Sustainable mobility

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 ,

In order to reduce fuel consumption in gasoline engines , manufacturers are focusing their efforts on turbocharging and downsizing . However, this option leads to an increase in the knock phenomenon

In the aviation sector, fuels derived from hydrotreated vegetable oils (HEFA a ) are seen as an alternative to petroleum based Jet A-1 b to reduce the environmental footprint of air transport .

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
