METHOD OF AND SMALLER VENTURI FOR FORMING FUEL MIXTURE FLOW IN CARBURETORS OF INTERNAL COMBUSTION ENGINES Russian patent published in 1999 - IPC

FIELD: automotive industry; internal combustion engines with vertical downwards CARBURETORS. SUBSTANCE: proposed method of fuel mixture formation includes delivery of air into venturi through channel, delivery of fuel-air emulsion through channel in venturi rib, swirling of mixture flow by twisting of flow around longitudinal axis by air streams through holes in lower part of venturi housing. Spiral vortex of flow is divided from by air stream through inclined channel in other rib of venturi. EFFECT: improved space and time homogeneity of mixture without decreasing flow velocity. 8 cl, 2 dwg
