Abstract
Provided is a control device for an internal combustion engine, which can control an injection amount of water injected into each cylinder of the internal combustion engine to a minimum injection amount that allows knock to be suppressed for each cylinder. Therefore, in a control devicethat controls water supply valves(water supply devices) that supply water into each of combustion chambers of a plurality of cylinders R (cylinders Rto Rin the embodiment) of an internal combustion engine, the control deviceincludes a water supply amount calculation unitthat calculates a supply amount of water supplied to each of the combustion chambers of the plurality of cylinders Rto Rfor each cylinder, and a water supply control unitthat controls the water supply valvesbased on the supply amount of water calculated by the water supply amount calculation unitfor each cylinder.
