Abstract
In a multicylinder internal combustion engine having fuel injection valves for respective cylinders, an improved fuel injection control system includes a first device for detecting the amount of air fed to each cylinder and a second device for calculating a basic fuel injection amount at given intervals on the basis of the detected quantity of state, for weighting the basic fuel injection amount at the given intervals to obtain a substantial fuel injection amount which corresponds to the amount of air fed to the cylinder, and for correcting the substantial fuel injection amount on the basis of a given rate of a variation between the basic fuel injection amount and the substantial fuel injection amount thereby to obtain a final fuel injection amount. The control system also includes a third device for driving each of the injection valves on the basis of the final fuel injection amount.
