Abstract:
A method for injecting fuel into an internal combustion engine, comprising the steps of:providing said engine with a plurality of fuel injectors, each of said injectors including an electromechanical injection assembly for receiving fuel under pressure via a fuel supply system and for injecting a measured amount of fuel into said engine in response to a command signal whose duration is indicative of the amount of fuel to be injected;determining a command signal for said fuel injectors based upon a measured engine speed and engine load;measuring a resistance of a solenoid coil of said electromechanical injection assembly in accordance with a fly back pulse duration; andadjusting said command signal by incrementing or decrementing said command signal to compensate for variations in the measured resistance of said solenoid coil of said electromechanical injection assembly due to temperature variations.
