Abstract:
A water supply control device is applied to an in-cylinder injection internal combustion engine (1) for injecting fuel from a middle part (2a) inside a cylinder (2). The water supply control device is provided with a condensed water supply mechanism (22) that can change the state of supply of condensed water (CW) into the cylinder (2) between a first supply state of supplying condensed water (CW) into the entire interior of the cylinder (2), and a second supply state of supplying condensed water (CW) to a limited extent to the middle part (2a) inside the cylinder (2). The amount of water supplied into the cylinder (2) during the second supply state is less than the amount of water supplied into the cylinder (2) during the first supply state.
