PROBLEM TO BE SOLVED: To provide a control device for controlling a cylinder-direct-injection internal combustion engine provided with a cylinder deactivation mechanism, capable of preventing damage to the internal combustion engine while preventing the degradation of exhaust characteristics.SOLUTION: A device for controlling a cylinder-direct-injection internal combustion engine provided with a cylinder deactivation mechanism switched over between a first state of activating all of a plurality of cylinders and a second state of fixing an intake valve and an exhaust valve of a cylinder to be deactivated to closed states in response to a switching indication, implements fuel cut when the cylinder deactivation mechanism is made into the second state, and issues a request to cancel the fuel cut when the cylinder deactivation mechanism is switched from the second state to the first state (S520). Furthermore, the device comprises means (S510) for calculating a possibility of the occurrence of an abnormality that the cylinder deactivation mechanism is kept in the second state; and means (S560, S580) for issuing a request to implement a process for preventing burning in the cylinder to be deactivated when the cylinder deactivation mechanism is in the second state and the abovementioned possibility is equal to or higher than a predetermined value.SELECTED DRAWING: Figure 13 |
