Abstract
In a control device for an internal combustion engine, when a fuel-supply cutoff process ends and fuel injection restarts, an increase ratio based on which a base injection amount is increased is set such that the increase ratio when a duration of the fuel-supply cutoff process is long is higher than the increase ratio when a duration of the fuel-supply cutoff process is short. In addition, the increase ratio is decreased with a lapse of time after fuel injection restarts. Further, a decrease rate that is an amount by which the increase ratio is decreased within a prescribed period of time is set such that the decrease rate in the case where the duration of the fuel-supply cutoff process is long is higher than the decrease rate in the case where the duration of the fuel-supply cutoff process is short.
