FIELD: mechanical engineering; internal combustion engines with carburetor furnished with fuel-air ratio control means; microengines. SUBSTANCE: to provide reliable stable operation of carburetor at any modes fuel metering is provided inside carburetor body out of the limits of air channel. At throttling, cylindrical throttle valve which has inner ring groove moves along longitudinal axis and overlaps with its groove a V-shaped channel located along axis on fuel atomizer. Additional fuel chamber is used to provide good pickup. Fuel from this chamber is forced by throttle valve into air channel. At sharp throttling, fuel is injected into air channel of carburetor. EFFECT: enhanced reliability and stable operation of carburetor. |
