Abstract
A control apparatus is applied to an internal combustion engine equipped with a plurality of cylinders, a variable valve actuation system capable of switching the operation mode of intake and exhaust valve between an inactive mode and an active mode on a cylinder-by-cylinder basis, and a fuel injection valve capable of supplying fuel to each cylinder. When the engine speed is equal to or lower than a first engine speed, the control apparatus performs cylinder deactivation in the internal combustion engine by skip firing control. When the engine speed is higher than the first engine speed, the control apparatus performs cylinder deactivation in the internal combustion engine by fixed deactivated cylinder control.
