Claim:
1. A control apparatus of an internal combustion engine, the internal combustion engine including a first variable valve mechanism configured to change a valve-open period of an intake valve, and a second variable valve mechanism that changes a valve-open period of an exhaust valve, the control apparatus comprising: an electronic control unit configured to control driving of the first variable valve mechanism and the second variable valve mechanism, the electronic control unit being configured to execute a process to increase the valve-open period of the intake valve and reduce the valve-open period of the exhaust valve in order to maintain or decrease a valve overlap amount of the intake valve and the exhaust valve and to inhibit an increase in the valve overlap amount of the intake valve and the exhaust valve, and the electronic control unit being configured to execute the process when idling at which a temperature of the internal combustion engine is equal to or higher than a reference value.
