摘　　要：介绍利用数值仿真研究车用增压柴油机瞬态特性的意义,从柴油机的试验数据出发,在平均值模型的基础上,建立车用增压柴油机的动态模型,详细描述了涡轮增压器、柴油机及车用负载模型,并在Matlab/Simulink环境下给出了仿真模型结构框图和在两种瞬态工况下的仿真结果。This paper introduces the research significance of transient characteristic of turbocharged diesel engine in automobile. Based on the mean value model, a dynamic model of a vehicle turbocharged diesel engine is estabhshed coming from the test data of a diesel engine. The paper describes the model of turbocharger, diesel engine and vehicle load in detail and gives the simulation model architectures in the environment of Matlab/Simulink and two simulating results of transient process.
