摘　　要：文章分析了地沟油生物柴油的组成及其理化性能,并通过对比试验分析了地沟油生物柴油在柴油机上使用的排放性能。结果表明:地沟油生物柴油的主要成分是C16:0、C18:0、C18:1、C18:2的脂肪酸甲酯,并且其理化性能与矿物柴油基本相当;燃烧排放尾气中CO、HC和颗粒物含量有所降低,NOx含量有所升高,可完全替代矿物柴油长期使用。The paper analyzed the components of the waste oil biodiesel by gas chromatography. Comparative tests were made on a diesel engine fueled by the waste oil biodiesel and diesel in terms of the emission characteristics. The results showed that the basis of waste oil biodiesel is C16：0, C18：0, C18：1, C18：2 methyl ester. The physico-chemical properties of the waste oil biodiesel were almost the same to those of mineral oil. The function of diesel engine using the admixture fuel was improved as follows： the emissions of CO and HC and PM are decreased, and the mission of NOx was increased.
