摘　　要：针对LPG／柴油双燃料发动机的动力性进行了研究。与燃用柴油相比，在相同热能消耗的情况下，掺烧液化石油气后，发动机的输出功率会增加，亦即发动机的动力性在掺气后会提高。随着掺比的增加，动力性上升，达到一定掺比时，动力性又开始下降，但仍高于燃用纯柴油时的动力性。试验结果表明，在掺比为20％～30％时，发动机的输出功率最高。Under the environment conditions, the power performance of the diesel oil/LPG dual fuel engine has been studied. The results indicate that under the condition of the same consumption of thermal energy, dual fuel engine＇s power performance is better than the diesel engine＇s. Along with rising up the ratio of LPG which burned by engine, the power performance increases, but it will decrease under established conditions which the ration of LPG is between 20% - 30%.
