摘要： A method of operating a fuel injector comprises the steps of applying a test waveform to a solenoid coil of the injector to cause a response by an armature assembly and measuring the response of the armature assembly while the test waveform is applied to the solenoid coil. A control waveform for the injector is developed as a function of the variation of the measured response of the armature from a selected operational characteristic. The developed control waveform is thereafter applied to the solenoid coil to cause the armature assembly to approach a nominal position.

摘要： An electronically-controlled fuel injector includes a pressurized fluid chamber that communicates high pressure fluid to first and second pressure control chambers. A direct-operated check moves between closed and open positions in response to a difference in fluid pressure in the first and second pressure control chambers. A first thermally pre-stressed bender actuator is used to operate a control valve that controls fluid communication between the fluid chamber and a fluid source. A second thermally pre-stressed bender actuator is used to operate a control valve that controls the fluid pressure in the first pressure control chamber to effectively control opening and closing of the check during portions of an injection sequence.

摘要： A fuel injector includes first and second valves and a solenoid including a solenoid coil and an armature assembly wherein the first and second valves are coupled to the armature assembly. A solenoid drive circuit is coupled to the solenoid coil and delivers a first current waveform portion to the solenoid coil at a first time to cause the armature assembly to operate the first valve without operating the second valve. A second current waveform portion different than the first current waveform portion is applied to the solenoid coil at a second time later than the first time to operate the second valve.

摘要： An engine is provided comprising an engine housing defining at housing and has a different portion associated with each engine cylinder. Each different portion of the engine auxiliary system has a first electrical actuator coupled to a first valve and a second electrical actuator coupled to a second valve which are wired in series. For example, a fuel injection system is provided with a first electrical actuator operably coupled to a fuel pressurizer and a second electrical actuator operably coupled to a direct control needle valve. The electrical actuators are wired in series on an electrical circuit. A method of controlling a portion of the engine auxiliary system is also provided which consists of actuating a first electrical actuator with a relatively low current and actuating a second electrical actuator with a relatively high current.
