摘要
液化石油气（ＬＰＧ）应用于汽油机上的怠速排放对比、动力性恢复研究和燃烧特性对比的试验结果表明：燃用ＬＰＧ时，ＣＯ和ＨＣ排放显著降低；采用气体加浓、汽油加浓、点火提前角优化等方法，燃用ＬＰＧ的动力性可得到明显地恢复；与燃用汽油相比，燃用ＬＰＧ具有较小的着火延迟期。
On the application of Liquefied Petroleum Gas (LPG) to gasoline engines, this paper studies the comparison of emission pollution, the resumption of output and the comparison of combustion characteristics. Fueled with LPG, CO and HC are decreased largely. When the methods, such as riching gas or gasoline mixture and optimizing ignition advanced angle, are applied, the output of a LPG engine is resumed obviously. The ignition delay period, the main combustion period and cycle to cycle variation are smaller fueled with LPG than fueled with gasoline.
