摘要
Abstract
Particulate matter(PM)emissions and soot nanostructure were studied on a gasoline direct inj ection engine withmesitylene blended fuels based on China Ⅴ standard gasoline.The results indicate that PM emissions increase with load and decrease with the increase of speed over low and medium speeds.A higher proportion of aromatics will lead to higher PM emissions and lower oxidation of soot at high load.A higher proportion of aromatics will lead to more precursor and higher graphitic lamellae of soot,preventing PM from secondary oxidation,thus reducing PM emissions.关键词
