Subject: for Euro 6 OBD and Euro 6 PN limit for gasoline direct injection engines. Amendments to Regulations 715/007 (1) Regulation 566/011 (3) and 69/008 (), as amended by Note: ACEA s initial comments on OBD are available on the website of the TCMV held on 17 th June 011 (4). This new document deals with both Euro 6 OBD threshold limits and the PN limit for gasoline direct injection engines, two remaining and important issues which must be discussed, agreed and adopted as a package before the end of this year. It is based on document (5) which was discussed at TCMV on 17 th June 011 under agenda item 9. General summary: ACEA urges the legislators to quickly complete both the OBD threshold limits and the PN limit for gasoline direct injection engines, both of which are needed for Euro 6 approvals that are mandatory from the dates given in Article 10(4) and 10(5) of Regulation 715/007. The Commission should make a proposal covering both of these issues as soon as possible and the TCMV should vote on the proposal by the end of this year, at the latest. In making such a proposal, it is recognised that the proposal for the gasoline engine PN limit and the OBD threshold limits may be made in two parts an initial set of limits to apply immediately for Euro 6 approvals and a further reflection on those limits via a full and proper impact assessment conducted in a timely manner to determine if a further reductions are technically feasible and necessary. Such an assessment and adoption and entry into force of any necessary legislation should result in industry having at least 4 years lead-time before any new measures were to apply. In addition, ACEA urges the member states and the Commission to decide that all of the open issues regarding future environmental requirements in Euro 6 (and other Regulations) which still remain to be discussed and agreed, either through co-decision or comitology must, as far as possible, be applied from a common date framework in the future and with sufficient industry leadtime. In this respect the current practice of granting vehicles of category N1 classes II and III and category N an extra one year for meeting future emission requirements should be maintained. Moreover, the Commission as a major stakeholder in the UN-ECE WLTP program must, by all means, ensure the consistency between the application dates of the new WLTP and of future new EU Regulations. Industry cannot again face the complicated situation of Euro 5. It is against the principles of better regulation established and supported through CARS1.

Amendments to Regulation 715/007 and 69/008 for introducing the Euro 6 OBD threshold limits and the Euro 6 gasoline PN limit A. Amendments to Regulation 715/007: 1. The following paragraph 7 shall be added to Article 10: 7. The PI emission limit for number of particles referred to in Table of Annex I and the OBD limits shown in the Table in paragraph.3.4 of Annex XI shall be effective from the applicable dates set out in paragraphs 4 and 5.. Table of Annex I is replaced by the following table:

() Any further reduction of the values in this column is pending the review outlined in Article 14(7).
3. The following paragraphs 9 and 10 shall be added to Article 10: 9. Subject to Article 14(7), with effect from 1 September 017, and from 1 September 018 in the case of category N1 class II and III and category N vehicles, the national authorities shall refuse, on grounds relating to emissions or fuel consumption, to grant EC type approval or national type approval for new types of vehicle which do not comply with this Regulation and its implementing measures, and in particular with the particle number limit for positive ignition direct injection engines set out in Table of Annex I and the OBD threshold limit values set out in the table in paragraph.3.3 of Annex XI. 10. Subject to Article 14(7), with effect from 1 September 018, and from 1 September 019 in the case of category N1 class II and III and category N vehicles, national authorities shall, in the case of new vehicles which do not comply with this Regulation and its implementing measures, and in particular with the particle number limit for positive ignition direct injection engines set out in Table of Annex I and the OBD threshold limit values set out in the table in paragraph.3.3 of Annex XI, consider certificates of conformity to be no longer valid for the purposes of Article 7(1) of Directive 70/156/EEC and shall, on grounds relating to emissions or fuel consumption, prohibit the registration, sale or entry into service of such vehicles. 4. The following paragraphs 7 and 8 shall be added to Article 14: 7. Understanding that exhaust aftertreatment technology to control the emission of particles from direct injection positive-ignition engines is still relatively new and unproven at a wide industrial level, especially in relation to the stability and mode of regeneration, durability, capability for OBD monitoring and effects on fuel consumption and CO, the Commission shall conduct a review of the technical feasibility, environment and health benefit and cost effectiveness of reducing the emission limit for number of particles from direct injection positive-ignition engines shown in the respective column of Table. According to the results of this review, the Commission should either confirm or make an appropriate regulatory proposal to lower the limit for number of particles from direct injection positive-ignition engines shown in the respective column of Table and/or the mandatory date of application, at least 4 years before the earlier date in Article 10(9). 8. The Commission shall conduct a review of the indicative final OBD threshold limits shown in the table in paragraph.3.3 of Annex XI. If the cost effectiveness and technical feasibility for the prescribed introduction timing is demonstrated, the Commission shall confirm their values at least 4 years before the earlier date in Article 10(9). If the cost-effectiveness or the technical feasibility for the prescribed introduction timing is not demonstrated, or the review is not completed, the Commission shall make a proposal to amend their values and/or the mandatory dates of application shown in Article 10(9) and 10(10) and adopt such a proposal at least 4 years before the earlier date in Article 10(9). In respect of presently non-quantified partial failures of a diesel particle filter and to consider any further reduction in the diesel NOx OBD threshold limit, the Commission shall, in particular, review of the technical feasibility and cost effectiveness of the diesel NOx and PM OBD threshold limits specified in the respective columns of the table in section.3.3. The review shall also assess the environmental and human health benefit and the technical feasibility of an OBD threshold limits for the number of emitted particles (PN) and of the technical feasibility of CO and NMHC OBD threshold limits ensuring a robust monitoring of the diesel oxidation catalyst (DOC) for partial failures. Depending on the results of this review the Commission should make an appropriate regulatory proposal.

Section.14 in Annex XI (introduced in Regulation 566/011) is replaced by the following:.14. In deviation from point 3.3.5 of Annex 11 to UN/ECE Regulation No 83, As from 1 September 011 in the case of a particulate trap fitted to diesel engines as a separate unit or integrated into a combined emission control device and, for vehicles certified against either the OBD threshold limits shown in the table in section.3.3 or.3.4 in the case of DOC and NOx aftertreatment devices fitted to diesel engines as a separate unit or integrated into a combined emission control device, such devices shall always be monitored at least for total failure or removal if the latter resulted in exceeding the applicable emission limits. Such devices shall also be monitored for any failure that would result in exceeding the applicable OBD threshold limits. 5. Point 6. (a) of Annex XVI (introduced in Regulation 566/011) is replaced by the following: a. For the purposes of this point these situations are presumed to occur, if the applicable NOx emission limit of Table 1 of Annex I to Regulation (EC) No 715/007, multiplied by a factor of 1,5, is exceeded. For a vehicle approved to the interim Euro 6 OBD threshold limits of point.3. of Annex XI to this Regulation or the preliminary Euro 6 OBD threshold limits of point.3.4 of Annex XI to this Regulation, those situations are presumed to occur if the applicable NOx emission limit of Table of Annex I to Regulation (EC) No 715/007 is exceeded by 100 mg or more. NOx emissions during the test to demonstrate compliance with these requirements shall be not more than 0% higher than the values referred to in the first and second sentence. 8
