点火提前角的仿真计算

Simulating Calculation of Preignition Angle

本文以发动机的准维燃烧模型为依据,以一条实验法则为理论基础,介绍了汽油机最佳点火提前角初始MAP图的确定和计算方法。从程序运行结果来看,点火提前角的值以及点火提前角随转速和负荷的变化规律与实际情况基本相符,表明仿真运算结果基本正确。

This paper introduces the ascertaining and calculation ways of gasoline engine optimal preignition angle＇s original MAP according to engine＇s standard dimension combustion model and an experimental principle. The program run result shows that the preignition angle＇s value and its changing rule along with rotate speed and charge match with the practical ones. The simulation result is basic ally correct.
