ABSTRACT:
A low pressure fuel tube delivers fuel to a fuel injector disposed in the central position of the carburetor dome where it is conducted along a plurality of radially extending passages to the periphery of the injector. A high pressure air supply is provided directly to the peripheral fuel flow, in a substantially radial direction, by a disc surrounding the nozzle and having a plurality of radially extending passageways formed therein. A portion of the fuel is blasted directly onto a surrounding venturi surface where it is swirled in a given direction and then exits the downstream end of the venturi where it interacts with a counterrotating pattern of air from the secondary swirler flow to be atomized into a mist. Another portion of the air-blasted fuel from the venturi flows in the axial direction to also enter the combustor as a finely atomized fuel/air mixture.
