  • Control Of The Air-Fuel Ratio Of Carburetors (AREA)

Abstract

PURPOSE: To prevent excessive enrichment of fuel by putting the motion off of a high output power system of a carburetor at high temperatures of an engine.
CONSTITUTION: A fuel passage 23 connects a carburetor float chamber 25 to a main nozzle which is not shown in the drawing. There are formed a power jet 21 opening to the fuel passage 23, power valve 19 overhanging the jet and power piston 16 connecting to a rod 18. A negative pressure room 17 on the piston 16 is connected to an intake pipe 3 by negative pressure passages 14, 29 and an orifice 5. In high load operation, the intake pipe reduces in negative pressure to open the power valve 19, which increases the amount of fuel supplied. A bimetal case 26 makes free communication of the space 7 of the negative pressure passage 29 with atmosphere. At high temperatures of an engine, the bimetal valve 10 is opened to raise the pressure in the negative pressure passage 14 so that the power system may become inoperative.
