CARBURETOR FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: internal combustion engines. SUBSTANCE: CARBURETOR has mixing chamber 1 with throttle valve 2, atomizer 3 of main metering system made in form of hollow truncated cone connected with emulsion well 5 of main metering system by means of passage 4; emulsion well 5 is brought in communication with float chamber 6 through passage 7; CARBURETOR is also provided with main air jet 9 with adjusting screw 10. Idling system and adapter system are additionally provided with atomizers 11 and 12 made in form of orifices in which jets 13 and 14 fitted with adjusting screws 15 and 16 are inserted. At idling, fuel emulsion is fed via passage to atomizer 11 where it is sprayed under action of vacuum and then it is mixed with main flow of air. As throttle valve is opening, first atomizer 12 of adapter system and then atomizer 3 of main metering system are placed in operation. During operation of engine at maximum modes, microswitch 20 disconnects electromagnetic valve 17; as a result, its core 18 shuts off air passage 19 of main air jet 9; thus enriching the fuel mixture. EFFECT: enhanced efficiency. 1 dwg
