  • Patent number: 8051846
    Abstract: Through holes formed on an atomization pipe can prevent fuel adhering on inner walls of the through holes from escaping. In addition, when fuel adhering on an inner circumferential surface of the atomization pipe flows toward a downstream side, the fuel enters the through holes. Thus, the fuel can be confined therein. Furthermore, an absorbing member can absorb the fuel that has adhered to a downstream inner wall of the atomization pipe and flows toward the downstream side. Moreover, a periphery of the intake passage hole of a gasket protrudes from the inner wall, so that flow of the fuel that the absorbing member fails to absorb toward the downstream side can be blocked. Accordingly, a rapid increase in the amount of fuel flowing into the engine body can be reliably prevented. Therefore, fluctuation in the number of revolutions of the engine can be sufficiently restrained.

  • Patent number: 4796596
    Abstract: A fuel saving device comprising a chamber formed within a housing adapted to be mounted between the carburetor and the intake manifold of an internal combustion engine, the chamber having an inlet end opening which registers with the discharge passage of the carburetor and receives a fuel-air mixture formed in the carburetor, and an outlet end opening which connects to the intake manifold. Micro-porous filter plates are mounted in the chamber transversely to the path of flow of the fuel-air mixture, are spaced from each other in the direction of flow, and a bypass passage is associated with some of the filter plates. Increased vaporization of the fuel results from the flow of the fuel-air mixture around and through the filter plates with the result that the fuel quantity can be reduced, fuel economy improved, and exhaust emissions decreased.

  • Patent number: 4715346
    Abstract: A carburetor for an internal combustion engine has a long multi-stage mixing path for the air and fuel to completely mix, the path being formed by three mixing chambers arranged vertically in tandem. Each chamber has a spirally extending pathway. The air and liquid fuel is sprayed into an outer portion of the top chamber and flows toward the central portion to enter the next adjacent chamber at the center, and continues to flow in the pathway in the second chamber spirally outwardly to enter the pathway in the third chamber at an outer portion from which it flows toward the center of the third chamber out the carburetor into the intake manifold of the engine. The first chamber has a cyclonic funnel in the central portion thereof so that the less volatile heavy unvaporized liquid fuel particles flowing in the first chamber are collected in a reservoir disposed at the bottom of the funnel.

  • Patent number: 4702220
    Abstract: A tubular body projects through the normal inlet opening in the inlet manifold of a conventional internal combustion engine. The quantity of fuel mixture flowing through the bore in the body is controlled by a throttle valve which is reciprocally movable relative the discharge end of the body which resides within the manifold. Biasing means normally retracts the valve to an engine idle position. The valve is extended in response to engine demand. Droplets of liquid within the fuel mixture are atomized in response to an annular deflector which directs the mixture from the sidewall of the bore to be impinged upon the planar surface of the valve. A stationary screen encompassing the valve further atomizes the mixture. Baffels are provided to direct the fuel charge toward the combustion chambers.

  • Patent number: 4667648
    Abstract: An assembly being interposed between a carburetor and an intake manifold comprises three spacer plates and at least two screens for vaporizing the highest concentration of fuel and for passing unobstructed the highest concentration of air traveling therethrough. The top and bottom screens are separate and parallel and extend traversely across and are substantially perpendicular to the primary passageway formed by the aligned centrally located primary passageway openings in each spacer plate. The top screen covers approximately one-half the cross-sectional area of the primary passageway opening. The bottom screen covers approximately one-third the cross-sectional area of the primary passageway opening, and both screens are situated and positioned directly below the back side of the carburetor's throttle valve.

  • Patent number: 4628890
    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.

  • Patent number: 4611567
    Abstract: A vaporizer unit has an enclosing casing including a plurality of tubes therein, defining a fuel passage therethrough, including the tubes. The tubes have coiled wire screen therein. An auxiliary carburetor is positioned at the inlet end of the fuel passage, and an outlet passage leads to the main carburetor of the automobile. The casing also defines an exhaust passage therethrough, transversely of the fuel passage, providing heat transfer between the exhaust gases and the tubes. The temperature of the resulting vaporized fuel is sensed for varying the flow of the exhaust gases and thereby controlling the temperature of the vaporized fuel, which is maintained at 250.degree. F. to 260.degree. F. An electric crystal is used for breaking down the heavy ends of the fuel. The rate of flow of air to the main carburetor is varied for correspondingly varying the rate of intake of vaporized fuel from the vaporizer unit.
