LPG-SGI系统发动机试验研究

The Experimental Investigation of the LPG-SGI System Engine

研究了电喷车用LPG顺序喷射系统(即SGI系统)的有关特性,了解LPG-SGI系统在多种稳定转速和负荷下的发动机性能及排放特性,并与原发动机使用汽油燃料进行对比。装有LPG-SGI系统时代超人样车的排放满足国家现在实施的欧洲Ⅰ号排放法规的要求。

Along with the electronically controlled fuel injection system replacing the carburetor in cars gradually,that the investigation of LPG used to this type of car becomes a rather urgent need. The experiment about the performance parameters of the LPG-SGI system has been carried out. It is shown that under various steady speeds and loads the engine and emission performance of the sample car with LPG-SGI system are better than that of the original gasoline fuelled car,and can meet the Euro:! exhaust emission standards which has been executed in China.
