ABSTRACT:
A fuel injection control method for an internal combustion engine in which asynchronous fuel injection can be carried out in accordance with the change in the number of engine rotations and throttle valve opening and asynchronously with the rotations of a crank shaft within a predetermined range of the number of engine rotations while inhibiting the asynchronous fuel injection when the number of engine rotations is not within the range, whereby the lean and over rich conditions of the air/fuel ratio which often occurred in the conventional method for controlling fuel injection can be prevented and acceleration with a good response can be realized.
