Les véhicules diesel ont un rendement énergétique plus élevé, mais ils produisent davantage de particules que les moteurs à essence ordinaires. Il existe deux moyens efficaces de réduire considérablement les émissions de particules du moteur diesel : le filtre à particules, et l’utilisation de biodiesel. En effet, la composition du carburant a un impact direct sur la combustion, et donc sur les émissions de polluants. Une teneur élevée en biodiesel permet de réduire le nombre de particules produites. Plus la quantité de biodiesel dans le carburant mélangé est importante, moins des particules sont émises. Lorsque les technologies de filtre et de biodiesel sont combinées, les émissions de particules sont quasi-inexistantes.
Abstract
Diesel vehicles have higher fuel efficiency however they produce more particles than common gasoline motors. There are two efficient ways to drastically reduce those particulates emission from diesel motor. First particles filter, second biodiesel uses. Indeed the fuel composition has a direct impact on combustion, and therefore on pollutant emissions. A high content of biodiesel makes it possible to reduce the number of particles produced. The more the content of biodiesel in the fuel mixed, the less particles are emitted. When both filter and biodiesel technologies are used together the particles emission are almost inexistent.
