摘　　要：本文讨论了排气放气阀系统及汽油机增压压力控制的重要性,为了与MK14软件结合进行汽油机增压模拟计算,提出放气阀特性描述方法和边界模型,并编制了排气和气阀子程序.对492QA汽油机增压进行了计算,并作了试验验证.This paper discusses the exhaust waste gate system and the importance of boost pressure control in turbocharged gasoline engines. For computer simulation of turbocharged gasoline engines in conjunotion with the Mark 14 program, a method is presented to represent the waste gate characteristics and boundary conditions in compiling additional subroutines for the exhaust waste gate system. Subsequent simulation has been carried out on the turbocharged gasoline engine 492QA and the results agree qualitatively with that of engine performance tests.
