Claims

[Scope of utility model registration request]

In an internal combustion engine equipped with a water injection device that injects pressurized water from a water tank directly into the combustion chamber of the engine via a pump, the nozzle passage of the injection nozzle is formed inside the intake valve and also in the cylinder head. A valve means is provided to communicate the pressurized water supply passage with the nozzle passage provided in the valve stem only when the intake valve is lifted. 1. A water injection device for an internal combustion engine, characterized in that the opening is oriented toward the upper wall surface of a combustion chamber so as to hit the upper wall surface of the combustion chamber.
