摘　　要：使用液化石油气(LPG)作为汽油机代用燃料,研究了改造后的LPG发动机的性能和排放特性。通过对LPG发动机经济性和排放指标的多目标规划,获取了LPG喷气量MAP图,依据发动机台架试验的结果表明,LPG发动机的动力性有所下降,其主要原因是发动机充气系数降低导致的,但经济性明显优于原机。LPG （Liquefied Petroleum Gas） was used as gasoline engine alternative fuel. The performance and emissions characteristic of improved LPG engine were researched. Based on multi - goal programming about LPG engine fuel economy characteristic and emissions level, LPG supply MAP was gotten. According to engine foundation experiments results,it can be verified that power characteristic of LPG engine is equal to the original and the main reason is that the coefficient of charge gas is lower than the original coefficient, fuel economy characteristic is superior to the original.

关 键 词：LPG发动机 代用燃料 动力性 经济性
