Abstract
A control device for an internal combustion engine provided with an evaporated fuel processing device arranged to temporarily store an evaporated fuel generated in a fuel tank, to purge the evaporated fuel during drive of the engine, and to introduce the evaporated fuel to an intake system, and a variable compression ratio mechanism arranged to vary a mechanical compression ratio, the control device includes: a section configured to sense a state in which the evaporated fuel is accumulated in the evaporated fuel processing device, during a drive of the engine after a warming-up of the internal combustion engine is finished, the control device being arranged to purge the evaporated fuel by decreasing the mechanical compression ratio by the variable compression ratio mechanism when it is sensed that the evaporated fuel is accumulated.
