Abstract
A control device is for an internal combustion engine including a throttle valve and a variable valve mechanism, and configured to be operated at a prescribed target air-fuel ratio and capable of restarting from an intermittent stop. The control device includes an electronic control unit configured to start the internal combustion engine after starting an intake air amount reduction control, when a fuel injection amount equal to or larger than a prescribed amount is required and an intermittent stop time is equal to or longer than a prescribed time in a case of the restart from the intermittent stop. The intermittent stop time is a stop time from an immediately preceding intermittent stop to a current restart of the internal combustion engine. The intake air amount reduction control is a control of reducing the intake air amount by operating the variable valve mechanism with the throttle valve kept fully closed.
