摘要： A control device for an internal combustion engine capable of controlling an intake-pipe pressure within a range which allows restartability to be ensured. A control device for an internal combustion engine includes: an idle-stop control section for restarting the engine in response to generation of a restart request; and an intake-air amount control section for setting a control amount of an intake system so that the intake air amount becomes zero when an intake-pipe pressure of the engine upon generation of the automatic stop request is higher than a predetermined pressure and setting the control amount of the intake system so that the intake air amount becomes larger than the amount upon generation of the automatic stop request, and then becomes zero when the intake-pipe pressure is lower than the predetermined pressure.
