摘要： A fuel injector includes an injector body that defines a nozzle outlet. A needle valve member is mounted in the injector body and moveable a lift distance between an open position in which the nozzle outlet is open, and a closed position in which the nozzle outlet is blocked. A piezoelectric actuator is mounted in the injector body and is moveable a piezo distance between an off position and an on position. A coupling linkage interconnects the needle valve member to the piezoelectric actuator such that a movement of the piezoelectric actuator is multiplied into a larger movement of the needle valve member.

摘要： The present invention relates to fuel injectors having the ability to inject fuel at multiple pressures during an injection event. Traditional fuel injectors used in common rail fuel injection systems and unit pump fuel injection systems typically did not have the ability to inject fuel at multiple pressures during an injection event. However, engineers have learned that increased control over an injection event can lead to improved emissions by the fuel injectors. Therefore, the present invention utilizes an electronically controlled valve member that can direct. the flow of fuel through a fuel injector during an injection event between a relatively restricted passageway and a relatively unrestricted passageway. The present invention finds particular application in both common rail fuel injection systems and electronic unit pump fuel injection systems used in diesel engines.

摘要： A closed needle injector assembly is provided which effectively permits low fueling quantity control in short duration injections and pilot quantity control in longer duration events without compromising energy efficiency, maximum fuel delivery rates nor requiring increased operating pressures. The closed needle injector assembly includes first and second needle valve elements and a throttle passage formed in the second needle valve element to restrict fuel flow through an injector orifice. The second needle valve element is telescopingly received within the first needle valve element. Respective control volumes and one or more injection control valves are used to control the movement of the needle valve elements. Operation of the assembly results in movement of the first needle valve element to an open position for throttling fuel flow through the throttle passage followed by subsequent lifting of the second needle valve element for longer duration injections.

摘要： A common rail fuel injection device for ensuring the main injection start timing by correcting a pulse start time of a main injection command pulse, in accordance with the length of an interval between the main injection and a pilot injection. The recovery degree of current energy for driving an injector varies in accordance with the length of the interval Tint from a pilot injection end (T4) to an main injection start time (T6), and this variation affects the main injection start time. By taking a longer value for an injector drive delay time (Td) as the length of the interval Tint is shorter, a pulse start time (T5) of a main injection command pulse CPm for performing the main injection is corrected as a more advanced timing, and hence the fuel injection for the main injection can be performed at a prescribed injection start timing.
