摘　　要：讨论基于Matlab/Simulink的非增压柴油机的非线性瞬态模型的建模方法.采用充排法建立了一个四缸非增压柴油机瞬态模型,进行了油门突变过程(负载固定)的仿真.利用实时工作间(RTW)将模型转化为通用实时代码,并利用外部模式(external)进行了仿真,加快了仿真的速度.模型不但可以用于ECU控制参数的在线标定,经简化后还可以用于复杂控制策略的开发.The modeling of non-linear non-turbocharger transient-state diesel engine was presented based on Matlab/Simulink. A four-cylinder non-turbocharger transient diesel engine model was developed. Simulation of the dynamic process of abrupt change in throttle (engine load held constant) was implemented. The model has been converted to generic real-time coder program, and simulated by the external method. The method can greatly cut the simulation time. The model can not only be used in parameter demarcation for ECU, but also in the development of complicated control strategies.
