Abstract of the disclosure A fuel feed amount controlling method fur internal combustion engines comprising a step in which a required air flow volume and a time constant of the first-order lag until the injected fuel is actually sucked into the cylinder of the engine are estimated from the trodden amount of an accelerator pedal, the number of revolutions of the engine and a load to be applied to the engine and a step in which, when the accelerator pedal is trodden down, the fuel feed amount is determined in consideration of the time constant of the first-order lag of the fuel to the first-order lag of the air flow volume to be actually sucked into the cylinder, in order to prevent the uncomfort- able shock at the time of acceleration or deceleration and improve the accelerating and decelerating performances.
