Commission Directive 2003/27/EC

of 3 April 2003

on adapting to technical progress Council Directive 96/96/EC as regards the testing of exhaust emissions from motor vehicles

(Text with EEA relevance)

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community,

Having regard to Council Directive 96/96/EC of 20 December 1996 on the approximation of the laws of the Member States relating to roadworthiness tests for motor vehicles and their trailers(1), as last amended by Commission Directive 2001/11/EC(2), and in particular Article 7(2) thereof,

Whereas:

(1) The Auto-Oil programmes, which were initiated in 1992 to provide the analytical foundation for the setting of vehicle emission and fuel quality standards for the year 2000 and beyond, in order to achieve air quality objectives with a particular focus on reducing road transport emissions, identified the standard of motor vehicle maintenance as a key factor in the effect of traffic on air quality.

(2) Directive 96/96/EC specifies the tests to be carried out at periodic inspections to check that emissions from both petrol and diesel driven vehicles are still within acceptable limits.

(3) A working group of experts from the International Motor Vehicle Inspection Committee (CITA), and from other relevant organisations was established by the Commission and met during year 2000. The group examined the options for amending the limits for the emission tests prescribed in Directive 96/96/EC and in Directive 2000/30/EC of the European Parliament and of the Council of 6 June 2000 on the technical roadside inspection of the roadworthiness of commercial vehicles circulating in the Community(3) to determine whether improved environmental benefits could be realised. The Group concluded that the currently prescribed limits are invariably well above what the vehicle is capable of achieving in practice, provided that it is properly maintained: the current limits are therefore not as effective as they could be in facilitating the detection of gross emitters, i.e. vehicles whose exhaust emissions are at least 50 % more than would be expected from a properly maintained vehicle.

(4) The measures provided for in this Directive are in accordance with the opinion of the committee for the adaptation to technical progress of the Directive on roadworthiness tests for motor vehicles and their trailers instituted by Article 8 of Directive 96/96/EC,

HAS ADOPTED THIS DIRECTIVE:

ANNEX

The fourth indent to point 7.10 of Annex II to Directive 96/96/EC is replaced by the following:

"- check wherever practical that the speed limitation device prevents vehicles mentioned in Article 2 and Article 3 of Directive 92/6/EEC from exceeding the prescribed values."

Point 8.2 of Annex II to Directive 96/96/EC is replaced by the following:

"8.2. Exhaust emissions

8.2.1. Motor vehicles equipped with positive-ignition engines and fuelled by petrol

(a) Where the exhaust emissions are not controlled by an advanced emission control system such as a three-way catalytic converter that is lambda-probe controlled:

1. Visual inspection of the exhaust system in order to check that it is complete and in a satisfactory condition and that there are no leaks.

2. Visual inspection of any emission control equipment fitted by the manufacturer in order to check that it is complete and in a satisfactory condition and that there are no leaks.

After a reasonable period of engine conditioning (taking account of manufacturer's recommendations) the carbon monoxide (CO) content of the exhaust gases is measured when the engine is idling (no load).

The maximum permissible CO content in the exhaust gases is that stated by the vehicle manufacturer. Where this information is not available or where the Member States' competent authorities decide not to use it as a reference value, the CO content must not exceed the following:

(i) for vehicles registered or put into service for the first time between the date from which Member States required the vehicles to comply with Directive 70/220/EEC(1) and 1 October 1986: CO - 4,5 % vol.

(ii) For vehicles registered or put into service for the first time after 1 October 1986 - 3,5 % vol.

(b) Where the exhaust emissions are controlled by an advanced emission control system such as a three-way catalytic converter that is lambda-probe controlled:

1. Visual inspection of the exhaust system in order to check that it is complete and in a satisfactory condition and that there are no leaks.

2. Visual inspection of any emission control equipment fitted by the manufacturer in order to check that it is complete and in a satisfactory condition and that there are no leaks.

3. Determination of the efficiency of the vehicle's emission control system by measuring the lambda value and the CO content of the exhaust gases in accordance with section 4 or with the procedures proposed by the manufacturers and approved at the time of type-approval. For each of the tests the engine is conditioned in accordance with the vehicle manufacturer's recommendations.

4. Exhaust pipe emissions - limit values

The maximum permissible CO content in the exhaust gases is that stated by the vehicle manufacturer. Where this information is not available the CO content must not exceed the following:

(i) Measurement at engine idling speed:

The maximum permissible CO content in the exhaust gases must not exceed 0,5 % vol. and for vehicles that have been type-approved according to the limit values shown in row A or row B of the table in section 5.3.1.4. of Annex I to Directive 70/220/EEC, as amended by Directive 98/69/EC(2) or later amendments the maximum CO content must not exceed 0,3 % vol. Where identification to Directive 70/220/EEC, as amended by Directive 98/69/EC is not possible then the above shall apply to vehicles registered or first put into service after 1 July 2002.

(ii) Measurement at high idle speed (no load), engine speed to be at least 2000 min-1:

CO content: maximum 0,3 % vol. and for vehicles that have been type-approved according to the limit values shown in row A or row B of the table in section 5.3.1.4. of Annex I to Directive 70/220/EEC, as amended by Directive 98/69/EC or later amendments the maximum CO content must not exceed 0,2 % vol. Where identification to Directive 70/220/EEC, as amended by Directive 98/69/EC is not possible then the above shall apply to vehicles registered or first put into service after 1 July 2002.

Lambda: 1± 0,03 or in accordance with the manufacturer's specifications.

