Abstract
A method of controlling fuel supply during beginning 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 valve opening to a detected amount or value of throttle valve opening when it is detected that the throttle valve 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. Further methods of controlling fuel supply during acceleration are also provided wherein the additional correctional increase is a function of engine load or acceleration rather than throttle va…
