摘　　要：以Na OH为催化剂,利用甲醇与芸芥籽油发生脂化反应,制备了芸芥生物柴油.为了评价芸芥生物柴油的车用适应性,对比分析了0#石化柴油和芸芥生物柴油在密度、黏度、馏程、十六烷值和闪点等方面的理化特性差异,并针对不同混合比芸芥生物柴油的燃油消耗率和尾气(CO,CO2,HC,NOx,O2和碳烟)排放特性进行了台架试验.试验结果表明:芸芥生物柴油的理化特性完全满足车用燃油的要求;芸芥生物柴油的排放特性优于石化柴油,而燃油消耗率高于石化柴油;用混合比为B50的芸芥生物柴油替代0#石化柴油,可以在满足车辆动力性要求的前提下较好地改善发动机的排放性能.The Eruca-Sativa-Gars（ ESG） biodiesel was produced by the transesterification reaction between ESG and methyl alcohol with sodium carbonate as catalyst. The physical and chemical properties including density,viscosity,distillation range,cetane number and flash point of ESG biodiesel were compared with those of 0#diesel. The bed-test was conducted to analyze the emission performance of ESG biodiesel with different mixing ratios. The results of tests show that the ESG biodiesel can meet the fuel demands perfectly. The emission performance of ESG biodiesel is better than that of 0#with slightly higher diesel fuel consumption. The B50 biodiesel can substitute 0#diesel and modify the emission performance of engine.
