ABSTRACT:
A control system for a fuel injector is disclosed. The control system has a valve element movable between a first position and a second position, an armature connected to the valve element, a solenoid configured to move the armature and connected valve element, and a controller in communication the solenoid. The controller is configured to energize the solenoid at a first current level to initiate movement of the valve element from the first position toward the second position, at a second current level less than the first current level during movement of the valve element from the first position toward the second position, at a third current level less than the second current level after the valve element has reached the second position, and at a fourth current level less than the third current level after the valve element has been in the second position for a predetermined period of time.
