摘要
讨论了A/F闭环控制区域的特点,提出了初选点火提前角集合的概念。根据发动机台架试验结果,分析了电控汽油机工况对初选点火提前角集的影响,点火提前角对电控汽油机主要性能影响,介绍了基本点火提前角优化的一般原则。
The characteristic in the field of A/F closed loop control is discussed, and the conception of primary spark advance angle set is introduced. According to the result of engine test, the effect of operating mode of electronic controlled gasoline engine on primary spark advance angle set, and the effect of spark advance angle on the primary properties of electronic controlled gasoline engine are analyzed, the principle of optimization of basic spark advance angle is introduced.
