Fuel-air mixture feed device of the multiple cylinder and multiple carburetor type for an internal combustion engine

摘要

A fuel-air mixture feed device for use with a multiple cylinder internal combustion engine having at least one carburetor for high loads, and at least one carburetor for high and low loads, comprising main conduits connecting the cylinders to the carburetors and at least one branch conduit connecting the main conduits to each other. By this arrangement, the carburetor for high loads is rendered inoperative at low loads and the carburetor for high and low loads is operated to feed fuel-air mixtures to the cylinders, while all the carburetors are operated at high loads so that maximum power can be obtained at all time.
