SWIRLED JET AIR-FUEL MIXER Russian patent published in 2011 - IPC F02M23/00 F02M29/00 B01F13/02 

FIELD: engines and pumps.

SUBSTANCE: proposed mixer consists of inlet manifold with inner hole, fuel injector, vortex chamber combined with inlet manifold. It features inner surface representing modernised Laval nozzle with two truncated cones with their minor holes facing each other and cylindrical groove arranged there between. Tangential inclined holes are made in said groove. Outer surface forms with inner surface of inlet manifold semi-open cylindrical mixing chamber. Inlet manifold casing has additional holes in vortex chamber zone. Nozzle with inner surface formed by tapered or conoid nozzle and diffuser (diffuser nozzle) are arranged at modernized Laval nozzle inlet. Larger diameter of said tapered or conoid nozzle equals inlet manifold inner hole diameter. Nozzle outer surface and inlet manifold inner surface form additional annular mixing chamber. Peripheral holes are made at nozzle inlet parallel with mixer axis. Modernised Laval nozzle outlet is provided with additional section with cylindrical inner cross section.

EFFECT: higher efficiency of mixing, complete combustion.