(iii) For motor vehicles equipped with on-board diagnostic systems (OBD) in accordance with Directive 70/220/EEC (as amended by Directive 98/69/EC and subsequent amendments) Member States may as an alternative to the test specified in item (i) establish the correct functioning of the emission system through the appropriate reading of the OBD device and the simultaneous checking of the proper functioning of the OBD system.

8.2.2. Motor vehicles equipped with compression-ignition (diesel) engines

(a) Exhaust gas opacity to be measured during free acceleration (no load from idle up to cut-off speed) with gear lever in neutral and clutch engaged.

(b) Vehicle preconditioning:

1. Vehicles may be tested without preconditioning although for safety reasons checks should be made that the engine is warm and in a satisfactory mechanical condition.

2. Except as specified in subparagraph (d)(5), no vehicle will be failed unless it has been preconditioned according to the following requirements:

(i) Engine shall be fully warm, for instance the engine oil temperature measured by a probe in the oil level dipstick tube to be at least 80 °C, or normal operating temperature if lower, or the engine block temperature measured by the level of infrared radiation to be at least an equivalent temperature. If, owing to vehicle configuration, this measurement is impractical, the establishment of the engine's normal operating temperature may be made by other means, for example by the operation of the engine cooling fan.

(ii) Exhaust system shall be purged by at least three free acceleration cycles or by an equivalent method.

(c) Test procedure:

1. Visual inspection of any emission control equipment fitted by the manufacturer in order to check that it is complete and in a satisfactory condition and that there are no leaks.

2. Engine and any turbocharger fitted, to be at idle before the start of each free acceleration cycle. For heavy-duty diesels, this means waiting for at least 10 seconds after the release of the throttle.

3. To initiate each free acceleration cycle, the throttle pedal must be fully depressed quickly and continuously (in less than one second) but not violently, so as to obtain maximum delivery from the injection pump.

4. During each free acceleration cycle, the engine shall reach cut-off speed or, for vehicles with automatic transmissions, the speed specified by the manufacturer or if this data is not available then two thirds of the cut-off speed, before the throttle is released. This could be checked, for instance, by monitoring engine speed or by allowing a sufficient time to elapse between initial throttle depression and release, which in the case of vehicles of category 1 and 2 of Annex 1, should be at least two seconds.

(d) Limit values:

1. The level of concentration must not exceed the level recorded on the plate pursuant to Directive 72/306/EEC(3).

2. Where this information is not available or where Member States' competent authorities decide not to use it as a reference, the level of concentration must not exceed the level stated by the manufacturer or the limit values of the coefficient of absorption that are as follows:

Maximum coefficient of absorption for:

- naturally aspirated diesel engines = 2,5 m-1

- turbo-charged diesel engines = 3,0 m-1

- a limit of 1,5 m-1 shall apply to the following vehicles that have been type-approved according to the limit values shown in:

(a) row B of the table in section 5.3.1.4 of Annex I to Directive 70/220/EEC, as amended by Directive 98/69/EC - (Light Duty Vehicle Diesel - Euro4);

(b) row B1 of the tables in section 6.2.1 of Annex I to Directive 88/77/EEC, as amended by Directive 1999/96/EC(4) - (Heavy Duty Vehicle Diesel - Euro4);

(c) row B2 of the tables in section 6.2.1 of Annex I to Directive 88/77/EEC, as amended by Directive 1999/96/EC - (Heavy Duty Vehicle Diesel - Euro5);

(d) row C of the tables in section 6.2.1 of Annex I to Directive 88/77/EEC, as amended by Directive 1999/96/EC - (Heavy Duty Vehicle - EEV)

or limit values in later amendments of Directive 70/220/EEC as amended by Directive 98/69/EC, or limit values in later amendments of Directive 88/77/EEC as amended by Directive 1999/96/EC, or equivalent values where use is made of equipment of a type different from that used for EC type-approval.

Where identification to section 5.3.1.4 of Annex I to Directive 70/220/EEC, as amended by Directive 98/69/EC or to section 6.2.1 of Annex I to Directive 88/77/EEC, as amended by Directive 1999/96/EC is not possible then the above shall apply to vehicles registered or first put into service after 1 July 2008.

3. Vehicles registered or put into service for the first time before 1 January 1980 are exempted from these requirements.

4. Vehicles shall only be failed if the arithmetic means of at least the last three free acceleration cycles are in excess of the limit value. This may be calculated by ignoring any measurement that departs significantly from the measured mean, or the result of any other statistical calculation that takes account of the scattering of the measurements. Member States may limit the number of test cycles.

5. To avoid unnecessary testing, Member States may, by way of exception from the provisions of paragraph 8.2.2(d)(4), fail vehicles which have measured values significantly in excess of the limit values after less than three free acceleration cycles or after the purging cycles (or equivalent) specified in subparagraph 8.2.2(b)2(ii). Equally to avoid unnecessary testing, Member States may, by way of exception from the provisions of 8.2.2(d)(4) pass vehicles which have measured values significantly below the limits after less than three free acceleration cycles or after the purging cycles (or equivalent) specified in subparagraph 8.2.2(b)2(ii).

8.2.3. Test equipment

Vehicle emissions are tested using equipment designed to establish accurately whether the limit values prescribed or indicated by the manufacturer have been complied with.

8.2.4. Where, during EC type-approval, a type of vehicle is found not to have satisfied the limit values laid down by this directive, the Member States may lay down higher limit values for that type of vehicle on the basis of proof supplied by the manufacturer. They must forthwith inform the Commission thereof and it in turn must inform the other Member States."
