Water supply control apparatus for in-cylinder injection type internal combustion engine

摘要

A water supply control apparatus is applied to an in-cylinder injection type internal combustion engine (1) which injects fuel from a central area (2a) in a cylinder (2). The water supply control apparatus comprises a condensed water supply mechanism (22) where a state of supplying condensed water (CW) into the cylinder (2) is changeable between a first supply state that the condensed water (CW) is supplied to a whole inside of the cylinder (2) and a second supply state that the condensed water (CW) is limitedly supplied to the central area (2a) of the cylinder (2). In the second supply state, the supply amount of condensed water supplied into the cylinder (2) in the second supply state is less than the supply amount of condensed water supplied into the cylinder (2) in the first supply state.
