一款提高喷油器喷射品质的驱动电路

A Style of Driving Circuit to Improve the Injection Quality of Fuel Injector

为抑制感生电动势对驱动元件及电源的影响,续流电路成为感性负载驱动电路的重要组成部分,合理控制续流可以在一定范围内改善感性负载的工作特性。针对改装用燃气喷射电磁阀动作响应性能差的特点,其驱动电路采用了续流控制方法。

The freewheeling circuit is one of the important components in inductive load driving circuit to reduce the effect of induced electromotive force on driving elements and power. A driving circuit adopts the follow current control according to the former gas injection solenoid valve in poor action response.
