Abstract
An internal combustion engine is shown having an intake manifold and carburetor to which water is injected or sprayed by an electrically powered pump receiving water from a reservoir; switches responsive to engine temperature, engine oil pressure and engine intake manifold vacuum serve to determine whether the circuitry for energizing the pump will be opened or closed; a valve member responsive to the intake manifold vacuum serves to permit a greater rate of flow of the water to the engine upon the manifold vacuum decreasing to a predetermined magnitude.
