Abstract
An internal combustion engine control apparatus includes means that detects an inlet temperature that is a temperature in a vicinity of an inlet of a purification catalyst disposed in an exhaust path and means that detects a turbine temperature that is a temperature in a vicinity of an exhaust turbine of a turbo-supercharger disposed in the exhaust path, and also includes means that controls a valve overlap that is a state in which an intake valve and an exhaust valve of the internal combustion engine are open simultaneously. When the inlet temperature is lower than an inlet high temperature reference value, and the turbine temperature is higher than a turbine high temperature reference value that is higher than the inlet high temperature reference value, the valve overlap amount is increased so as to be greater than a turbine high temperature time reference amount.
