Abstract Motor vehicles, especially diesel vehicles, became one of main sources of atmospheric PM2.5, therefore it is very important to control emission of diesel engines by building the inherent relationship between fuel properties and exhaust particle. In this paper, several fuels of different physicochemical characteristics available for compression ignition engine, were studied by using SMPS, HRTEM, TGA, Thermal Optical Carbon Analyzer and GCMS, and the effect of fuel properties, such as sulfur, aromatics, oxygen and other physical parameters on particle size distribution, nanostructure, oxidation reactivity and chemical components was analyzed. The work aims to build the inherent relationship between particle size distribution, nanostructure, oxidative activity and chemical components and provides a scientific basis for the controlling of the atmospheric PM2.5 derived from motor vehicle emissions.
