Abstract: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.
