Electronic control system and method for controlling the amount of fuel injected into an engine by a hydraulically operated electronically controlled fuel injection system

摘要

An apparatus and method for determining the current waveform of a fuel injection signal so as to consistently control the amount of fuel injected by an electronically controlled hydraulic actuator unit injector fuel system to an engine is disclosed. The apparatus and method varies the waveform of a fuel injection signal using equations or look-up maps and based on sensed operating parameters, which preferably include a desired speed of the engine or desired fuel quantity to be injected during an injection event, actuating fluid pressure and engine speed.
