ABSTRACT:
There is a method for controlling the fuel supply of an internal combustion engine having a throttle valve in the intake air system. It is detected that an angular position of a crankshaft of the engine coincides with a predetermined crankshaft angular position. Whenever this coincidence is detected, the pressure in the intake air passage downstream of the throttle valve and the engine rotating speed or the value of the inverse number thereof is detected on the basis of the interval between the detections of the crankshaft angular position. The reference basic fuel supply amount which is to be supplied to the engine is determined in accordance with the present detection value P.sub.BAn of the pressure in the intake air passage. The present reference value M.sub.eAVEn having a predetermined functional relationship to the present detection value M.sub.en and previous reference value M.sub.eAVE(n-1) of the engine speed or of the value in inverse proportion thereof is set. The correction fuel supply amount is decided on the basis of the present reference value M.sub.eAVEn and is added to the basic fuel supply amount. Then the injection amount of fuel commensurate with the result of this addition is supplied to the engine. Thus, the driveability of the engine is improved.
