ABSTRACT:
A fuel and air mixture induction system is provided for an internal combustion engine and includes a conventional air and fuel mixing carburetor for starting the engine when the latter is cold. However, when operating temperatures of the engine are reached the air and fuel induction system is operative to more thoroughly vaporize liquid fuel by pressurizing and heating not only the induction air but also the fuel and spraying the heated fuel into the heated induction air in a manner such that substantially complete fuel atomization and vaporization occurs. This pressurized fully vaporized fuel and air charge is thereafter discharged in a downstream direction into the air and fuel passage of the carburetor closely upstream from the venturi area thereof. The supply of liquid fuel to the carburetor is maintained, but the fuel flow from the carburetor float chamber is automatically reduced when the supply of vaporized fuel and air is furnished because the air and vaporized fuel is supplied to the carburetor under a low pressure thus effectively reducing the reduced venturi area pressure normally associated with a carburetor and the flow of fuel from the carburetor float chamber to the venturi area. In addition, normal opening of the throttle valves is decreased when the supply of heated air and fully vaporized fuel is supplied to the carburetor. Therefore, a smaller amount of air and fuel vapors pass through the carburetor to further reduce the vacuum at the venturi passage and thus the flow of fuel from the carburetor flow chamber into the venturi passage.
