Abstract
A control device of an engine includes an adjustment mechanism and a controller. The adjustment mechanism is configured to adjust an intake air amount. The controller is configured to save a first learning value in a volatile storage medium, the first learning value being obtained by learning an operation amount of the adjustment mechanism when the engine is idle. The controller is configured to control the adjustment mechanism according to the first learning value. The controller is configured to save a second learning value in a non-volatile storage medium, the second learning value being equal to the first learning value. The controller is configured to correct the first learning value using the second learning value after the first learning value is cleared.
