置。In a water injection device for an internal combustion engine, an injection nozzle is provided at the engine intake port and water is injected into the combustion chamber through the intake valve toward the exhaust valve. A control valve that opens when the engine output is high is provided in a water supply passage that guides discharged water to the injection nozzle, and a delay means that delays the operation timing of the pump by a predetermined period from the opening of the intake valve. water injection device for internal combustion engines.
