| 摘 要： | 本文介绍了一种利用微处理机自适应控制汽油机最佳点火正时的系统。该系统由一单板微处理机和一套全晶体管电子点火装置组成,反馈信号由汽油机转速传感器检取。汽油机稳定工况的台架试验和整车道路试验表明:用这种自适应控制点火系统与用机械分电器装置相比,汽油机的输出功率增大,油耗率下降,整车的动力性和燃油经济性得到提高。

| Abstract: | In this paper, an optimum spark timing control method for gasolineengine has been introduced.The control system is made up of a single-board microcomputer and an electronic ignition system. The feedback si-gnal is detected by a speed sensor. The result from steady state enginebench test and vehicle road test demonstrated that, using the adaptivespark timing control system, the power output of gasoline engine is in-creased and the fuel economy has been improved. |
