摘要
发动机喷油时刻、配气正时、过量空气系数、点火时刻等发动机燃烧控制参数对增压直喷汽油机的缸内压力、缸内平均温度、燃烧放热率、排气颗粒物粒径及浓度分布等会造成不同程度的影响,对汽车尾气的排放产生一定的影响,通过对发动机各控制参数的调整,使发动机达到最佳的排放状态。
Engine combustion control parameters such as engine fuel injection timing,valve timing,excess air coefficient,and ignition timing affect the cylinder pressure,average cylinder temperature,combustion heat release rate,exhaust particle size and concentration distribution of turbocharged direct injection gasoline engines It will cause varying degrees of impact and have a certain impact on the emission of automobile exhaust.Through the adjustment of various control parameters of the engine,the engine can achieve the best emission state.
