汽油/LPG两用燃料发动机性能试验研究

Research on Performance Test of Gasoline/LPG Bi-fuel Powered Engine

介绍了一种可用于电喷发动机的LPG改装系统,系统设置了燃料转换开关来控制燃料的转换。该改装系统应用于捷达发动机,测量了发动机分别使用汽油和LPG的输出功率和排放情况,结果表明在燃烧汽油时性能没有变化,使用LPG时动力性稍有下降,排放有明显改善。

LPG hi-fuel system placed in the EFI engine is introduced in this article, the fuel change-over switch in the LPG system is to control the fuel conversion. LPG bi-fuel system equipped in Jetta engine is given as an example, its power output and emission are measured when use of petrol and LPG respectively. The performance of the engine has not been changed as combustion of petrol, but a slight decline has been indicated and the emissions have been significantly improved with LPG system.
