ABSTRACT:
An internal combustion engine fuel injection system of the type having a plurality of fuel injection valves which are operated so that continuously pressurized fuel is intermittently supplied to each of the injectors by a distributor. The fuel injection control system further includes a novel flow control circuit for operating each of the fuel injectors, the flow control circuit being a bidirectional flow control circuit which controls the flow of fluid to and from the actuator of the fuel injector. The flow of fluid in one direction through the flow control circuit controls the rate of closing of the fuel injection nozzle while the flow of fluid in the opposite direction through the flow control circuit controls the rate of opening of the fuel injection nozzle.
