Claims

[Scope of Claim for Utility Model Registration] A horizontal carburetor is installed with the carburetor installation center of the intake manifold offset from the center of the engine body, and the intake manifold curved in a horizontal U-shape is connected below the carburetor. In the multi-cylinder engine, an insulator is interposed at the joint between the horizontal carburetor and the intake manifold, and the upper side of the opening of the insulator avoids the side where the slow port of the horizontal carburetor opens, An intake air distribution device for a multi-cylinder engine, characterized in that a rectifier piece is provided protruding from an opening on the opposite side of the opening of the insulator between the center of the horizontal carburetor and the center of the engine main body.
