摘　　要：通过分子蒸馏技术从菜籽油脱臭馏出物中制备生物柴油,并通过对比试验,研究了柴油机燃烧生物柴油和普通柴油对发动机经济性和排放特性的影响。研究结果表明,脱臭馏出物中制备的生物柴油与普通的0#柴油性质相似,脂肪酸甲酯质量分数在90%以上。在生物柴油的排放中,除CO2排放和耗油率相对升高,CO2排放增加幅度达到20%左右;CO,CH和碳烟都相对降低,烟度和CH最高降幅分别达到54%和88%;NOx排放在高载荷阶段体积分数上升。Biodiesel was prepared from rapeseed oil deodorizer distillate by molecular distillation. The effect ot biodiesel and conventional diesel 0^# on fuel consumption and emission characteristics of diesel engine was studied via comparison test. It shows that the properties of biodiesel are very close to diesel fuel and the mass fraction of fatty acid methyl ester is above 90%. In bio-diesel emissions, except for a relatively increasing of CO2 and fuel consumption with CO2 emission increasing by 20% , CO and CH emission and smoke amount of mixture of biodiesel and diesel all relatively decrease, with the max. falling margin of 54% and 88% respectively; the volumetric fraction of NO emission rises under the condition of high-load stage.
