Abstract
A control apparatus includes a detection unit that detects a stop request to an engine, a throttle closing control unit that, when the stop request is detected, adjusts an opening amount of a throttle valve to an engine-stop throttle valve opening amount smaller than a current opening amount an engine stop detection unit that detects a stop of the engine, an engine-stop exhaust valve control unit that adjusts an opening/closing characteristic of an exhaust valve of a cylinder that will be placed initially in an intake stroke when the engine is restarted so that, when the opening amount of the throttle valve is adjusted to the engine-stop throttle valve opening amount and a stop of the engine is detected, the exhaust valve has an engine-stop exhaust valve opening/closing characteristic by which a closing timing of the exhaust valve is more delayed than a current closing timing of the exhaust valve.
