if using a FID analyser that uses ambient air as FID burner air.

The installation shall follow the instructions issued by the PEMS manufacturer.

2.4.2. Exhaust flow meter

The exhaust flow meter shall be attached to the vehicle’s tailpipe. The EFM sensors shall be placed between two pieces of straight tube whose length should be at least 2 times the EFM diameter (upstream and downstream). It is recommended to place the EFM after the vehicle silencer, to limit the effect of exhaust gas pulsations upon the measurement signals.

2.4.3. Global Positioning System

The antenna shall be mounted at the highest possible location, without risking interference with any obstructions encountered during on-road operation.

2.4.4. Connection with the vehicle ECU

A data logger shall be used to record the engine parameters listed in Table 1. This data logger can make use of the Control Area Network (hereinafter ‘CAN’) bus of the vehicle to access the ECU data broadcasted on the CAN according to standard protocols such as SAE J1939, J1708 or ISO 15765-4.

2.4.5. Sampling of gaseous emissions

The sample line shall be heated according to the specifications of point 2.3 of Appendix 2 and properly insulated at the connection points (sample probe and back of the main unit), to avoid the presence of cold spots that could lead to a contamination of the sampling system by condensed hydrocarbons.

The sample probe shall be installed in the exhaust pipe in accordance with the requirements of Section 9.3.10 of Annex 4B to UN/ECE Regulation No 49.

If the length of the sample line is changed, the system transport times shall be verified and if necessary corrected.

2.5. Pre-test procedures

2.5.1. Starting and stabilising the PEMS instruments

The main units shall be warmed up and stabilised according to the instrument manufacturer specifications until pressures, temperatures and flows have reached their operating set points.

2.5.2. Cleaning the sampling system

To prevent system contamination, the sampling lines of the PEMS instruments shall be purged until sampling begins, according to the instrument manufacturer specifications.

2.5.3. Checking and calibrating the analysers

The zero and span calibration and the linearity checks of the analysers shall be performed using calibration gases meeting the requirements of Section 9.3.3 of Annex 4B to UN/ECE Regulation No 49.

2.5.4. Cleaning the EFM

The EFM shall be purged at the pressure transducer connections in accordance with the instrument manufacturer specifications. This procedure shall remove condensation and diesel particulate matter from the pressure lines and the associated flow tube pressure measurement ports.

2.6. Emissions test run

2.6.1. Test start

Emissions sampling, measurement of the exhaust parameters and recording of the engine and ambient data shall start prior to starting the engine. The data evaluation shall start after the coolant temperature has reached 343K (70 °C) for the first time or after the coolant temperature is stabilised within +/– 2K over a period of 5 minutes whichever comes first but no later than 20 minutes after engine start.

2.6.2. Test run

Emission sampling, measurement of the exhaust parameters and recording of the engine and ambient data shall continue throughout the normal in-use operation of the engine. The engine may be stopped and started, but emissions sampling shall continue throughout the entire test.

Periodic checks of the PEMS gas analysers shall be conducted at least every 2 hours. The data recorded during the checks shall be flagged and shall not be used for the emission calculations.

2.6.3. End of test sequence

At the end of the test, sufficient time shall be given to the sampling systems to allow their response times to elapse. The engine may be shut down before or after sampling is stopped.

2.7. Verification of the measurements

2.7.1. Checking of the analysers

The zero, span and linearity checks of the analysers as described in point 2.5.3 shall be performed using calibration gases meeting the requirements of Section 9.3.3 of Annex 4B to UN/ECE Regulation No 49.

2.7.2. Zero drift

Zero response is defined as the mean response, including noise, to a zero gas during a time interval of at least 30 seconds. The drift of the zero response shall be less than 2 % of full scale on the lowest range used.

2.7.3. Span drift

Span response is defined as the mean response, including noise, to a span gas during a time interval of at least 30 seconds. The drift of the span response shall be less than 2 % of full scale on the lowest range used.

2.7.4. Drift verification

This shall apply only if, during the test, no zero drift correction was made.

As soon as practical but no later than 30 minutes after the test is complete the gaseous analyser ranges used shall be zeroed and spanned to check their drift compared to the pre-test results.

The following provisions shall apply for analyser drift:

(a) if the difference between the pre-test and post-test results is less than 2 % as specified in points 2.7.2 and 2.7.3, the measured concentrations may be used uncorrected or may be corrected for drift according to point 2.7.5;

(b) if the difference between the pre-test and post-test results is equal to or greater than 2 % as specified in points 2.7.2 and 2.7.3, the test shall be voided or the measured concentrations shall be corrected for drift according to point 2.7.5.

2.7.5. Drift correction

If drift correction is applied in accordance with point 2.7.4, the corrected concentration value shall be calculated according to Section 8.6.1 of Annex 4B to UN/ECE Regulation No 49.

The difference between the uncorrected and the corrected brake-specific emission values shall be within ± 6 % of the uncorrected brake-specific emission values. If the drift is greater than 6 %, the test shall be voided. If drift correction is applied, only the drift-corrected emission results shall be used when reporting emissions.

3. CALCULATION OF THE EMISSIONS

The final test result shall be rounded in one step to the number of places to the right of the decimal point indicated by the applicable emission standard plus one additional significant figure, in accordance with ASTM E 29-06b. No rounding of intermediate values leading to the final brake-specific emission result shall be allowed.

3.1. Time alignment of data

To minimise the biasing effect of the time lag between the different signals on the calculation of mass emissions, the data relevant for emissions calculation shall be time aligned, as described in points 3.1.1 to 3.1.4.

3.1.1. Gas analysers data

The data from the gas analysers shall be properly aligned using the procedure in Section 9.3.5 of Annex 4B to UN/ECE Regulation No 49.

3.1.2. Gas analysers and EFM data

The data from the gas analysers shall be properly aligned with the data of the EFM using the procedure in point 3.1.4.

3.1.3. PEMS and engine data

The data from the PEMS (gas analysers and EFM) shall be properly aligned with the data from the engine ECU using the procedure in point 3.1.4.

3.1.4. Procedure for improved time-alignment of the PEMS data

The test data listed in Table 1 are split into 3 different categories:

Gas analysers (THC, CO, CO

, NO

concentrations);

Exhaust Flow Meter (Exhaust mass flow and exhaust temperature);

Engine (Torque, speed, temperatures, fuel rate, vehicle speed from ECU).

