摘要
论述了现代GDI发动机在电子控制策略(包括混合气的制备,扭矩的调节,喷油正时的选择)、燃油喷射系统及燃烧系统的设计、缸内气流运动的组织以及燃烧排放等几个方面目前所取得的进展和存在的问题,并对目前国外典型的采用缸内直喷稀薄燃烧系统的发动机进行了分析,指出了GDI及其稀燃技术未来的发展趋势。
A summary is given to domestic research of modern GDI engines on the strategy of electrically control (includethe preparation of mixed gas, the adjustment of torque, the choice of the timing of fuel injection),the design of fuel injectionsystem and combustion system, the form of gas flow movement in cylinder and emission, regarding to their current situationin development and problem.Meanwhile the analysis of abroad typical engine using fuel direct injection and lean mixturecombustion system is also given. At last the author indicates the development trends of GDI and lean mixture combustiontechnique in the future.
