摘要
列举了发动机使用外特性和万有特性建模的几种数值计算方法,并结合某种类型的发动机对各种建模结果进行了分析比较,认为运用最小二乘法建立的发动机特性数学模型具有较高的拟合精度,而且计算方便。
The engine performance model is the base on the simulation of dynamics and economic in automobiles. The accuracy of the model has great influence on the results. Some mathematic methods about modeling engine performances are presented in this paper, and analyses and comparison of the results calculated for specific engine are also made. The best modeling method is given in the end.