The time alignment of each category with the other categories shall be verified by finding the highest correlation coefficient between two series of parameters. All the parameters in a category shall be shifted to maximise the correlation factor. The following parameters shall be used to calculate the correlation coefficients:

To time-align:

(a) categories 1 and 2 (Analysers and EFM data) with category 3 (Engine data): the vehicle speed from the GPS and from the ECU;

(b) category 1 with category 2: the CO

concentration and the exhaust mass;

concentration and the engine fuel flow.

3.2. Data consistency checks

3.2.1. Analysers and EFM data

The consistency of the data (exhaust mass flow measured by the EFM and gas concentrations) shall be verified using a correlation between the measured fuel flow from the ECU and the fuel flow calculated using the formula in Section 8.4.1.6 of Annex 4B to UN/ECE Regulation No 49. A linear regression shall be performed for the measured and calculated fuel rate values. The method of least squares shall be used, with the best fit equation having the form:

y = mx + b

where:

— y

is the calculated fuel flow [g/s]

— m

is the slope of the regression line

— x

is the measured fuel flow [g/s]

— b

is the y intercept of the regression line

The slope (m) and the coefficient of determination (r

) shall be calculated for each regression line. It is recommended to perform this analysis in the range from 15 % of the maximum value to the maximum value and at a frequency greater or equal to 1 Hz. For a test to be considered valid, the following two criteria shall be evaluated:

Table 2

Tolerances

Slope of the regression line, m	0,9 to 1,1 — Recommended
Coefficient of determination r2	min. 0,90 — Mandatory

3.2.2. ECU torque data

The consistency of the ECU torque data shall be verified by comparing the maximum ECU torque values at different engine speeds with the corresponding values on the official engine full load torque curve according to Section 5 of Annex II.

3.2.3. Brake-Specific Fuel Consumption

The Brake Specific Fuel Consumption (BSFC) shall be checked using:

(a) the fuel consumption calculated from the emissions data (gas analyser concentrations and exhaust mass flow data), according to the formulae in Section 8.4.1.6 of Annex 4B to UN/ECE Regulation No 49;

(b) the work calculated using the data from the ECU (Engine torque and engine speed).

3.2.4. Odometer

The distance indicated by the vehicle odometer shall be checked against the GPS data and verified.

3.2.5. Ambient pressure

The ambient pressure value shall be checked against the altitude indicated by the GPS data.

3.3. Dry-Wet correction

If the concentration is measured on a dry basis, it shall be converted to a wet basis according to the formula in Section 8.1 of Annex 4B to UN/ECE Regulation No 49.

3.4. NO

x

correction for humidity and temperature

The NO

concentrations measured by the PEMS shall not be corrected for ambient air temperature and humidity.

3.5. Calculation of the instantaneous gaseous emissions

The mass emissions shall be determined as described in Section 8.4.2.3 of Annex 4B to UN/ECE Regulation No 49.

4. DETERMINATION OF EMISSIONS AND CONFORMITY FACTORS

4.1. Averaging window principle

The emissions shall be integrated using a moving averaging window method, based on the reference CO

mass or the reference work. The principle of the calculation is as follows: The mass emissions are not calculated for the complete data set, but for sub-sets of the complete data set, the length of these sub-sets being determined so as to match the engine CO

mass or work measured over the reference laboratory transient cycle. The moving average calculations are conducted with a time increment Δ

equal to the data sampling period. These sub-sets used to average the emissions data are referred to as ‘averaging windows’ in the following Sections.

Any Section of invalidated data shall not be considered for the calculation of the work or CO

mass and the emissions of the averaging window.

The following data shall be considered as invalidated data:

(a) the periodic verification of the instruments and/or after the zero drift verifications;

(b) the data outside the conditions specified in points 4.2 and 4.3 of Annex II.

The mass emissions (mg/window) shall be determined as described in Section 8.4.2.3 of Annex 4B to UN/ECE Regulation No 49.

Appendix 1

Procedure for the measurement of ammonia

1. This Appendix describes the procedure for measurement of ammonia (NH

). For non-linear analysers, the use of linearising circuits shall be permitted.

2. Two measurement principles are specified for NH

measurement and either principle may be used provided it meets the criteria specified in point 2.1 or 2.2, respectively. Gas dryers shall not be permitted for NH

measurement.

2.1. Laser Diode Spectrometer (LDS)

2.1.1. Measurement principle

The LDS employs the single line spectroscopy principle. The NH

absorption line is chosen in the near infrared spectral range and scanned by a single-mode diode laser.

2.1.2. Installation

The analyser shall be installed either directly in the exhaust pipe (in-situ) or within an analyser cabinet using extractive sampling in accordance with the instrument manufacturers instructions. If installed in an analyser cabinet, the sample path (sampling line, pre-filter(s) and valves) shall be made of stainless steel or PTFE and shall be heated to 463 ± 10 K (190 ± 10 °C) in order to minimise NH

losses and sampling artefacts. In addition, the sampling line shall be as short as practically possible.

Influence from exhaust temperature and pressure, installation environment and vibrations on the measurement shall be minimised, or compensation techniques be used.

If applicable, sheath air used in conjunction with in-situ measurement for protection of the instrument, shall not affect the concentration of any exhaust component measured downstream of the device, or sampling of other exhaust components shall be made upstream of the device.

2.1.3. Cross interference

The spectral resolution of the laser shall be within 0,5 cm

-1

in order to minimise cross interference from other gases present in the exhaust gas.

2.2. Fourier Transform Infrared (hereinafter ‘FTIR’) analyser

2.2.1. Measurement principle

The FTIR employs the broad waveband infrared spectroscopy principle. It allows simultaneous measurement of exhaust components whose standardised spectra are available in the instrument. The absorption spectrum (intensity/wavelength) is calculated from the measured interferogram (intensity/time) by means of the Fourier transform method.

2.2.2. Installation and sampling

The FTIR shall be installed in accordance with the instrument manufacturer's instructions. The NH

wavelength shall be selected for evaluation. The sample path (sampling line, pre-filter(s) and valves) shall be made of stainless steel or PTFE and shall be heated to 463 ± 10 K (190 ± 10 °C) in order to minimise NH

losses and sampling artefacts. In addition, the sampling line shall be as short as practically possible.

2.2.3. Cross interference

The spectral resolution of the NH

wavelength shall be within 0,5 cm

-1

in order to minimise cross interference from other gases present in the exhaust gas.

3. EMISSIONS TEST PROCEDURE AND EVALUATION

3.4. Analyser drift

3.4.1 As soon as practical but no later than 30 minutes after the test cycle is complete or during the soak period, the zero and span responses of the analyser shall be determined. The difference between the pre-test and post-test results shall be less than 2 % of full scale.

