Fuel atomizer

Abstract

A plate having a plurality of apertures through which a fuel-air mixture travels is positioned between a fuel injector, such as a carburetor, and an intake manifold of an internal combustion engine. The apertures taper outwardly toward the intake manifold from a restricted orifice area adjacent the fuel injector. The taper of the apertures allows the fuel-air mixture to expand and provides better atomization of the fuel. The size and shape of the apertures is such as to cause ultrasonic sound and reverberation which is a phenomena that helps break up the droplets of fuel into minute droplets. The preferred embodiment includes a ratio of the restricted aperture area in the plate to the total displacement of the engine from 0.006 to 0.012, with the optimum ratio being approximately 0.007. The inside surface of the tapered apertures includes longitudinal flutes extending from the upper to the lower surface of the plate. The longitudinal flutes allow better attachment of the air molecules to the surface of the apertures and prevents swirling or rotation of the fuel-air mixture. The atomizer provides highly improved fuel economy and a lowering of noxious emissions. A mask element is provided to limit the air-fuel mixture to a predetermined pattern, and openings around the pattern limit heat transfer to the air-fuel mixture.
