Experimental Study on Soot Oxidation Characteristics of Diesel Engine with Ce-Based Fuel-Borne Catalyst Fuel
Publication: Journal of Energy Engineering
Volume 146, Issue 3
Abstract
In order to investigate the effects of a Ce-based fuel-borne catalyst (FBC) on the catalytic oxidation of soot particles from a diesel engine, a naphthenic acid cerium solution was selected as the FBC, which was blended with diesel fuel at four ratios. Experimental studies on the smoke emissions, particle size, soot oxidation characteristics, and diesel particulate filter (DPF) catalytic regeneration were conducted on a light-duty diesel engine fueled with FBC fuels. The experimental results show that FBC fuels can improve the fuel economy and reduce the exhaust gas temperature and smoke emissions. The particle mass distribution moves to the small particle size, the proportion of accumulation mode particles increase, and the proportion of the coarse mode particles decrease when the engine is fueled with FBC fuels. The soot oxidation temperature decreases with the FBC ratio increasing, and the DPF regeneration temperature can be reduced as diesel engine fueled with FBC.
