Abstract
A control apparatus for an internal combustion engine having two cylinder groups and two variable valve control mechanisms provided to the respective cylinder groups, includes a detecting section that detects an incylinder pressure of each cylinder, a comparing section that makes a comparison between the two cylinder groups with respect to a combustion stability and a control section that varies valve lift characteristics of intake valves of one cylinder group which is larger in the average incylinder pressure than the other cylinder group in accordance with a result of comparison by the comparing section so as to make intake air quantities for the respective cylinder groups be equal to each other.
