Abstract
The disclosed internal combustion engine has an electric water pump and a water temperature sensor that detects coolant water temperature. An electronic control device stops the driving of the water pump when the coolant water temperature is lower than a baseline temperature. Meanwhile, the electronic control device drives the water pump in accordance with the coolant water temperature when the coolant water temperature is higher than the baseline temperature. When the driving of the water pump is stopped, the internal combustion engine forbids at least one engine control until the water pump is driven.
