基于南方摩托157FMI汽油发动机的点火提前角调节装置的研制

Research and Development of Advanced Ignition Angle Control System for Nanfang 157FMI Engine

基于南方摩托157FM I汽油发动机,现研究开发了一种以单片机为核心的、能控制发动机点火提前角的系统。该系统既能实现发动机点火提前角的计算与调节,还可以在发动机自主运行与该系统控制运行之间进行切换。该系统配合火花塞离子电流检测装置,可以实现对不同火花塞热值进行测试比较的目的。

This system uses a microcontroller as its primary component to control the advanced ignition angle of a 157FMI engine. It can compute and control the angle, and choose the work mode of the engine： working independently or controlled by the system. Associated with ion current detection device, this system can test and compare different kinds of spark plugs.