3.4.2. Determination of analyser drift is not required in the following situations:

(a) if the zero and span drift specified by the instrument manufacturer in points 4.2.3 and 4.2.4 meets the requirements of point 3.4.1;

(b) the time interval for zero and span drift specified by the instrument manufacturer in points 4.2.3 and 4.2.4 exceeds the duration of the test.

3.5. Data evaluation

The average NH

concentration (ppm/test) shall be determined by integrating the instantaneous values over the cycle. The following equation shall be applied:

[Bild bitte in Originalquelle ansehen] in ppm/test)

where:

NH3,i

is the instantaneous NH

concentration in the exhaust gas, ppm,

is the number of measurements.

For the WHTC, the final test result shall be determined with the following equation:

NH3

= (0,14 ×

NH3,cold

) + (0,86 ×

NH3,hot

)

where:

NH3,cold

is the average NH

concentration of the cold start test, ppm,

2. SELECTION OF ENGINES FOR ESTABLISHING USEFUL LIFE DETERIORATION FACTORS

2.1. Engines shall be selected from the engine family defined in accordance with point 6 of Annex I for emission testing in order to establish useful life deterioration factors.

2.2. Engines from different engine families may be further combined into families based on the type of exhaust after-treatment system utilised. In order to place engines with different numbers of cylinders and different cylinder configuration but having the same technical specifications and installation for the exhaust after-treatment systems into the same engine-aftertreatment system family, the manufacturer shall provide data to the approval authority that demonstrates that the emissions reduction performance of such engine systems is similar.

2.3. One engine representing the engine-aftertreatment system family as determined in accordance with point 2.2, shall be selected by the engine manufacturer for testing over the service accumulation schedule defined in point 3.2, and shall be reported to the approval authority before any testing commences.

2.3.1. If the approval authority decides that the worst case emissions of the engine-aftertreatment system family can be characterised better by another engine then the test engine shall be selected jointly by the approval authority and the engine manufacturer.

3. ESTABLISHING USEFUL LIFE DETERIORATION FACTORS

3.1. General

Deterioration factors applicable to an engine-aftertreatment system family are developed from the selected engines based on a service accumulation schedule that includes periodic testing for gaseous and particulate emissions over the WHTC and WHSC tests.

3.2. Service accumulation schedule

Service accumulation schedules may be carried out at the choice of the manufacturer by running a vehicle equipped with the selected engine over an in-service accumulation schedule or by running the selected engine over a dynamometer service accumulation schedule.

3.2.1. In-service and dynamometer service accumulation

3.2.1.1. The manufacturer shall determine the form and extent of the distance, the service accumulation and the ageing cycle for engines, consistent with good engineering practice.

3.2.1.2. The manufacturer shall determine the test points where gaseous and particulate emissions will be measured over the hot WHTC and WHSC tests. The minimum number of test points shall be three, one at the beginning, one approximately in the middle and one at the end of the service accumulation schedule.

3.2.1.3. The emission values at the start point and at the useful life end point calculated in accordance with point 3.5.2 shall meet the limit values specified in the table of Annex I to Regulation (EC) No 595/2009 but individual emission results from the test points may exceed those limit values.

3.2.1.4. At the request of the manufacturer and with the agreement of the approval authority, only one test cycle (either the hot WHTC or WHSC test) needs to be run at each test point, with the other test cycle run only at the beginning and at the end of the service accumulation schedule.

3.2.1.5. Service accumulation schedules may be different for different engine-aftertreatment system families.

3.2.1.6. Service accumulation schedules may be shorter than the useful life period, but shall not be shorter than shown in the table in point 3.2.1.8.

3.2.1.7. For engine dynamometer service accumulation, the manufacturer shall provide the applicable correlation between the service accumulation period (driving distance) and engine dynamometer hours, for example, fuel consumption correlation, vehicle speed versus engine revolutions correlation, etc.

3.2.1.8. Minimum service accumulation period

3.2.1.9. Accelerated ageing is permitted by adjusting the service accumulation schedule on a fuel consumption basis. The adjustment shall be based on the ratio between the typical in-use fuel consumption and the fuel consumption on the ageing cycle, but the fuel consumption on the ageing cycle shall not exceed the typical in-use fuel consumption by more than 30 %.

3.2.1.10. The service accumulation schedule shall be fully described in the application for type-approval and reported to the type-approval authority before the start of any testing.

3.2.2. If the type-approval authority decides that additional measurements need to be carried out on the hot WHTC and WHSC tests between the points selected by the manufacturer it shall notify the manufacturer. The revised service accumulation schedule shall be prepared by the manufacturer and agreed by the approval authority.

3.3. Engine testing

3.3.1. Engine system stabilisation

3.3.1.1. For each engine-aftertreatment system family, the manufacturer shall determine the number of hours of vehicle or engine running after which the operation of the engine-aftertreatment system has stabilised. If requested by the approval authority the manufacturer shall make available the data and analysis used to make this determination. As an alternative, the manufacturer may elect to run the engine between 60 and 125 hours or the equivalent mileage on the ageing cycle to stabilise the engine-aftertreatment system.

3.3.1.2. The end of the stabilisation period determined in point 3.3.1.1 will be deemed to be the start of the service accumulation schedule.

3.3.2. Service accumulation testing

3.3.2.1. After stabilisation, the engine shall be run over the service accumulation schedule selected by the manufacturer, as described in point 3.2. At the periodic intervals in the service accumulation schedule determined by the manufacturer, and, where appropriate, also stipulated by the approval authority according to point 3.2.2 the engine shall be tested for gaseous and particulate emissions over the hot WHTC and WHSC tests. In accordance with point 3.2.1.4, if it has been agreed that only one test cycle (hot WHTC or WHSC) be run at each test point, the other test cycle (hot WHTC or WHSC) shall be run at the beginning and end of the service accumulation schedule.

3.3.2.2. During the service accumulation schedule, maintenance shall be carried out on the engine according to the requirements of point 4.

3.3.2.3. During the service accumulation schedule, unscheduled maintenance on the engine or vehicle may be performed, for example if the OBD system has specifically detected a problem that has resulted in the malfunction indicator (hereinafter ‘MI’) being activated.

3.4. Reporting

3.4.1. The results of all emission tests (hot WHTC and WHSC) conducted during the service accumulation schedule shall be made available to the approval authority. If any emission test is declared to be void, the manufacturer shall provide an explanation of why the test has been declared void. In such a case, another series of emission tests over the hot WHTC and WHSC tests shall be carried out within the following 100 hours of service accumulation.

