Regulation (EC) No 715/2007 and Commission Regulation (EC) No 692/2008 of 18 July 2008 implementing and amending Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information (3) establish common technical requirements for the type approval of motor vehicles and replacement parts with regard to their emissions and lay down rules for in-service conformity, durability of pollution control devices, on-board diagnostic (OBD) systems, measurement of fuel consumption and accessibility of vehicle repair and maintenance information.

(2)

Pursuant to Regulation (EC) No 715/2007, a particle number (PN) standard is to be defined for vehicles equipped with a positive ignition engine to be approved according to Euro 6 standards.

(3)

Particles emitted by vehicles may be deposited in the alveoli of human lungs, potentially leading to respiratory and cardiovascular illness and increased mortality. Therefore it is in the public interest to have a high level of protection from those particles.

(4)

For measuring the particle emissions of positive ignition vehicles, the Particulate Measurement Programme (PMP) measurement protocol developed for diesel vehicles is currently used. However, evidence exists that the size spectra and chemical compositions of particle emissions of positive ignition can differ from those of diesel vehicles. Particle size spectra and chemical composition, and the effectiveness of the current measurement technique in controlling harmful particle emissions, should be kept under review. A revision of that measurement protocol for positive ignition vehicles may be required in the future.

(5)

Based on today’s knowledge, the level of particle emissions from conventional, port fuel injection (PFI) engines that inject the fuel into the intake manifolds or inlet ports rather than directly into the combustion chamber is low. Therefore, it appears to be justified to limit regulatory action for the moment to vehicles equipped with direct injection engines, without excluding further research and monitoring of the particle emission performance of all positive ignition engines, in particular with respect to the size spectrum and chemical composition of emitted particles as well as to the real driving emissions, and the Commission should propose further regulatory measures if necessary, also taking into account the future market share of PFI engines.

(6)

Regulation (EC) No 692/2008 has set a particle number emission limit of 6 × 1011 #/km for Euro 6 diesel vehicles. In accordance with the principle of technology neutral legislation, a respective emission limit for Euro 6 positive ignition vehicles should be the same since there is no evidence suggesting that particles emitted by PI engines have a lower specific toxicity than particles emitted by diesel engines.

(7)

Gasoline particle filters (GPF), an effective after-treatment technology for abating particles emitted by positive ignition vehicles, are expected to become available for integration into some Euro 6 vehicles at a reasonable cost. In addition, it appears likely that within a time frame of three years after the mandatory Euro 6 dates set out in Article 10 of Regulation (EC) No 715/2007, a similar reduction of PN emissions can be achieved with internal engine measures at substantially lower costs for many applications. Any engine measure must be applicable to all engine working conditions to ensure that, in the absence of aftertreatment devices, emission levels in real life driving conditions are not worsened.

(8)

In order to allow for all necessary technologies to be developed and to allow adequate lead time, a two step approach should be adopted, which would apply the Euro 6 diesel particle number limits also to direct injection positive ignition vehicles in its second phase.

(9)

Attention shall be given to the particle emissions of positive ignition vehicles under real driving conditions and the development of respective test procedures. The Commission should develop and introduce corresponding measurement procedures at the latest three years after the entry into force of Euro 6.

(10)

The Commission should keep under review the impact of PN abatement measures on CO2 emissions of positive ignition vehicles.

(11)

Pursuant to Article 4(7) of Regulation (EC) No 692/2008, vehicles falling under the scope of that Regulation may only be type-approved to Euro 6 emission standards once on-board-diagnostic (OBD) thresholds limits have been introduced. OBD is an important tool for identifying malfunctions of pollution control devices.

(12)

In its Communication 2008/C 182/08 on the application and future development of Community legislation concerning vehicle emissions from light-duty vehicles and access to repair and maintenance information (Euro 5 and 6) (4) the Commission has suggested a series of OBD threshold limits, which broadly reflect the thresholds applied to most light duty vehicles in the United States and Canada from the year 2013 onwards, where the majority of vehicles’ OBD systems are compliant with the legislation set by the Californian Air Resources Board (CARB). An alignment of the Union’s requirements with those of the United States would be in accordance with the objectives of international harmonisation and would provide a high level of environmental protection.

(13)

However, the OBD requirements in the United States are technologically challenging for vehicle manufacturers not exporting into the United States. Therefore, an initial period of three years of more lenient OBD requirements should be adopted, providing more lead time to the industry.

(14)

The final Euro 6 OBD threshold limits for CO, NMHC and PM provided by Regulation (EC) No 692/2008 should be more lenient than the values suggested in Communication 2008/C 182/08, reflecting particular technical difficulties in those areas. In addition, no Euro 6 OBD threshold limit for particle numbers should be adopted by this Regulation.

(15)

The environmental need, technical feasibility and cost/benefit ratios of more stringent Euro 6 OBD threshold limits applicable to CO and NMHC and of setting a particle number Euro 6 OBD threshold limit should be evaluated at a later stage. Any resulting amendment of the regulatory requirements in that respect should only be introduced with appropriate lead time for industry. Given the complexity of OBD systems, such lead time is typically three to four years.

(16)

Regulations (EC) No 715/2007 and (EC) No 692/2008 should therefore be amended accordingly.
