Combustion and engine technologies

Vehicle approval certifies that the emissions of said vehicle meet the specifications imposed by existing standards. Although current regulations only concern a limited number of chemical species ,

Gasoline direct injection engines emit soot particles during rapid transients . This still poorly understood phenomenon is taken into account during new WLTCs a , aimed at more accurately reproducing

The reduction in IC engine particle emissions requires a detailed knowledge of the physicochemical processes at work during combustion . While fuels have long since been considered as a constant for
