电喷发动机燃用不同代用燃料的动力性能研究

Dynamic Performance of EFI Engine Using Substitute Fuels

对电喷发动机在全负荷速度特性下燃用93#汽油、乙醇汽油(E10、E20)、甲醇汽油(M15、M30)和液化石油气(LPG)时的动力性能进行了试验研究。结果表明:捷达电喷发动机在未作任何改造的情况下,燃用乙醇汽油(E10、E20)的动力性能同93#汽油相比稍有降低,但高于甲醇汽油(M15、M30);发动机改造成两用燃料系统后,燃用LPG的动力性能均低于其他燃料。

Dynamic performance of EFI engine experiments were carried out by using 93gasoline、M15、M30、E10、E20 and LPG under full load speed.The results showed that the unchanged engine that used Ethanol fuel(E10、E20)retained its high dynamics performance compared to the 93#gasoline,however,the engine used M15 and M30 was lower than the E10 and E20.The engine used LPG was the lowest than the other fuels when the engine was changed to the dual fuels system.
