FIELD: carburetors with porous inserts at joint control of fuel and air delivery. SUBSTANCE: carburetor includes housing with straight-way passage where atomizer and throttle valve are mounted. In addition to main emulsion chamber, carburetor includes additional preliminary emulsion chambers of main metering system and idling system, respectively. Atomizer is provided with porous side walls. Fuel is preliminarily mixed with air in prechambers and then it is practically fully evaporated in emulsion chamber due to porous insert and is finally evaporated during escape through side walls of atomizer. Three-stage evaporation of fuel and mixing of it with air ensures reliable and efficient operation in all modes of operation under any climatic conditions. EFFECT: enhanced and reliability of carburetor. 1 dwg
