Abstract
An apparatus and method for varying the current levels of a fuel injection signal used in connection with an electronically controlled hydraulic actuator unit injector fuel system is disclosed. The apparatus and method varies the current level of the fuel injection signal delivered to the unit injector based on sensed engine parameters, which preferably include a sensed pressure of hydraulic actuating fluid and a sensed temperature of the engine.
