Abstract

Under the plateau environment, the experiment was based on a GDI gasoline engine bench, and the collected particles were observed by high-resolution transmission electron microscope. The micro morphology and microstructure parameter changes of particles were analyzed under the working conditions of rotating speed of 1500r/min and load of 25%, 50%, 75% and 100%, respectively. The results showed that the basic carbon particles of GDI gasoline vehicle exhaust particles were of a quasi-circular core shell amorphous structure. The basic carbon particle diameter and carbon crystal length of GDI gasoline vehicle exhaust particulates are unimodal. Different loads do not affect the peak particle size, but only the size distribution proportion of microcrystals.
