摘　　要：首先根据内燃机进排气系统一维非定常流动模拟计算"有限体积法-总变差减少"程序,建立了三级大小相继涡轮增压系统柴油机模拟计算程序。利用该模拟计算程序,在切换点调整时,对三级大小相继增压系统进行研究。研究表明:与切换点固定的柴油机相比,选用可变切换点的三级大小相继涡轮增压系统的柴油机,更能改善各工况下发动机性能。According to the FVM-TVD simulating program for one-dimensional unsteady flow in inlet and outlet manifold of ICE,the simulating computation program of three staged sequential turbocharging system is built.According to the simulating computation program,three staged sequential turbocharging system is studied on diesel engine when shifting points are adjusted.The result demonstrates that compared with the constant shifting point on the diesel engine,three staged sequential turbocharging system of the variable shifting points will improve the performance of diesel engines on different loads.
