Ce基FBC催化柴油机碳烟氧化特性的试验
Experiment on characteristics of soot oxidation from diesel engine with Ce-based FBC fuel
摘要
Abstract
To investigate the effects of Ce-based fuel borne catalyst (FBC) on the catalytic oxidation of soot from diesel particles,naphthenic acid cerium solution was selected as FBC.Ce element was blended with diesel fuel with the ratios of 50,100,150 and 300 mg · kg-1(mass fraction) and marked as F50,F100,F150 and F300,respectively.The experiments on smoke emission,particle size,soot oxidation characteristic and diesel particulate filter (DPF) catalytic regeneration were conducted on a light-duty diesel engine with FBC fuels.The experimental results show that FBC fuels can improve the fuel economy and reduce the exhaust temperature and smoke emissions.The particle mass distribution moves to the small particle size,and the proportion of accumulation mode particles is increased with decreased proportion of coarse mode particles for engine with FBC fuels.The soot oxidation temperature is decreased with the increasing of FBC ratio,and the DPF regeneration temperature can be reduced with FBC fuels.关键词
