ABSTRACT A method of controlling fuel supply during starting acceleration and acceleration after the interruption of fuel supply of an internal combustion engine is provided wherein a basic fuel supply amount which is determined in accordance with stable operating conditions of the engine is increased when it is detected that the throttle valve of the engine is opened from its almost closed position. The method comprises the steps of determining a reference value by adding a predetermined value of the throttle calve opening to a detected amount or value of throttle valve opening when it is detected that the throttle calve is opened from its almost closed position. The basic fuel supply amount is additionally correctionally increased if the correctional increase of the basic fuel supply amount, which was initiated upon detection of opening of the throttle valve, has not yet reached an end when the detected value of the opening of the throttle valve reaches the throttle valve opening reference value. A further method of controlling the fuel supply during acceleration of an internal combustion engine is provided, wherein a basic fuel supply amount, which is determined in response to a normal operating condition of the engine, is correctionally increased when a differential value of a detected value, indicated of a load on the engine, exceeds a predetermined value. The method comprises the steps of adding a predetermined value to the detected value indicative of the engine load (hereinafter the "engine load") to provide a reference value of the engine load when the differential value of the engine load exceeds the predetermined value, and additionally, increasing the correctionally increased basic fuel supply amount if the correctional increase of the basic fuel supply amount, which was started when the differential value of the engine load exceeded the predetermined value, has not ended when the detected value of the engine load reaches the reference value.
