ABSTRACT:
In an internal combustion engine coupled with a supercharger, a basic fuel supply amount is calculated on the basis of an intake air flow rate measured by a hot wire type air flow meter and an engine speed. During an engine decelerating condition, the maximum value (limit value) of the basic fuel supply amount is set on the basis of an open area of an induction system, which is based on a degree of opening of a throttle valve, and the engine speed. The basic fuel supply amount based on the measured value of the air flow meter is limited and can not exceed a value.
