ABSTRACT:
In a fuel injection apparatus comprising an actuator for driving a member for controlling the amount of fuel injected, a computing circuit for computing a first signal representing an optimum amount of fuel injected on the basis of the engine operation conditions and a signal generator for generating a second signal representing the amount of fuel injected from an injection nozzle, the signal generator has a detector for generating a position signal indicative of the position of needle valve of the injection nozzle at the instant of injection, a converting circuit for converting the position signal into an open area signal representing an open area of the injection nozzle and a computing circuit for computing a signal indicative of the actual amount of fuel injected on the basis of the open area signal.
