摘要： The present invention is a fuel injection system having one or more fuel injectors (50) and an electronic control system therefore. The preferred fuel injector (50) has a double magnetic latching solenoid (24) three-way or four-way spool valve (120) that controls the flow of a working fluid that is used to control the discharge of fuel into the combustion chamber or intake manifold of an engine through the nozzle (72) of the injector (50). The control system provides actuating current pulses to each of the solenoids to actuate and latch the solenoids to effect initiation and termination of the injection. Disclosed are control systems that provide a snap action in one or both actuating directions of the valve.
