Assessment of particle number limits for petrol vehicles
The European Commission Regulations No 692/2008 and No 715/2007 set the regulatory framework for type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5/6). However, these regulations leave open some issues regarding the Euro 6 emission standards to be addressed and defined before the entry into force of these pieces of legislation. Among them, the Type I test particle number limit for vehicles equipped with Positive Ignition Direct Injection engines should be defined.
The Joint Research Centre has carried out a study to support a possible implementation of such a limit for Euro 6 petrol vehicles. The first part of this report provides a review of the particle mass and number emissions of gasoline Port Fuel Injection (PFI) and Gasoline Direct Injection (G-DI) vehicles available in the literature. Over the second part, the particle mass and number emissions from a range of Euro 4 and Euro 5 gasoline vehicle/engine technology measured at JRC are synopsized. The vehicles have been tested over various driving cycles and ambient temperature conditions according to the Particle Measurement Programme (PMP) methodology.
