针对当前市售汽油机的供油时刻、供油量、点火提前角等参数无法调整、不利于实践教学的问题，开发了一款实验用汽油发动机燃油喷射、点火系统。该系统基于单缸汽油机设计，以飞思卡尔8位单片机MC9S08DZ60为主芯片，完成了相应传感器信号的处理电路，开发了相应的燃油喷射及点火系统的硬件电路系统，并且完成了相应的上位机交互界面的开发。实验表明，该系统可以实现喷油量、喷油时刻及点火时刻等参数的调整，对学生掌握汽油机电控系统的组成和功能起到积极作用。

Today the injected fuel , injection timing and ignition advance angle can not be adjusted for commercially available gasoline ,which is not suitable for practice teaching ,so a fuel injection and ignition system is developed for experiment gasoline engines . The system is based on Freescale 8 bit single chip MC9S08DZ60 for a single-cylinder gasoline engine and the process circuit for sensors ,a fuel injection and ignition system is developed based on it .Then the interface for users also is developed based on VC + +platform . The experiments show that the system can achieve the injection timing and ignition timing adjustment and it plays an active role for the students to master the composition and function of the electrical fuel control system (EFI) .