3.4.2. The manufacturer shall retain records of all information concerning all the emission tests and maintenance carried out on the engine during the service accumulation schedule. This information shall be submitted to the approval authority along with the results of the emission tests conducted over the service accumulation schedule.

3.5. Determination of deterioration factors

3.5.1. For each pollutant measured on the hot WHTC and WHSC tests at each test point during the service accumulation schedule, a ‘best fit’ linear regression analysis shall be made on the basis of all test results. The results of each test for each pollutant shall be expressed to the same number of decimal places as the limit value for that pollutant, as shown in the table of Annex I to Regulation (EC) No 595/2009, plus one additional decimal place. In accordance with point 3.2.1.4 of this Annex, if it has been agreed that only one test cycle (hot WHTC or WHSC) be run at each test point and the other test cycle (hot WHTC or WHSC) run only at the beginning and at the end of the service accumulation schedule, the regression analysis shall be made only on the basis of the test results from the test cycle run at each test point.

At the request of the manufacturer and with the prior approval of the approval authority a non-linear regression shall be permitted.

3.5.2. The emission values for each pollutant at the start of the service accumulation schedule and at the useful life end point that is applicable for the engine under test shall be calculated from the regression equation. If the service accumulation schedule is shorter than the useful life period, the emission values at the useful life end point shall be determined by extrapolation of the regression equation as determined in point 3.5.1.

3.5.3. The deterioration factor for each pollutant is defined as the ratio of the applied emission values at the useful life end point and at the start of the service accumulation schedule (multiplicative deterioration factor).

At the request of the manufacturer and with the prior approval of the approval authority, an additive deterioration factor for each pollutant may be applied. The additive deterioration factor shall be considered as the difference between the calculated emission values at the useful life end point and at the start of the service accumulation schedule.

If the calculation results in a value of less than 1,00 for a multiplicative DF, or less than 0,00 for an additive DF, then the deterioration factor shall be 1,0 or 0,00, respectively.

An example for determination of deterioration factors by using linear regression is shown in Figure 1.

Mixing of multiplicative and additive deterioration factors within one set of pollutants shall not be permitted.

In accordance with point 3.2.1.4, if it has been agreed that only one test cycle (hot WHTC or WHSC) be run at each test point and the other test cycle (hot WHTC or WHSC) run only at the beginning and end of the service accumulation schedule, the deterioration factor calculated for the test cycle that has been run at each test point shall be applicable also for the other test cycle.

2. GENERAL REQUIREMENTS

2.1. In order to receive an extension of an EC type-approval for a vehicle in respect of its engine type approved under this Regulation to a vehicle with a reference mass exceeding 2 380 kg but not exceeding 2 610 kg the manufacturer shall meet the requirements of Annex XII to Commission Regulation (EC) No 692/2008(1) with the exceptions specified below.

Point 1.4.3 of Annex 6 to UN/ECE Regulation 101 referred to in Section 3.3 of Annex XII to Regulation (EC) No 692/2008 shall be understood as:

‘1.4.3.

The fuel consumption, expressed in litres per 100 km (in the case of petrol, LPG, ethanol (E85 and ED95) and diesel) or in m

(a) for vehicles with a positive-ignition engine fuelled with petrol (E10):

FC = (0,120/D) · [(0,831 · HC) + (0,429 · CO) + (0,273 · CO

)]

(b) for vehicles with a positive-ignition engine fuelled with LPG:

norm

= (0,1212/0,538) · [(0,825 · HC) + (0,429 · CO) + (0,273 · CO

)]

If the composition of the fuel used for the test differs from the composition that is assumed for the calculation of the normalised consumption, on the manufacturer’s request a correction factor cf may be applied, as follows:

norm

= (0,1212/0,538) · (cf) · [(0,825 · HC) + (0,429 · CO) + (0,273 · CO

)]

The correction factor cf, which may be applied, is determined as follows:

cf = 0,825 + 0,0693 n

actual

where:

actual

is the actual H/C ratio of the fuel used.

norm

= (0,1336/0,654) · [(0,749 · HC) + (0,429 · CO) + (0,273 · CO

)]

(d) for vehicles with a positive-ignition engine fuelled with ethanol (E85):

FC = (0,1742/D) · [(0,574 · HC) + (0,429 · CO) + (0,273 · CO

)]

(e) for vehicles with a compression-ignition engine fuelled with diesel (B7):

FC = (0,1165/D) · [(0,859 · HC) + (0,429 · CO) + (0,273 · CO

)]

(f) for vehicles with a dedicated compression-ignition engine fuelled with ethanol (ED95):

FC = (0,186/D) · [(0,538 · HC) + (0,429 · CO) + (0,273 · CO

)]

A deteriorated wall-flow DPF is considered as a Qualified Deteriorated Component if, under the operating conditions of the engine specified for the purpose of that test, the pressure drop (delta pressure) across that deteriorated wall-flow DPF exceeds or is no less than 60 % of the pressure drop measured across a clean and non-deteriorated wall-flow DPF of the same type.

2.1.1.1. The manufacturer shall demonstrate that this clean and non-deteriorated wall-flow DPF leads to the same back-pressure as the deteriorated one before its deterioration.

2.1.2. Upon request of the manufacturer, the approval authority may accept per derogation a pressure drop threshold of 50 % instead of 60 %. In order to apply for that derogation, the manufacturer shall justify his request by sound technical arguments, such as the spread in new filter quality etc.

2.1.2.1. When granting such a derogation, the approval authority shall notify the manufacturer, the Commission, and all Members States of its decision.

2.2. Qualification process

2.2.1. For qualifying a deteriorated wall-flow DPF, the engine equipped with that wall-flow DPF shall be operated under stabilised steady-state conditions, set at the speed and load values specified for mode 9 in the WHSC test cycle specified in Annex 4B to UN/ECE Regulation No 49 (55 % normalised speed and 50 % normalised torque).

2.2.2. To qualify a deteriorated wall-flow DPF as a ‘Qualified Deteriorated Component’, the manufacturer shall demonstrate that the pressure drop across that deteriorated wall-flow DPF, measured when the engine system is operated under the conditions specified in Section 2.2.1, is no less than the percentage of the pressure drop across a clean and non-deteriorated DPF under the same conditions which is applicable in accordance with Sections 2.1.1 and 2.1.2 of this Appendix.

