Abstract
The present invention provides an apparatus and method for controlling the fuel injection timing of a fuel injector in order to start an engine. The temperature of the engine is sensed and an engine temperature signal indicative of the temperature of actuating fluid used to actuate the injector is generated. A desired piston firing position is determined, and an injection command signal is generated, whose timing oscillates between a time range that is a function of said temperature and said desired piston firing position, to control the fuel injection timing.
