Motor vehicles, especially diesel vehicles, contribute to a large part of atmospheric PM2.5. Therefore, it is important to control the emissions of diesel engines by understanding the inherent relationship between fuel properties and exhaust particle. In this paper, several fuels with different physicochemical characteristics available for the compression ignition engine, were studied by using the SMPS, HRTEM, TGA, thermal optical carbon analyzer and GC-MS. The effect of fuel properties, such as contents of sulfur, aromatics, oxygen and other physical parameters on particle size distribution, nanostructure, oxidation reactivity and chemical components was analyzed. This work aims to build the inherent relationship between particle size distribution, nanostructure, oxidative activity and chemical components and provides a scientific reference for the controlling of the atmospheric PM2.5 derived from motor vehicle emissions.
