| 摘 要： | 电喷汽油机使用CNG燃料后,动力性有所下降,针对此情况,提出以油门开度信号为控制信号,在小负荷工况下,燃用CNG;在大负荷工况下,改烧气为烧油的模式。通过电喷发动机台架试验证明,采用此燃烧模式在发动机大负荷工况下,动力性改善效果明显,燃料能耗有所下降。

| Abstract: | Being the factors of own characteristics,the EFI gasoline engine is rebuild into gasoline-CNG engine;the engine's power performance is reduced.According this,this paper puts toward the scheme:using the TPS(Throttle Position Sensor) signal as a control signal,the engine fuels with CNG in low load,and then the CNG supply is shut off,the gasoline is supplied for combustion in order to improve the engine's dynamic performance in high load.This scheme can obviously improve the power and economy of CNG/gasoline Engine. |
