ABSTRACT:
A fuel injection control apparatus for an internal combustion engine has a controller, which includes a microprocessor for executing a predetermined processing in response to fundamental parameters representing the operational condition of the engine, produces a basic fuel injection pulse on the basis of a suction air quantity and a rotational speed of the engine and corrects the basic fuel injection pulse in accordance with the degree of acceleration or deceleration required, thereby to provide a fuel injection pulse applied to a fuel injector. The microprocessor is provided with membership functions varying with respect to acceleration or deceleration and determines a correction coefficient for correcting the basic fuel injection pulse on the basis of the degree of acceleration or deceleration required in accordance with a fuzzy reasoning using the membership functions.
