摘　　要：本文在高原环境(81kPa)下对4100QB-2柴油机燃用0#柴油、纯生物柴油的性能进行了实验研究。试验结果表明:柴油机燃用生物柴油的实测比油耗和小时耗油量比燃用柴油时平均分别高12.5%和13.2%,当量油耗与燃用柴油基本相当;热效率也基本不变;排气温度比燃用柴油平均低约6.3℃;噪声比燃用柴油时明显降低,平均低约1.74dB(A)。This article carried bench experimental study on the 4100QB-2 diesel engine fueled with 0^# diesel and biodiesel under the plateau environment （8 lkPa） , investigated the diesel engine performance when fueled with biodiesel. The result indicated that, when diesel engine fueled with the biodiesel, brake specific fuel consumption and the fuel consumption per hour were 12.5% and 13.2% higher; respectively, the equivalent oil consumption and thermal efficiency were similar to that when fueled with diesel. Exhaust gas temperature was about 6.3℃ lower on average. The noise level was 1.74dB（A） lower on average.
