Abstract
A control system for controlling the flow of an actuating fluid to an accumulator, the accumulator serving the fuel injectors of an internal combustion engine, includes a controller being in communication with a plurality of engine related sensors. A variable output pump is in fluid communication with a source of actuating fluid and has at least two selectable output conditions, the pump being operably coupled to the controller, the controller acting to selectively port a portion of the actuating fluid to the accumulator in a first pump output condition and to vent the portion of the actuating fluid to a reservoir in a second pump output condition resulting in power saving. A fuel injection system and a method of control are also included.
