Abstract:
1. A control apparatus for an internal combustion engine, the apparatus comprising: a variable valve operating apparatus which is capable of changing an operational state of at least one of an intake valve and an exhaust valve between a valve operating state and a valve closed/stopped state, has an electrically-driven actuator, and is configured so that the operational state of the at least one of the valves becomes the valve closed/stopped state in response to a valve stop command to the actuator and so that the operational state of the at least one of the valves is returned to the valve operating state when a camshaft rotates by a predetermined angle after a valve return command to the actuator is issued; valve stop command means for issuing the valve stop command to the actuator so that the operational state of the at least one of the valves becomes the valve closed/stopped state when fuel supply to the internal combustion engine is stopped in response to an establishment of a predetermined stop condition of the internal combustion engine; valve return command means for issuing the valve return command to the actuator so that the operational state of the at least one of the valves is returned to the valve operating state during a predetermined time period immediately before a completion of a stopping operation of the internal combustion engine or after a completion of the stopping operation; and camshaft drive means for rotationally driving the camshaft by the predetermined angle required to return the operational state of the at least one of the valves to the valve operating state at or after a time point when the valve return command is issued by the valve return command means.
