Abstract
In a fuel injection controlling method for an internal combustion engine having the hot were air flow meter and the valve opening pulse generating means for a fuel increment independently of the basic valve opening pulse generating means for causing the injector to inject fuel normally during the normal condition, the valve opening pulse for a fuel increment has a duration dependent on at least one of selected from variations in the air intake volume per unit time, a closing signal of the idle switch for the throttle valve, a signal indicating the number of revolutions of the engine, etc., independently of the duration of the basic valve opening pulse. The acceleration adjustment is adjusted the fuel increment in accordance with the valve opening pulse for a fuel increment. It is possible to obtain optimum acceleration by varying the adjustment depending on conditions for interrupt adjustment during acceleration. By applying the judgment of conditions for adjustment after fuel reduction for deceleration, it has become possible to acceleration matching between the state after deceleration and the state after normal operation.
