Abstract
A control device of an internal combustion engine comprises a heater control part configured to set a target temperature of the electrochemical cell and control the heater so that a temperature of the electrochemical cell becomes the target temperature. The heater control part sets the target temperature to a first temperature when water injection by the water injection device is not being demanded after a predetermined time elapses from startup of the internal combustion engine, and sets the target temperature to a second temperature when an operating state of the internal combustion engine is in a water outflow state where water injected by the water injection device reaches the exhaust passage without going through combustion of air-fuel mixture in the combustion chamber. The second temperature is higher than the first temperature.
