| 摘 要： | 对汽油机改装为天然气，汽油两用燃料发动机的供气系统在动力性、经济性及排放性能方面进行了比较分析，传统的混合器式天然气发动机对空燃比难以实现高精度的控制，采用电控缸外进气阀处多点喷射系统可以明显改善发动机经济性和排放性能，得到较高的功率输出。

| Abstract: | This paper analyzes comparatively gas supplying system of gas/gasoline dual fuel engine refitted from gasoline engine in power, economy and exhaust. It is difficult for the traditional mixed gas engine to realize high-precision control to air-fuel ratio. It is obvious to improve economy and exhaust by adopting multi-point injection in inlet valve out of electrical control cylinder and gain higher power output. |
