摘　　要：在分析了点火提前的机械控制和电子控制两种方法的特点以及电子控制方法中的自适应控制的研究现状的基础上，提出了在常规机械控制的汽油机上仅利用分电器输出的点火信号进行点火提前自适应控制的理论和方法，并进行了该理论方法可行性实验研究。试验研究结果表明：所提出的控制理论和方法是切实可行和有效的，点火提前自适应控制使发动机的性能得到提高。On the basis of analyzing features of both mechanical and electronic control for ignition advance and researching on the present situation of adaptive control of the electronic control methods,the article raises the theory and method of adaptive control for ignition advance which only makes use of ignition signal output by distributor used in the conventional mechanical controlled gasoline engine,moreover it carries on the feasible experimental research with the theory and methods.The results of experimental research show that the raised control theory and methods are feasible and effective as well as the engine performance can be improved by adaptive control of ignition advance .
