摘　　要：利用GT-Power进行建模,探究独立式与一体式两种电增压方式对米勒循环柴油机性能的影响。仿真结果表明:两种电增压都可以拓宽米勒循环的应用范围,一体式电增压适用于过量空气系数高的工况,独立式电增压适用于过量空气系数低的工况。与高转速大进气量工况相比,低转速小进气量工况使用电增压能获得更好的增压效果。GT-Power was used for modeling to explore the influence of independent electric supercharging method and integrated electric supercharging method on the performance of Miller cycle diesel engines.The simulation results show that both electric boosters can broaden the application range of the Miller cycle.The integrated electric booster is suitable for working conditions with high excess air coefficients,and the independent electric booster is suitable for working conditions with low excess air coefficients.Compared with high speed and large intake air volume,the use of electric booster in condition with low speed and small intake air volume can achieve better supercharging effect.
