Abstract
A control device for an internal combustion engine includes an air-fuel ratio controller to execute a stoichiometric operation in which an air-fuel ratio of an air-fuel mixture in a combustion chamber of the internal combustion engine is set to a stoichiometric air-fuel ratio and a lean operation in which the air-fuel ratio is set to an air-fuel ratio leaner than the stoichiometric air-fuel ratio. A ignition timing controller is to calculate at least one ignition timing control parameter based on a laminar combustion velocity and to control an ignition plug provided in the combustion chamber to ignite based on the at least one ignition timing control parameter in a transitional state between the stoichiometric operation and the lean operation.
