CARBURETOR OF INTERNAL COMBUSTION ENGINE Russian patent published in 2006 - IPC F02M19/03 F02M29/00 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to systems for preparing fuel-air mixture in internal combustion engines. Proposed carburetor contains housing with through channels and mixing chambers, smaller and larger ventures arranged in corresponding through channel, emulsion tubes of main metering systems and main atomizer. Emulsion tubes are provided with one row of holes diameter of which is smaller than diameter of hole of air jet of main metering system. Holes on each emulsion tube are arranged one over the other, being pointed to side of emulsion channel of main atomizer. Smaller venture is made in form of hollow cylinder provided with narrowing upper part with insert forming, after narrowing upper part of smaller venture, step narrowing and terminating directly under main atomizer. Length of main atomizer is less than half of diameter of smaller venture, thanks to which hole of atomizer is displaced from axis of smaller venture.

EFFECT: provision of quality fuel-air mixture which guarantees its complete combustion in engine with reduction of discharge of harmful substances and increase of engine efficiency.
