ABSTRACT:
Unequal fuel concentrations in air-fuel mixtures delivered by a downdraft carburetor to branched intake pipes leading to engine cylinders has been traced to asymmetrical fuel delivery into the venturi passage in the carburetor. To equalize the fuel concentrations carried in the branched pipes, an inclined wall is provided in the distribution chamber that receives the air-fuel mixture from the carburetor. The inclination of the wall directs a greater quantity of air-fuel mixture into the branched pipe which would otherwise receive a leaner mixture because of the asymmetrical distribution of fuel from the venturi passage.