2.3. Demonstration of the OBD performance

2.3.1. The demonstration of the OBD performance shall be conducted in accordance with the requirements of Section 7.1.2 of Annex 9B to UN/ECE Regulation No 49 with the qualified deteriorated wall-flow DPF mounted on the parent engine system.

The replacement pollution control device to be evaluated shall be fitted to the exhaust after-treatment system tested according to the requirements of point 4.3.2.1, replacing the relevant original equipment exhaust after-treatment device.

The exhaust after-treatment system incorporating the replacement pollution control device shall then be preconditioned with 12 WHSC cycles. After this preconditioning, the engines shall be tested according to the WHDC procedures described in Annex 4B to UN/ECE Regulation No 49. Three exhaust gas tests of each appropriate type shall be performed.

4.3.2.3. Initial evaluation of the emission of pollutants of engines equipped with replacement pollution control devices

The requirements regarding emissions of the engines equipped with the replacement pollution control device shall be deemed to be fulfilled if the results for each regulated pollutant (CO, HC, NMHC, methane, NO

, NH

, particulate mass and particle number as appropriate for the type-approval of the engine) meet the following conditions:

(1) M ≤ 0,85S + 0,4G;

(2) M ≤ G

where:

mean value of the emissions of one pollutant obtained from the three tests with the replacement pollution control device.

mean value of the emissions of one pollutant obtained from the three tests with the original or original replacement pollution control device.

limit value of the emissions of one pollutant according to the type-approval of the vehicle.

4.3.2.4. Durability of emissions performance

The exhaust after-treatment system tested in point 4.3.2.2 and incorporating the replacement pollution control device shall be subjected to the durability procedures described in Appendix 4.

4.3.2.5. Exhaust gas test with aged replacement pollution control device

The aged exhaust after-treatment system incorporating the aged replacement control device shall then be fitted to the test engine used in points 4.3.2.1 and 4.3.2.2

The aged exhaust after-treatment systems shall be preconditioned with 12 WHSC cycles and subsequently tested using the WHDC procedures described in Annex 4B to UN/ECE Regulation No 49. Three exhaust gas tests of each appropriate type shall be performed.

4.3.2.6. Determination of ageing factor for the replacement pollution control device

The aging factor for each pollutant shall be the ratio of the applied emission values at the useful life end point and at the start of the service accumulation. (e.g. if the emissions of pollutant A at the useful life end point are 1,50 g/kWh and those at the start of the service accumulation are 1,82 g/kWh, the ageing factor is 1,82/1,50 = 1,21).

4.3.2.7. Evaluation of the emission of pollutants of engines equipped with replacement pollution control devices

The requirements regarding emissions of the engines equipped with the aged replacement pollution control device (as described in point 4.3.2.5) shall be deemed to be fulfilled if the results for each regulated pollutant (CO, HC, NMHC, methane, NO

, NH

, particulate mass and particle number as appropriate for the type-approval of the engine) meet the following condition:

M × AF ≤ G

where:

mean value of the emissions of one pollutant obtained from the three tests with the preconditioned replacement pollution control device before ageing (i.e. results from Section 4.3.2)

To belong to the same replacement pollution control device technology family the replacement pollution control devices shall have the following:

(a) the same emissions control mechanism (oxidation catalyst, three-way catalyst, particulate filter, selective catalytic reduction for NO

, etc.);

(b) the same substrate material (same type of ceramic, or same type of metal);

(d) the same catalytically active materials and, where more than one, the same ratio of catalytically active materials;

(e) the same total charge of catalytically active materials;

(f) the same type of washcoat applied by the same process.

4.3.4. Assessment of the durability of emissions performance of a replacement pollution control device by use of a technology family aging factor

Where the manufacturer has identified a replacement pollution control technology family, the procedures described in point 4.3.2 may be used to determine the Aging Factors (AFs) for each pollutant for the parent of that family. The engine on which these tests are conducted shall have a minimum engine displacement of [0,75 dm

] per cylinder.

4.3.4.1. Determination of durability performance of family members

A replacement pollution control device A within a family and intended to be mounted on an engine of displacement C

may be considered to have the same aging factors as the parent replacement pollution control device P, determined on an engine of displacement C

, if the following conditions are fulfilled:

≥ V

where:

Substrate volume (in dm

) of replacement pollution control device A

Substrate volume (in dm

) of the parent replacement pollution control device P of the same family; and

both engines use the same method for regeneration of any emissions control devices incorporated in the original exhaust after-treatment system. This requirement shall apply only where devices requiring regeneration are incorporated in the original exhaust after-treatment system.

If these conditions are fulfilled, the emissions durability performance of other members of the family may be determined from the emissions results (S) of that family member determined according to the requirements set out in points 4.3.2.1, 4.3.2.2 and 4.3.2.3 and using the Aging Factors determined for the parent of that family.

4.4. Requirements regarding exhaust back-pressure

4.5. Requirements regarding OBD compatibility (applicable only to replacement pollution control devices intended to be fitted to vehicles equipped with an OBD system)

4.5.1. OBD compatibility demonstration is required only when the original pollution control device was monitored in the original configuration.

4.5.2. The compatibility of the replacement pollution control device with the OBD system shall be demonstrated by using the procedures described in Annex X to this Regulation and Annex 9B to UN/ECE Regulation No 49 for replacement pollution control devices intended to be fitted to engines or vehicles type-approved in accordance with Regulation (EC) No 595/2009 and this Regulation.

4.5.3. The provisions in UN/ECE Regulation No 49 applicable to components other than pollution control devices shall not apply.

4.5.4. The replacement pollution control device manufacturer may use the same preconditioning and test procedure as used during the original type-approval. In this case, the approval authority which granted original type-approval of an engine of a vehicle shall provide, on request and on a non-discriminatory basis, Appendix on test conditions to Appendix 4 to Annex I which contains the number and type of preconditioning cycles and the type of test cycle used by the original equipment manufacturer for OBD testing of the pollution control device.

4.5.5. In order to verify the correct installation and functioning of all other components monitored by the OBD system, the OBD system shall indicate no malfunction and have no stored fault codes prior to the installation of any of the replacement pollution control device. An evaluation of the status of the OBD system at the end of the tests described in points 4.3.2 to 4.3.2.7 may be used for this purpose.

4.5.6. The malfunction indicator shall not activate during vehicle operation required by points 4.3.2 to 4.3.2.7.

5. CONFORMITY OF PRODUCTION

5.1. Measures to ensure the conformity of production shall be taken in accordance with Article 12 of Directive 2007/46/EC.

