Abstract
A fuel vapor generator in the form of a heat conductive member having an elongated U-shaped passageway formed through it. The member is mounted at the exterior of a carburetor venturi. A first open inlet end of the passageway extends through the venturi walls and receives atomized fuel from the main fuel nozzle and a portion of the incoming air. This fuel and air mixture is directed through the passageway where it is heated and the fuel is vaporized. The fuel and air are drawn from the passageway and returned into the venturi at a location downstream from the main nozzle. A series of mesh screens extending across the passageway and spaced along its length assist in atomizing the fuel and assuring efficient conduction of heat to the entire mixture of fuel and air within the passageway.
Claims11
A fuel vapor generator for an internal combustion engine including a carburetor that has a main nozzle with an outlet through which fuel is normally discharged into a venturi through which the fuel-air mixture is drawn into an intake manifold, the fuel vapor generator comprising:
- a hollow tubular member having interior walls which form a continuous passageway double back upon itself in an elongated configuration, the passageway terminating at open inlet and outlet ends located adjacent to one another;
- thermal insulating means surrounding the member at locations adjacent the inlet and outlet ends of the passageway adapted to fix the member to the exterior of a carburetor with the inlet end projecting into a portion of the venturi in receptive communication with the outlet of the main nozzle and with the outlet end projecting into the venturi downstream from the location of the inlet end to thereby direct the fuel and a portion of the air entering the carburetor through the passageway;
- means for heating the hollow tubular member to a temperature above the boiling point of the fuel.
The fuel vapor generator set out in claim 3, further comprising:
- a series of mesh screens each extending across the interior walls of the passageway and spaced apart from one another along the length of the passageway.
A fuel vapor generator for an internal combustion engine including a carburetor that has a main nozzle with an outlet through which fuel is normally discharged into a venturi through which the fuel-air mixture is drawn into an intake manifold, the fuel vapor generator comprising;
- a hollow tubular member having interior walls which form a continuous passageway doubled back upon itself in an elongated configuration, the passageway terminating at open inlet and outlet ends located adjacent to one another, said passageway having walls made of heat-conductive material;
- mounting means adapted to fix the member to the exterior of a carburetor with the passageway of the member leading to the interior of the carburetor through the walls of the carburetor venturi for locating the inlet end of the passageway adjacent to the outlet of the main nozzle of the carburetor and across a portion of the venturi and for locating the outlet end of the passageway at a location downstream from the outlet of the main nozzle of the carburetor to thereby direct the fuel and a portion of the air entering the carburetor through the passageway;
- and means for applying heat to the walls of the passageway intermediate its respective inlet and outlet ends.
In a carburetor for an internal combustion engine wherein the carburetor has a main nozzle with an outlet through which fuel is discharged and a venturi through which a fuel-air mixture is drawn into an intake manifold;
- the improvement comprising:
- a hollow member having an open elongated passageway formed therein leading between an inlet end and an outlet end, said passageway having walls made of heat-conductive material;
- mounting means for fixing the member to the exterior of the carburetor with the passageway of the member leading to the interior of the carburetor through the walls of the carburetor venturi for locating the inlet end of the passageway adjacent to the outlet of the main nozzle of the carburetor and for locating the outlet end of the passageway in the venturi of the carburetor at a location downstream from the outlet of the main nozzle of the carburetor;
- and means for applying heat to the walls of the passageway intermediate its respective inlet and outlet ends.
A method of vaporizing atomized fuel delivered from the main nozzle of a carburetor on an internal combustion engine;
- comprising the following steps:
- withdrawing the atomized fuel delivered from the main nozzle of the carburetor and a portion of the air entering the carburetor by directing the fuel and air into an elongated hollow member exterior to the carburetor and thermally insulated therefrom;
- directing the fuel and air mixture in said member back into the venturi of the carburetor downstream from the main nozzle;
- and applying heat to the fuel and air mixture while it is exterior of the carburetor.
