Commission Regulation (EU) No 582/2011Show full title

2. GENERAL REQUIREMENTS

2.1. The general requirements, including the specific requirements for electronic system security, shall be those set out in Section 4 of Annex 9B to UN/ECE Regulation No 49 and those described in Section 2 of this Annex.

2.2. The reference to Driving cycle in Annex 9C to UN/ECE Regulation No 49 shall be read as reference to Driving cycle as defined in Article 2(36) of this Regulation.

2.3. Additional provisions concerning monitoring requirements

2.3.1. In addition to the monitoring requirements set out in Appendix 3 to Annex 9B to UN/ECE Regulation No 49 the monitoring requirements set out in Appendix 1 to this Annex shall apply.

2.3.1.1. The failure classification rules shall be the ones set out in Annex 9B to UN/ECE Regulation No 49. Failures detected by the additional monitors required by Appendix 1 shall not be classified as class C failures(1).

2.3.2. In the case where the control of reagent injection is performed by means of a closed-loop system, the monitoring requirements set out in Item 1 of Appendix 3 to Annex 9B to UN/ECE Regulation No 49 shall apply.

2.3.2.1. Failures detected according to the provisions of 2.3.2 shall not be classified as class C failures.

2.3.3. The monitoring requirements concerning particulate aftertreatment devices set out in Item 2(c) of Appendix 3 to Annex 9B to UN/ECE Regulation No 49 shall be understood and complemented as set out in points 2.3.3.1, 2.3.3.2 and 2.3.3.3.

2.3.3.1 The performance of the particulate aftertreatment device including the filtration and continuous regeneration processes shall be monitored against the OBD threshold limit specified in Table 1.

2.3.3.2. The periodic regeneration shall be monitored against the ability of the device to perform as designed (for example to perform regeneration within a manufacturer-specified time interval, to perform regeneration upon demand, etc.). This shall constitute one element of the component monitoring associated with the device.

2.3.3.3. Before the dates specified in Article 4(8) and in the case of a wall-flow diesel particulate filter (DPF), the manufacturer may choose to apply the performance monitoring requirements set out in Appendix 3 to this Annex instead of the requirements of Section 2.3.3.1, if he can demonstrate with technical documentation that in case of deterioration there is a positive correlation between the loss of filtration efficiency and the loss of pressure drop (delta pressure) across the DPF under the operating conditions of the engine specified in the test described in Appendix 3 to this Annex.

2.3.3.4. The Commission shall conduct a review of the monitoring requirements set out in point 2.3.3.1 by 31 December 2012. In case the technical non-feasibility of the respective requirements by the dates indicated in point 2.3.3.3 is demonstrated, the Commission shall make a proposal for amending these dates accordingly.

2.4. Alternative approval

2.4.1. If requested by the manufacturer, for vehicles of category M₁, M₂, N₁ and N₂ with a maximum permissible mass not exceeding 7,5 tonnes and M₃ Class I, Class II and Class A and Class B as defined in Annex I to Directive 2001/85/EC with a permissible mass not exceeding 7,5 tonnes, compliance with the requirements of Annex XI to Regulation (EC) No 692/2008 according to OBD standard Euro 6 as defined in Appendix 6 to Annex I to Regulation (EC) No 692/2008 shall be considered equivalent to the compliance with this Annex.

If such alternative approval is used, the information related to OBD systems in Sections 3.2.12.2.7.1 to 3.2.12.2.7.4 of Part 2 of Appendix 4 to Annex I is replaced by the information of Section 3.2.12.2.7 of Appendix 3 to Annex I to Regulation (EC) No 692/2008.

Selective application of the provisions of this Annex and of the provisions of Annex XVI to Regulation (EC) No 692/2008 shall not be permitted except to the extent explicitly set out in Section 2.4.1.

2.4.2. Small series production

As an alternative to the requirements set out in Section 4 of Annex 9B to UN/ECE Regulation No 49 and those described in this Annex, engine manufacturers whose world-wide annual production of engines within an engine type subject to this Regulation is less than 500 engines per year, may obtain EC type-approval on the basis of the other requirements of this Regulation when the emission control components of the engine system are at least monitored for circuit continuity, and for rationality and plausibility of sensor outputs, and when the aftertreatment system is at least monitored for total functional failure. Engine manufacturers whose world-wide annual production of engines within an engine type subject to this Regulation is less than 50 engines per year, may obtain EC type-approval on the basis of the requirements of this Regulation when the emission control components of the engine system are at least monitored for circuit continuity, and for rationality and plausibility of sensor outputs (component monitoring).

2.4.3. A manufacturer shall not be permitted to use the alternative provisions specified in Section 2.4.1 for more than 500 engines per year.

2.4.4. The approval authority shall inform the Commission of the circumstances of each type-approval granted under Sections 2.4.1 and 2.4.2.

2.5. Conformity of production

The OBD system is subject to the requirements for conformity of production specified in Directive 2007/46/EC.

If the approval authority decides that verification of the conformity of production of the OBD system is required, the verification shall be conducted in accordance with the requirements specified in Annex I to this Regulation.
