| 摘 要： | 实验研究了一款小型汽油机在不同负荷下,使用不同EGR率时,其动力性、经济性和NOx排放特性的变化规律,确定了各个工况下发动机最佳EGR率,得出在较大负荷下,EGR阀开度为30°时可以使动力性、经济性在变化不大的情况下,NO降低60%以上。

| Abstract: | The technology of exhaust gas recirculation（EGR） was studied and applied on a light gasoline engine in order to reduce its nitrogen oxides（NOx） emission.When gasoline engine operated under different operational conditions,the influences of different EGR rates on the engine performance and emissions were investigated,the optimization rule of EGR rates was constructed,the optimum EGR rates were concluded and labeled for different operational conditions.Under most conditions,when the opening degree of EGR valve is 30 degree,the characteristic is maintained well and the NOx reduction is more than 60%. |
