Abstract:
An ECU equipped with a state determination unit for determining a change in the state of an engine, and an intake valve phase change unit for outputting an instruction in order to change the phase of the intake valve on the basis of the change in the state of the engine, wherein the intake valve phase change unit distances the closing timing of the intake valve from the bottom dead center when the engine is stopped in a manner such that the catalyst temperature when starting the engine of a three-way catalyst provided to an exhaust pipe of the engine is no less than a prescribed value (catalyst temperature prescribed value) which does not decrease the purification efficiency for exhaust discharged from the exhaust pipe.
