摘　　要：L497是一种霍尔信号触发的高性能点火控制器,它广泛应用于汽车的点火系。分析了L497在低转速发动机下存在的两大问题:功耗大;闭合角控制的不稳定性。提出通过改变L497集成块的外围电路和外围元件参数解决了上述问题,并将它很好地应用于汽油辛烷值测定机的点火系。L497 is an integrated electronic ignition controller using Hall effect sensors,which is widely used in the ignition systems of a car.Two problems of L497,high loss of power,instability of dwell angle controlling may occur when applied in the low engine speed are analysed in this paper.The above problems are solved by modifying its peripheral circuit and the value of peripheral component and it is found its application to the ignition system of gasoline octane tester.
