    摘要： A method of operating an engine with dual fuel injection capabilities to address fuel rail over-pressure due to stagnating hot fuel is shown. The method comprises operating an engine cylinder with only port injection, and selectively activating and deactivating the second injector in response to a rail pressure increase of a fuel rail, the fuel rail coupled to the second injector, and deactivating the second injector in response to a rail pressure decrease of the fuel rail to a lower threshold determined based on engine operating conditions. In this way, degradation of the second injector may be reduced while maintaining a desired level of engine performance.

    摘要： A variable stroke direct injection (DI) fuel pump system for an engine includes a DI fuel pump having a stroke member and configured to pump a quantity of fuel based on a stroke of the stroke member. The system includes a variable fuel pump actuator assembly comprising an actuator member configured to actuate the stroke member, a control valve configured to control a flow of hydraulic fluid to the actuator member, and a hydraulic fluid pump configured to pump the hydraulic fluid and be actuated by one or more lobes of a camshaft. The system also includes an engine control unit (ECU) configured to control a variable stroke of the stroke member by controlling the control valve based on one or more operating parameters of the engine.

    摘要： It is equipped with an injector body 4z which has formed therein high-pressure paths 6az, 6bz, and 6cz through which high-pressure fuel flows to a spray hole and stores therein a piezo-actuator 2z (i.e., an opening/closing mechanism) and a back-pressure control mechanism 3z (i.e., an opening/closing mechanism) which open or close the spray hole, and a fuel pressure sensor 50z installed in the body 4z to measure the pressure of the high-pressure fuel. The body 4z has formed therein a branch path 6ez diverging from the high-pressure paths 6bz and 6cz to deliver the high-pressure fuel to the fuel pressure sensor 50z.

    摘要： A fuel pump and a method for controlling a fuel pump. At least two pumps run at a mutual phase displacement such that they are able to receive fuel during different periods of time. A control unit causes a valve, which is only settable in an open position and a closed position, to lead a desired amount of fuel to the respective pump. The control unit places the valve in the open position for a variable portion of the periods so that an individually controlled amount of fuel is led to the respective pump during those periods. Maintenance of good efficiency of the fuel pump and low noise emissions is thus made possible in operating situations where the fuel pump delivers a reduced amount of fuel.
