ABSTRACT:
A fuel injection system includes a hydraulically-actuated electronically-controlled fuel injector having a needle valve member and an injector body that defines a fuel pressurization chamber that opens to a nozzle outlet. The needle valve member is positioned in the injector body and is moveable between an inject position at which the nozzle outlet is open, and a blocked position at which the nozzle outlet is blocked. A portion of the injector body adjacent the nozzle outlet is a mono gas valve member. The movement of the gas valve member controls one or both of the intake and exhaust portions of the engine cycle. The gas valve member is also hydraulically-actuated and electronically-controlled by the same hydraulic actuator that operates the fuel injector.
