可変ベンチユリ気化器の燃料増量装置。 The negative pressure in the bench lily is kept constant by the reciprocating movement of the suction piston upon sensing the negative pressure in the suction piston, and the metering needle and metering jet are adjusted by the reciprocating movement of the metering needle corresponding to the reciprocating movement of the suction piston. In a variable vent valve carburetor that changes the amount of fuel supplied to the intake passage by changing the annular area between the two, the metering jet is bypassed and fuel from the float chamber of the carburetor is supplied to the intake passage. A fuel increasing solenoid valve is provided with a bypass passage for supplying fuel, and supplies an arbitrary amount of increased fuel to an intake passage, which is determined by duty ratio control of an electromagnetic solenoid based on outputs from various sensors corresponding to engine operating conditions. A fuel increasing device for a variable bench lily carburetor, characterized in that it is provided with:
