摘　　要：本文描述了一种直接利用火花塞电极作为传感器检测南方摩托车发动机早燃的方法,作者在文章中详细分析及讨论了离子电流的产生机理。为了检测南方摩托车发动机早燃现象,利用其气缸内燃烧时产生大量的离子电流信号所包含的丰富燃烧信息,对其火花塞正常点火和炽热点火离子电流显示的波形进行研究分析,从而确定是否发生早燃。实际应用结果表明,这种检测方法具有较大的实际价值。This paper describes a system for preignition in motorcycle engine using spark plus as a detecting probe,the author carries out researches on a method how the ionic current corns into being. In order to examine the south motorcycle engine preignition phenomenon, using the rich burning information of the massive ions which are produced when the air cylinder is burnt, Through analyzing the wave form difference between lighting a free normally and firing early, it can be determined whether preignition occurs or not. The actual application result indicates that the examination method has a greater practical value.
