Control apparatus of internal combustion engine

The invention relates to a control apparatus (115) of a cylinder injection of fuel type internal combustion engine (107) executing a dilute combustion, which can satisfy a requirement of rapidly changing an engine torque while restricting a deterioration of a driving property and an exhaust gas as much as possible. In a control apparatus (115) of a multicylinder engine executing a dilute combustion, in the case that a requirement of reducing and changing an engine torque of the internal combustion engine is applied, the control apparatus (115) executes a fuel cut of a predetermined number of cylinders, and controls so that a torque of operating cylinders except the cylinders executing the fuel cut becomes the required engine torque (304).