A ‘disable after fuelling’ system shall limit the vehicle speed to 20 km/h (creep mode) after the fuel tank level has risen a measurable amount, which shall not be more than 10 % of the fuel tank capacity and shall be approved by the approval authority based on the technical capabilities of the fuel level meter and a declaration by the manufacturer.

5.4.3. A ‘disable after parking’ system shall limit the vehicle speed to 20 km/h (creep mode) after the vehicle has been stationary for more than 1 hour.

5.4.4. A ‘disable on time limit’ system shall limit the vehicle speed to 20 km/h (creep mode) on the first occasion when the vehicle becomes stationary after 8 hours of engine operation if none of the systems described in Sections 5.4.1, 5.4.2 and 5.4.3 has previously been activated.

5.5. The driver inducement system shall be activated as specified in Sections 6.3, 7.3, 8.5, and 9.4.

5.5.1. When the driver inducement system has determined that the severe inducement system shall be activated, the low-level inducement system shall remain activated until the vehicle speed has been limited to 20 km/h (creep mode).

5.6. The driver inducement system shall be deactivated when the conditions for its activation have ceased to exist. The driver inducement system shall not be automatically deactivated without the reason for its activation having been remedied.

5.7. Details of the driver inducement system activation and deactivation procedures are described in Appendix 2.

5.8. As part of the application for type-approval under this Regulation, the manufacturer shall demonstrate the operation of the driver inducement system, as specified in Appendix 1.

6. REAGENT AVAILABILITY

6.1. Reagent indicator

The vehicle shall include a specific indicator on the dashboard that clearly informs the driver of the level of reagent in the reagent storage tank. The minimum acceptable performance level for the reagent indicator is that it shall continuously indicate the reagent level whilst the driver warning system referred to in Section 4 is activated to indicate problems with reagent availability. The reagent indicator may be in the form of an analogue or digital display, and may show the level as a proportion of the full tank capacity, the amount of remaining reagent, or the estimated driving distance remaining.

The reagent indicator shall be placed in close proximity to the fuel level indicator.

6.2. Activation of the driver warning system

6.2.1. The driver warning system specified in Section 4 shall be activated when the level of reagent is less than 10 % of the capacity of the reagent tank or a higher percentage at the choice of the manufacturer.

6.2.2. The warning provided shall be sufficiently clear for the driver to understand that the reagent level is low. When the warning system includes a message display system, the visual warning shall display a message indicating a low level of reagent. (for example, ‘urea level low’, ‘AdBlue level low’, or ‘reagent low’).

6.2.3. The driver warning system does not initially need to be continuously activated, however activation shall escalate in intensity so that it becomes continuous when the level of the reagent is approaching a very low proportion of the capacity of the reagent tank and the point where the driver inducement system will come into effect is approached. It shall culminate in a driver notification at a level that is at the choice of the manufacturer, but is sufficiently more noticeable than the point where the driver inducement system in Section 6.3 comes into effect.

6.2.4. The continuous warning shall not be easily disabled or ignored. When the warning system includes a message display system, an explicit message shall be displayed (for example. ‘fill up urea’, ‘fill up AdBlue’, or ‘fill up reagent’). The continuous warning may be temporarily interrupted by other warning signals providing important safety related messages.

6.2.5. It shall not be possible to turn off the driver warning system until the reagent has been replenished to a level not requiring its activation.

6.3. Activation of the driver inducement system

6.3.1. The low-level inducement system described in Section 5.3 shall be activated if the reagent tank level goes below 2,5 % of its nominally full capacity or a higher percentage at the choice of the manufacturer.

6.3.2. The severe inducement system described in Section 5.4 shall be activated if the reagent tank is empty (that is, the dosing system is unable to draw further reagent from the tank) or at any level below 2,5 % of its nominally full capacity at the discretion of the manufacturer.

6.3.3. It shall not be possible to turn off the low-level or severe driver inducement system until the reagent has been replenished to a level not requiring their respective activation.

7. REAGENT QUALITY MONITORING

min

shall be demonstrated during type-approval by the procedure defined in Appendix 6 and recorded in the extended documentation package as specified in Article 3 and Section 8 of Annex I.

7.1.2. Any reagent concentration lower than CD

min

shall be detected and be regarded, for the purpose of Section 7.1, as being incorrect reagent.

7.1.3. A specific counter (the reagent quality counter) shall be attributed to the reagent quality. The reagent quality counter shall count the number of engine operating hours with an incorrect reagent.

7.1.4. Details of the reagent quality counter activation and deactivation criteria and mechanisms are described in Appendix 2.

7.1.5. The reagent quality counter information shall be made available in a standardised manner in accordance with the provisions of Appendix 5.

7.2. Activation of the driver warning system

When the monitoring systems detects or, as appropriate, confirms that the reagent quality is incorrect, the driver warning system described in Section 4 shall be activated. When the warning system includes a message display system, it shall display a message indicating the reason for the warning (for example. ‘incorrect urea detected’, ‘incorrect AdBlue detected’, or ‘incorrect reagent detected’).

7.3. Activation of the driver inducement system

7.3.1. The low-level inducement system described in Section 5.3 shall be activated if the reagent quality is not rectified within 10 engine operating hours after the activation of the driver warning system described in Section 7.2.

7.3.3. The number of hours prior to activation of the inducement systems shall be reduced in case of a repetitive occurrence of the malfunction, in accordance with the mechanism described in Appendix 2.

8. REAGENT CONSUMPTION MONITORING

8.1. The vehicle shall include a means of determining reagent consumption and providing off-board access to consumption information.

8.2. Reagent consumption and dosing activity counters

8.2.1. A specific counter shall be attributed to the reagent consumption (the ‘reagent consumption counter’) and another to the dosing activity (the ‘dosing activity counter’). These counters shall count the number of engine operating hours which occur with an incorrect reagent consumption and, respectively, an interruption of the reagent dosing activity.

8.2.2. Details of the reagent consumption counter and dosing counter activation and deactivation criteria and mechanisms are described in Appendix 2 to this Annex.

(b) the flow of reagent or quantity of reagent injected at a position as close as technically possible to the point of injection into an exhaust after-treatment system.

8.4. Activation of the driver warning system

8.4.1. The driver warning system described in Section 4 shall be activated if a deviation of more than 20 % between the average reagent consumption and the average demanded reagent consumption by the engine system over a period to be defined by the manufacturer, which shall not be longer than the maximum period defined in Section 8.3.1, is detected. When the warning system includes a message display system, it shall display a message indicating the reason for the warning (for example, ‘urea dosing malfunction’, ‘AdBlue dosing malfunction’, or ‘reagent dosing malfunction’).

