电控汽油喷射能有效地改善发动机的动力性、经济性以及排放指标，因而目前在国外已得到了广泛的应用，但在国内尚处于开始应用阶段，对电控汽油喷射发动机的感性认识较少。因此本文首先以试验研究为手段，充分显示出电控汽油喷射的优越性，然后从理论上分析电控汽油喷射改善发动机性能的因素和潜力。 Electronic gasoline injection can effectively improve the engine power, economy and emission targets, which has been widely used in foreign countries, but it is still in the domestic application stage, less aware of the sense of electric-controlled gasoline injection engine . Therefore, this paper, first of all, to test and study as a means to fully demonstrate the superiority of electronically controlled gasoline injection, and then theoretically analyzed the factors and potential of electronically controlled gasoline injection to improve engine performance.
