Abstract:
A control apparatus of an internal combustion engine provided with a variable valve operating apparatus which variably changes a valve operating characteristic of at least one of an intake valve and an exhaust valve, comprising:an intake pipe pressure detector that detects an intake pipe pressure of said internal combustion engine; an operating condition detector that detects an operating condition of said internal combustion engine; a computing unit that computes a reference intake pipe pressure and a reference fresh air ratio corresponding to a reference operating condition of said variable valve operating apparatus based on the detection value of the operating condition of said internal combustion engine, computes a fresh air ratio correction amount corresponding to an operating condition of said variable valve operating apparatus based on the detection value of said intake pipe pressure and said reference intake pipe pressure, corrects said reference fresh air ratio based on said fresh air ratio correction amount to compute a final fresh air ratio, and computes an operating amount of a control object in said internal combustion engine based on said final fresh air ratio; and an operating device that operates said control object in said internal combustion engine by said operating amount.
