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.

A water injection system for a combustion engine, comprising reservoir means for containing a supply of water, pump means for pumping said water from said reservoir to said engine, means responsive to indicia of engine load for at times permitting water pumped by said pump means to be discharged to said engine, said means responsive to indicia of engine load being effective to permit a plurality of generally constant rates of flow of said water to be discharged to said engine in a manner whereby there is no cessation of the flow of said water as between succeeding ones of said plurality of generally constant rates of flow of said water, and water flow circuit means communicating generally between said pump means and said engine, wherein said water flow circuit means comprises parallel flow paths, wherein said means responsive to indicia of engine load comprises a valve member, and wherein said valve member controls the flow of said water through at least one of said parallel flow paths.
