发动机特性计算模型的应用探讨

Approach on Application of Computing Model to Engine Performance

发动机特性模型的建立是进行车辆动力性和燃料经济性模拟计算的基础,本文利用拟合法、综合法和类比法描述了发动机使用特性的数学模型,并进行了比较。研究结果表明,本文提出的类比法简单可靠,计算精度符合要求。

Modeling engine performance is the foundation for imitating dynamic and economic performances of automobile. The mathematical model of engine performance is described in this papert by means of the copying, combining and contrasting mothed with their results compared. It is shown that contrasting method proposed is more simple and reliable, and the computational accuracy is satisfatory.
