Abstract In order to reveal the effects of diesel oxidation catalyst (DOC)on size distribution and components of particulate matter emitted from diesel-biodiesel dual fuel (B0, B10, B20), an experimental study was carried on a diesel engine. Particle samples from different size grades were got from MOUDI and distribution of the mass concentration was obtained by weighting the particle. Beside, thermogravimetric characteristics of particle and varieties of components were analyzed by using thermogravimetric analyzer. Results showed that with the increase of biodiesel percentage, the mass concentration of every size grade decrease and it was especially obvious when B20was used. The mass concentration peak value of particulate matter emitted from three fuels all range from 0.18μm to 0.32μm. In addition, with the increasement of biodiesel percentage, the mass concentration of SOF increased while mineral salt and soot decreased. When DOC was used, the mass concentration of particulate matter decreased and the convert efficiency was not evident for particle above 1μm. The convert efficiency of accumulation state particles higher than that of coarse particle. Moreover, with the increasing of speed, the mass concentration of SOF decreased, while H₂O, soot and mineral salt increased.

Key words： DOC biodiesel particulate matter size distribution components
