Particle is the main pollutant in diesel engine exhaust, which seriously endangers human health and the atm. environment. The use of alc. fuels in diesel engines can effectively reduce particle emissions, but alc. fuels with different carbon chain lengths will affect the generation process of particles, which in turn changes the physicochem. properties and oxidation characteristics of the particles. Therefore, it is particularly important to study the properties of particle emitted by diesel engines fueling alc. fuels with different carbon chain lengths. The physicochem. properties of soot emitted from com. diesel engines were studied by thermogravimetric analyzer, HRTEM (high-resolution TEM), and XPS (XPS) in this paper, resp. The diesel engine used alc.-diesel blends of different carbon chain lengths with the same oxygen content as fuels, such as methanol/diesel blend (M10), n-butanol/diesel blend (NB25), and n-octanol/diesel blend (NO45), and pure diesel fuel was used as a reference The use of alcs. reduced the fractal dimension (Df) of particles, and the NB25 particles had the smallest Df. Moreover, the particles of blended fuels had smaller primary particle diameter (dp) compared to pure diesel. However, with the use of short-chain to long-chain alcs., an increasing tendency of dp was observed In terms of the nanostructure, as the use of short-chain to long-chain alcs., the La (fringe length) increased, both the d (fringe separation distance) and Tf (fringe tortuosity) reduced, which was not favorable for the oxidation of the particles. In addition, in terms of oxygenated surface functional groups (SFGs), the C=O group occupied a higher proportion in most working conditions relative to the groups of C-O and COO. Further anal. showed that the dp and nanostructure had more influence on the oxidation behavior of soot than Df and oxygenated SFGs.
