Abstract
A control device for an internal combustion engine is provided. The internal combustion engine is configured to perform switching between an all-cylinder operation and a partial cylinder operation. The internal combustion engine includes a temperature regulator. The temperature regulator is configured to separately regulate the temperature of an operating cylinder and the temperature of a paused cylinder. The operating cylinder is a cylinder that operates during the partial cylinder operation. The paused cylinder is a cylinder that is paused during the partial cylinder operation. The control device includes an electronic control unit. The electronic control unit is configured to (i) calculate a temperature difference between the operating cylinder and the paused cylinder during the partial cylinder operation, and (ii) control the temperature regulator such that the temperature difference becomes equal to or smaller than a predetermined threshold.
