ABSTRACT:
A method is provided for injecting fuel into an internal combustion engine. The method includes providing the engine with a plurality of fuel injectors, each including an electromechanical mechanism for receiving fuel under pressure via a fuel supply system and for injecting a measured amount of fuel into the engine in response to a command signal whose duration is indicative of the amount of fuel to be injected. The command signal is determined based upon a measured throttle position, engine speed and engine load. A resistance of a solenoid coil of the electromechanical mechanism is then calculated and the command signal is adjusted by incrementing or decrementing the command signal to compensate for variations in the measured resistance of the solenoid coil of electromechanical mechanism due to temperature variations.
