  • Patent number: 4375801
    Abstract: A device for mixing and atomizing the fuel-air flow which is positioned between the carburetor and the intake of an internal combustion engine. The device comprises a swirl chamber which creates turbulence in the fuel-air flow by turning a portion of the flow upstream into the downward flow going to the engine intake and has a trough which collects liquid fuel droplets which have landed on the swirl chamber wall. The liquid fuel collected in the trough is vaporized by the heat of the engine and then re-enters the fuel-air flow.
