<P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine that can maintain the intake pipe pressure by suppressing fluctuations in the engine rotational speed after generation of an automatic stop request and controlling an intake pipe pressure to a range for ensuring restartability of the engine. <P>SOLUTION: The control device of an internal combustion engine includes: an idle-stop control part for stopping fuel injection to stop the internal combustion engine in response to generation of an automatic stop request, and restarting the engine in response to generation of a restart request; and an intake-air amount control part which when an intake-pipe pressure of the engine upon generation of the automatic stop request is higher than a predetermined pressure, sets a control amount of an intake system so that the intake air amount becomes zero, the intake system controlling an intake volume of the internal combustion engine and when the intake-pipe pressure is lower than the predetermined pressure, sets 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 until the intake-pipe pressure becomes the predetermined pressure, and so that the intake air amount then becomes zero. <P>COPYRIGHT: (C)2013,JPO&INPIT |
