ABSTRACT:
A system and a method for controlling fuel supply to an internal combustion engine are disclosed in which excessive supply of fuel to the engine is effectively prevented in a most reliable manner particularly at the time of engine deceleration. To this end, a reduction in the amount of intake air sucked into an engine per intake stroke is sensed, and the amount of fuel supplied to the engine is reduced when there is a reduction in the intake air amount sucked into engine per intake stroke. The amount of reduction in the fuel supply is changed in accordance with at least one of the number of revolutions per minute of the engine and the amount of intake air sucked into the engine per intake stroke.
