    摘要: Apparatus for homogeneously intermixing flows of fuel and air to an internal combustion engine comprises a mixing chamber having a venturi portion across which is disposed an arcuate nozzle-matrix of converging nozzle cells which focus subflows toward pre-selected downstream crossflow mixing zones. A mainstream flow of air is introduced into the chamber upstream of the nozzle-matrix and one or more mainstream flows of fuel are introduced into the chamber upstream of the nozzle-matrix and/or into the crossflow mixing zones. The nozzle-matrix is adapted to accept at least portions of the main upstream flows to generate several optimum velocity subflows therefrom to enhance fuel and dispersion, atomization, and vaporization into the air. A transversely movable cylindrical gate, installed through a wall of the chamber, is provided for selectively restricting subflows through at least some of the nozzle cells to thereby vary the effective combined cross-sectional area of the nozzle-matrix and maintain pre-selected velocity subflows through the unrestricted nozzle cells over wide ranges of engine fuel-air mixture demands. The substantially homogeneous fuel-air mixture is discharged from a lower region of the chamber, downstream of the nozzle-matrix, into an engine intake manifold. Several variations are illustrated and described. Corresponding methods of homogeneously intermixing fuel and air are provided.

    摘要: A sonic flow, plug type carburetor has an annular fuel induction slot in the periphery of the plug connected to an air/fuel mixture supply in the plug, and fuel distribution means in the plug in the form of an air turbine located adjacent the slot and in a position to receive liquid fuel from the air/fuel mixture to centrifuge the fuel globules outwardly and thinly spread the fuel as a film uniformally around the annulus of the induction slot for a uniform entry into the air stream.

    摘要: Discharge velocity of the air-fuel mixture being supplied through a variable venturi flow passage device to an internal combustion engine is optimized by controllably varying or maintaining area ratio between the throat and exit planes of the device. Opposite jaw faces of the device define the flow passage that is gradually opened and closed in correlation to demand imposed on the engine between idle and full throttle operation. Opening and closing of the jaws are effected by concomitant pivoting of each jaw about separate axes respectively displaced longitudinally in the direction of flow therebetween. By pivoting one jaw on an axis contiguous to or in the vicinity of the throat plane and the other jaw on an axis contiguous to or in the vicinity of the exit plane, any predetermined area ratio or change in area ratio can be preset throughout the operating range of the device.
