たことを特徴とするエンジンの燃料制御装置。 Engine fuel control that calculates the basic fuel injection amount based on the output of an air flow meter, and when the calculated value is smaller than a preset lower limit value, the lower limit value is used as the basic fuel injection amount. The apparatus comprises: an increase means for increasing the fuel injection amount according to the operating condition; and an increase restriction means for restricting the increase correction by the increase means when the lower limit value is the basic fuel injection amount. An engine fuel control device characterized by:
