Double carburetor |
摘要 |
A double carburetor including a primary suction conduit and a secondary suction conduit located in a suction passage of an internal combustion engine equipped with a turbosupercharger for supplying supercharged air to a combustion chamber by means of a compressor driven by a turbine rotated by the energy of exhausts has an air-fuel ratio correcting control valve for a primary main fuel system of the primary suction conduit and another air-fuel ratio correcting control valve for a secondary main fuel system of the secondary suction conduit. The carburetor also has a drive unit which is operative, when the turbosupercharger is put into action, to actuate the air-fuel ratio correcting control valves for the primary and secondary main fuel systems to correct the air-fuel ratio of fuel-air mixtures supplied to the engine by increasing fuel flow or decreasing air flow therethrough.