8.4.1.1. Until the end of the phase-in period specified in Article 4(7) the driver warning system described in Section 4 shall be activated if a deviation of more than 50 % between the average reagent consumption and the average demanded reagent consumption by the engine system over the period to be defined by the manufacturer, which shall not be longer than the maximum period defined in Section 8.3.1 is detected.

8.4.2. The driver warning system described in Section 4 shall be activated in the case of interruption in reagent dosing. When the warning system includes a message display system, it shall display a message indicating an appropriate warning. This activation shall not be required where the interruption is demanded by the engine ECU because the vehicle operating conditions are such that the vehicle’s emission performance does not require reagent dosing.

8.5. Activation of the driver inducement system

8.5.1. The low-level inducement system described in Section 5.3 shall be activated if an error in the reagent consumption or an interruption in reagent dosing is not rectified within 10 engine operating hours after the activation of the driver warning system specified in Sections 8.4.1 and 8.4.2.

(a) Impeding of the EGR valve operation;

(b) failures of the anti-tampering monitoring system, as described in Section 9.2.1.

9.2. Monitoring requirements

A non-exhaustive list of sensors that affect the diagnostic capability are those directly measuring NO

concentration, urea quality sensors, ambient sensors, and sensors used for monitoring reagent dosing activity, reagent level, or reagent consumption.

9.2.2. EGR valve counter

9.2.2.1. A specific counter shall be attributed to an impeded EGR valve. The EGR valve counter shall count the number of engine operating hours when the DTC associated with an impeded EGR valve is confirmed to be active.

9.2.2.2. Details of the EGR valve counter activation and deactivation criteria and mechanisms are described in Appendix 2 to this Annex.

9.4. Activation of the driver inducement system

9.4.1. The low-level inducement system described in Section 5.3 shall be activated if a failure specified in Section 9.1 is not rectified within 36 engine operating hours after the activation of the driver warning system in Section 9.3.

9.4.2. The severe inducement system described in Section 5.4 shall be activated if a failure specified in Section 9.1 is not rectified within 100 engine operating hours after the activation of the driver warning system in Section 9.3.

9.4.3. The number of hours prior to activation of the inducement systems shall be reduced in case of a repetitive occurrence of the malfunction in accordance with the mechanism described in Appendix 2.

If the manufacturer has opted for the ‘disable after restart’ approach referred to in Section 5.4.1, the vehicle shall be operated until the end of the current operating sequence, which must include a demonstration that the vehicle is capable of exceeding 20 km/h. After restart, the vehicle speed shall be limited to no more than 20 km/h.

5.4.6. If the manufacturer has opted for the ‘disable after fuelling’ approach referred to in Section 5.4.2, the vehicle shall be operated for a short distance, chosen by the manufacturer, after it has been brought to a state where there is sufficient spare capacity in the tank to permit it to be refuelled with the amount of fuel defined in Section 5.4.2. The vehicle operation before refuelling shall include a demonstration that the vehicle is capable of exceeding 20 km/h. After refuelling the vehicle with the amount of fuel defined in Section 5.4.2, the vehicle speed shall be limited to no more than 20 km/h.

Appendix 2

Description of the driver warning and inducement activation and deactivation mechanisms

1. To complement the requirements specified in this Annex concerning the driver warning and inducement activation and deactivation mechanisms, this Appendix specifies the technical requirements for an implementation of those activation and deactivation mechanisms consistent with the OBD provisions of Annex X.

All definitions used in Annex X are applicable to this Appendix.

2. ACTIVATION AND DEACTIVATION MECHANISMS OF THE DRIVER WARNING SYSTEM

2.1. The driver warning system shall be activated when the diagnostic trouble code (DTC) associated with a malfunction justifying its activation has the status defined in Table 1.

Table 1

Activation of the driver warning system

Failure type	DTC status for activation of the warning system
Poor reagent quality	confirmed and active
Low reagent consumption	potential (if detected after 10 hours), potential or confirmed and active otherwise
Absence of dosing	confirmed and active
Impeded EGR valve	confirmed and active
Malfunction of the monitoring system	confirmed and active

2.1.1. If the counter associated with the relevant failure is not at zero, and is consequently indicating that the monitor has detected a situation where the malfunction may have occurred for a second or subsequent time, the driver warning system shall be activated when the DTC has the status ‘potential’.

2.2. The driver warning system shall be deactivated when the diagnostic system concludes that the malfunction relevant to that warning is no longer present or when the information, including DTCs relative to the failures, justifying its activation is erased by a scan-tool.

2.2.1 Erasing of failure information by means of a scan-tool

2.2.1.1. Erasing of information, including DTCs relative to failures justifying the activation of a driver warning signal and of their associated data, by means of a scan-tool shall be performed in accordance with Annex 9B to UN/ECE Regulation No 49.

2.2.1.2. The erasing of failure information shall only be possible under ‘engine-off’ conditions.

2.2.1.3. When failure information, including DTCs, is erased, any counter associated with these failures and which is specified in this Annex as one that must not be erased shall not be erased.

3. ACTIVATION AND DEACTIVATION MECHANISM OF THE DRIVER INDUCEMENT SYSTEM

3.1. The driver inducement system shall be activated when the warning system is active and the counter relevant to the type of malfunction justifying its activation has reached the value specified in Table 2.

3.2. The driver inducement system shall be deactivated when the system no longer detects a malfunction justifying its activation, or if the information, including the DTCs, relative to the failures justifying its activation has been erased by a scan-tool or maintenance tool.

3.3. The driver warning and inducement systems shall be immediately activated or deactivated as appropriate in accordance with the provisions of Section 6 after assessment of the reagent quantity in the reagent tank. In that case, the activation or deactivation mechanisms shall not depend upon the status of any associated DTC.

4. COUNTER MECHANISM

4.1. General

4.1.1. To comply with the requirements of this Annex, the system shall contain at least four counters to record the number of hours during which the engine has been operated while the system has detected any of the following:

(a) an incorrect reagent quality;

(b) an incorrect reagent consumption;

(d) an impeded EGR valve;

(e) a failure of the monitoring system as defined in point (b) of Section 9.1.

4.1.2. Each of these counters shall count up to the maximum value provided in a 2 byte counter with 1 hour resolution, and shall hold that value unless the conditions allowing the counter to be reset to zero are met.

