Abstract
An engine control device includes: an electronically controlled throttle which controls a flow rate of air-fuel mixture flowing into a cylinder of an engine by controlling a throttle opening angle electronically; an ignition device which ignites an air-fuel mixture existing in the cylinder; and an engine control unit which executes an ignition timing/throttle opening angle changing process of controlling the ignition device and the electronically controlled throttle while an operation of a body to be driven by the engine is in a steady state so as to advance a timing of ignition of an air-fuel mixture existing in the cylinder and to reduce the throttle opening angle while torque of the engine is kept constant.
