Abstract

A control device for an internal combustion engine is provided. The internal combustion engine includes a plurality of cylinders. The internal combustion engine is configured such that when an intake valve of one cylinder on a compression stroke among the plurality of cylinders is open, an intake valve of each of the remainder of the plurality of cylinders is closed. The control device includes an electronic control unit configured to: (i) determine an open-closed state of the intake valve of each of the plurality of cylinders; and (ii) adjust an opening degree of a throttle valve to a first opening degree that is larger than a second opening degree corresponding to an idling operation, when the electronic control unit determines that the intake valve of any one of the plurality of cylinders is open at the time of startup of the internal combustion engine, to reduce compression torque and vibrations.
