Air distribution apparatus for use with an internal combustion engine

摘要

An air-distribution apparatus for use with an internal combustion engine, wherein end portions of a plurality of branched air-intake tubes are respectively connected to air-intake holes of respective cylinders of a multiple-cylinder engine. A multiple-barrel carburetor is connected above a mounting assembly unit installed substantially at the center of the plurality of branched air-intake tubes so that each barrel communicates with the intake tubes through a respective air-intake port formed in the top wall of the mounting unit. A primary barrel of the carburetor is disposed in alignment with a transverse centerline of the mounting unit, and a secondary barrel of the carburetor is disposed in a position wherein it is displaced sidewardly from the centerline in the direction of the fuel nozzle tubes which connect to both barrels of the carburetor so as to permit more proper balancing of the air and fuel ratio as supplied to each cylinder.
