摘　　要：针对LPG/柴油机双燃料发动机的经济性进行了研究.随掺比的增加,当量比油耗先降后升,最低当量比油耗在20%～40%的掺比范围内取得;随着掺比的增加,排气温度降低,过量空气系数和充气效率减小.Research has been done on economic performance of LPG/diesel oil dual fuel engines. The test results indicate that when the ratio of LPG is rising, the equivalent unit consumer of fuel decreases first and increases afterwards. The least equivalent unit consumer of fuel is reached when the ratio of LPG is between 20%-40%. Moreover, with the rising of the ratio of LPG, the exhaust temperature, excess air coefficient and efficiency of air inflation decrease.
