摘要： A fuel injector includes a fuel injector body defining a fuel inlet and at least one fuel outlet, a valve having a first valve state and a second valve state and an actuator for the valve. The fuel injector includes a biasing spring including a cylindrical rolled sheet having a first spring end, a second spring end and defining a longitudinal center axis. The cylindrical rolled sheet is configured to change in length to bias the actuator toward the first actuator position and includes a helical seam located between the first spring end and a second spring end which has a shape adapted to reduce non-uniformity in a spring constant via distributing stiffness about the longitudinal center axis.

摘要： A component includes a transmission arrangement for transmitting a force between an actuator and a control valve. The transmission arrangement includes a post that is associated with the actuator. The control valve is displaceable to an open position from a closed position when an opening force is applied to the control valve that is greater than a closing force provided to the control valve. The transmission arrangement is disposed in the component between the post and the control valve actuator and arranged to mechanically transmit by physical contact an actuator force from the post to the control valve when the post begins to travel towards the extended stroke position, and hydraulically amplify the actuator stroke between the post and the control valve when the post travels from the retracted stroke position to the extended stroke position.

摘要： An efficient control wave form is utilized to actuate the solenoids of a fuel system to reduce boost power/energy consumption. The solenoid is initially energized by applying a boost voltage from an electronic controller across a solenoid coil circuit. The electronic controller monitors the current level in the solenoid coil circuit, and changes to a reduced battery voltage when the current level in the solenoid coil circuit reaches a predetermined trigger current. The controller then maintains a pull-in current based upon battery voltage for a pull-in duration that initiates movement of the solenoid armature from an initial air gap position toward a final air gap position. After the pull-in duration, the current level is dropped to a hold in level for the remaining duration of the actuation event. The solenoid may be used for fuel injector control and/or pump control, such as to control fuel injection and pumping events respectively.
