Abstract: In the art of motor fuel carburetion where conventional carburetors are employed to mix and prepare the fuel/air mixture for introduction into the combustion chamber of internal combustion engines, and particularly where gasoline is used as fuel, the liquid fuel is sucked, or aspirated out of the provided discharge opening by the current of intake air as it flows past this opening, thereby presumably mixing and preparing the fuel/air charge.In this invention the method of mixing liquid fuel with air employs a liquid fuel delivery spray valve which is so located as to spray liquid fuel upon an electrically heated metal plate which instantly converts the fuel from its liquid state into vapor form; a water delivery spray valve which is so located in similar fashion as the fuel delivery valve described above, to moderate the explosive violence of high octane fuel in the combustion chamber of internal combustion engines; and an electrically heated porous screen to atomize the fuel/air/steam mixture charge.
