PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine that can appropriately control an actual compression ratio in accordance with an operating state of the internal combustion engine including a compression ratio variable mechanism.SOLUTION: A control device for an internal combustion engine includes: sensing means for sensing occurrence of a knock; control means for controlling ignition timing; and a compression ratio variable mechanism for changing a compression ratio of the internal combustion engine. Until a knock occurs or until occurrence of the knock is stopped, the ignition timing is changed, and based on the variation of the ignition timing, the compression ratio variable mechanism is controlled, so as to change the compression ratio. Since the compression ratio is changed by the compression ratio variable mechanism in accordance with the knock occurrence state, operation at the optimal ignition timing and compression ratio corresponding to the condition during the state is enabled, so as to maximize an output. |
