Abstract:
A compression engine having an electronic control system, comprising:a hydraulically actuated electronic unit fuel injector mounted to the engine, capable of producing an injection event capable of having sub-events and connected to a source of actuating fluid;an electronic controller electrically connected to said hydraulically actuated electronic unit fuel injector;an engine speed sensor producing an engine speed signal responsive to a speed of said engine and communicating the engine speed signal to the controller;a throttle producing a desired speed signal being indicative of a desired speed of the engine and communicating the desired speed signal to the controller;a pressure sensor associated with the actuating fluid, electrically connected to the electronic controller, producing a pressure signal responsive to a pressure of the actuating fluid and communicating the pressure signal to the controller; andwherein said electronic controller delivers to said hydraulically actuated electronic unit fuel injector a fuel injection signal having one or more of a plurality of waveforms for controlling the sub-events and being generated from one or more of a plurality of fuel delivery maps as a function of the desired speed of the engine, the engine speed signal and the pressure signal.
