ABSTRACT:
In an internal combustion engine, a base fuel amount is calculated, and a synchronous fuel amount to be supplied to the engine is calculated in accordance with the base fuel amount. Further, an air-fuel ratio deviation is calculated when the engine is in an acceleration state, and an asynchronous fuel amount is calculated for the transition of the engine from a fuel cut-off state to a fuel cut-off recovery state in accordance with the calculated air-fuel ratio deviation.
