摘　　要：为了提高汽油机控制系统的性能及开发进度,节约成本,依据发动机的工作原理,利用MATLAB/SIMULINK工具建立了汽油机的计算机仿真模型,并进行了必要的验证,证明了该模型能有效的反映节气门开度与负载的变化。提出一种非线性的汽油机动态模型。由于该数学模型结构严谨且可调变量较少,所以可以建立针对于现有发动机的特定模型,或者建立一基于大量实验数据的发动机模型,且其精度可以与典型的发动机测功机精度相媲美。In order to improve the performance and development schedule of gasoline engine control system and save the cost,the computer simulation model for gasoline engine is established according to working principle of engine by applying MATLAB/SIMULINK.And necessary tests were carried out which proves that the model can reflect throttle percentage and the load change effectively.The model presented it is a nonlinear dynamic model for an gasoline engine.Since the model is so compact in mathematical structure,few variables are adjusted.Thus a typical model for the engine available might be established or an engine model basing on abundance test data might be established as well with accuracy matched with that of the dynamometer measurement of the engine.
