摘　　要：为了更好地评价柴油机燃用生物柴油的经济性,分析了生物柴油和0#石化柴油的理化性质,分别对生物柴油的体积分数为0.2,0.5,1的B20、B50、B100 3种燃料和0#柴油在495Q3柴油机上进行了试验。试验结果显示燃用3种燃料的燃油消耗率比0#柴油在中小负荷时平均增加5.30%,9.65%,19.04%,大负荷时平均增加2.86%,4.75%,9.64%;能量等值折合油耗率在中小负荷时平均增加2.65%,2.63%,5.74%,大负荷时平均降低0.26%,1.97%,4.80%。In order to better evaluate the economy of bio-diesel for diesel engine burning, physical and chemical properties of the bio-diesel and 0# diesel are analyzed. The fuel B20, B50, B100 and 0# diesel are tested in 495Q3. The results showed that the rate of fuel consumption increased about 5.30% , 9.65% , 19.04% when engine fueled three fuel to fueled 0# diesel in the low-load, and increased about 2.86% , 4. 75% , 9.64% in greater load; the rate of fuel consumption of energy equal value increased about 2.65% , 2.63% , 5.74% in the low-load, reduced about 0. 26% , 1.97% , 4.80% in greater load.