4.1.3. A manufacturer may use a single or multiple monitoring system counters.

A single counter may accumulate the number of hours of 2 or more different malfunctions relevant to that type of counter.

4.1.3.1. When the manufacturer decides to use multiple monitoring system counters, the system shall be capable of assigning a specific monitoring system counter to each malfunction that is relevant, in accordance with this Annex, to that type of counter.

4.2. Principle of counter mechanisms

4.2.1. Each of the counters shall operate as follows:

4.2.1.1.

If starting from zero, the counter shall begin counting as soon as a malfunction relevant to that counter is detected and the corresponding diagnostic trouble code (DTC) has the status described in Table 1.

4.2.1.2.

The counter shall halt and hold its current value if a single monitoring event occurs and the malfunction that originally activated the counter is no longer detected or if the failure has been erased by a scan-tool or a maintenance tool.

4.2.1.2.1.

If the counter stops counting when the severe inducement system is active, the counter shall be kept frozen at the value defined in Table 2.

4.2.1.2.2.

In the case of a single monitoring system counter, that counter shall continue counting if a malfunction relevant to that counter has been detected and its corresponding Diagnostic trouble code (DTC) has the status ‘confirmed and active’. It shall halt and hold the value specified in Section 4.2.1.2, or 4.2.1.2.1 as appropriate, if no malfunction that would justify the counter activation is detected or if all the failures relevant to that counter have been erased by a scan-tool or a maintenance tool.

Table 2

Counters and inducement

	DTC status for first activation of the counter	Counter value for low-level inducement	Counter value for severe inducement	Frozen value held by the counter during the period just after severe inducement
Reagent quality counter	confirmed and active	10 hours	20 hours	18 hours
Reagent consumption counter	potential or confirmed and active (see Table 1)	10 hours	20 hours	18 hours
Dosing counter	confirmed and active	10 hours	20 hours	18 hours
EGR valve counter	confirmed and active	36 hours	100 hours	95 hours
Monitoring system counter	confirmed and active	36 hours	100 hours	95 hours

4.2.1.3.

Once frozen, the counter shall be reset to zero when the monitors relevant to that counter have run at least once to completion of their monitoring cycle without having detected a malfunction and no malfunction relevant to that counter has been detected during 36 engine operating hours since the counter was last held (see Figure 1).

4.2.1.4.

The counter shall continue counting from the point at which it had been held if a malfunction relevant to that counter is detected during a period when the counter is frozen (see Figure 1).

5. ILLUSTRATION OF THE ACTIVATION AND DEACTIVATION AND COUNTER MECHANISMS

5.1. This Section illustrates the activation and deactivation and counter mechanisms for some typical cases. The figures and descriptions given in Sections 4.2, 4.3 and 4.4 are provided solely for the purposes of illustration in this Annex and should not be referenced as examples of either the requirements of this Regulation or as definitive statements of the processes involved. For simplification purposes, for example, the fact that the warning system will also be active when the inducement system is active has not been mentioned in the illustrations given.

5.2. Figure 2 illustrates the operation of the activation and deactivation mechanisms when monitoring the reagent availability for five cases:

(a) use case 1: the driver continues operating the vehicle in spite of the warning until vehicle operation is disabled;

(b) repair case 1 (‘adequate’ refilling): the driver refills the reagent tank so that a level above the 10 % threshold is reached. Warning and inducement are de-activated;

(c) repair cases 2 and 3 (‘inadequate’ refilling): The warning system is activated. The level of warning depends on the amount of available reagent;

(d) repair case 4 (‘very inadequate’ refilling): The low-level inducement is activated immediately.

5.3. Figure 3 illustrates three cases of wrong urea quality:

(a) use case 1: the driver continues operating the vehicle in spite of the warning until vehicle operation is disabled;

(b) repair case 1 (‘bad’ or ‘dishonest’ repair): after disablement of the vehicle, the driver changes the quality of the reagent, but, soon after, changes it again for a poor quality one. The inducement system is immediately reactivated and vehicle operation is disabled after 2 engine operating hours;

(c) repair case 2 (‘good’ repair): after disablement of the vehicle, the driver rectifies the quality of the reagent. However, some time afterwards, he refills again with a poor quality reagent. The warning, inducement, and counting processes restart from zero.

5.4. Figure 4 illustrates three cases of failure of the urea dosing system. This figure also illustrates the process that applies in the case of the monitoring failures described in Section 9.

(a) Use case 1: the driver continues operating the vehicle in spite of the warning until vehicle operation is disabled.

(b) Repair case 1 (‘good’ repair): after disablement of the vehicle, the driver repairs the dosing system. However, some time afterwards, the dosing system fails again. The warning, inducement, and counting processes restart from zero.

(c) Repair case 2 (‘bad’ repair): during the low-level inducement time (torque reduction), the driver repairs the dosing system. Soon after, however, the dosing system fails again. The low-level inducement system is immediately reactivated and the counter restarts from the value it had at the time of repair.

Appendix 4

Demonstration of correct installation on a vehicle in the case of engines EC type-approved as a separate technical unit

This Appendix applies when the vehicle manufacturer requests EC type-approval of a vehicle with an approved engine with regard to emissions and access to vehicle repair and maintenance information in accordance with this Regulation and Regulation (EC) No 595/2009.

In this case, and in addition to the installation requirements of Annex I, a demonstration of the correct installation is required. This demonstration shall be performed by the presentation to the approval authority of a technical case using evidence such as engineering drawings, functional analyses, and the results of previous tests.

Where appropriate, and if the manufacturer chooses, the evidence presented may include installations of systems or components on real or simulated vehicles, provided that the manufacturer can present evidence that the presented installation properly represents the standard that will be achieved in production.

The demonstration shall address the conformity of the following elements to the requirements of this Annex:

(a) the installation on board the vehicle as regards its compatibility with the engine system (hardware, software and communication);

(b) the warning and inducement systems (for example, pictograms, activation schemes, etc.);

(c) the reagent tank and the elements (for example, sensors) mounted on the vehicle for the purpose of complying with this Annex.

Correct activation of the warning and inducement systems, and of the information storage and on-board and off-board communication systems, may be checked. No check of these systems shall require the dismounting of the engine system or components, nor shall it generate unnecessary testing burden by requiring processes such as changing of the urea quality or running of the vehicle or engine for long periods of time. In order to minimise the burden upon the vehicle manufacturer, electric disconnections and simulation of counters with high operating hours shall be selected as checks on these systems if possible.

Appendix 5
