Abstract
A feedback control method for electronically controlling the fuel injection for an internal combustion engine, which is characterized by detecting the actual nozzle needle lift and actual injection pressure of a fuel injection valve to arithmetically calculate an actual fuel injection quantity from the detected values of nozzle needle lift and injection pressure by means of electronic computer means, detecting the values of factors indicative of the operating condition of the engine such as engine speed and engine load to arithmetically calculate a required fuel injection quantity from the detected values of the above factors by means of the electronic computer means, and correcting the calculated required injection quantity with reference to the calculated actual injection quantity.
