摘　　要：对柴油机燃烧大豆生物柴油、0#柴油及乙醇与生物柴油的混合燃料的循环变动进行了对比分析,结果表明柴油机燃烧B100时,在小负荷工况出现较大的循环变动,中高负荷工况燃烧B100的各类COV都低于D100。在大豆生物柴油中混合乙醇作为燃料,对低负荷工况的循环变动有较大的影响,对中高负荷工况的循环变动影响不大。添加10%的乙醇既能降低柴油机燃烧的粗暴程度,又能使柴油机燃烧更为稳定。In this paper,the diesel engine combustion soybean bio-diesel,petroleum diesel 0 # and ethanol and bio-diesel blended fuel cycle changes through the contrast analysis of results showed that the diesel engine when burning B100,in the small load condition appear larger cyclical fluctuation,high load condition of burning B100 all kinds of COV below the D100. In soybean bio-diesel blend ethanol as a fuel,in low load condition of cyclic variations have larger,the influence of cyclic variations of high load condition. Add 10% ethanol can reduce the rough degree of diesel engine combustion and make diesel engine combustion is more stable.
