The invention consists of a plate-like member disposed between the carburetor and the intake manifold of an internal combustion engine and has a bore therethrough in register with the throat of the carburetor and the intake of the manifold. The plate-like member has an unobstructed annular air inlet into its bore and a passage across the bore having a jet nozzle axially of the bore directed at the intake of the manifold, the air stream from the annular inlet diverts the fuel and air mixture from the carburetor to be confined centrally of the bore and the jet stream of air from the jet nozzle creates a virtual venturi to cause the incoming fuel and air mixture to flow directly through the core of the intake of the manifold without engaging the side walls thereof, the impact of the intersection of the air stream from the annular inlet and the jet stream together with the fuel and air mixture from the carburetor causes a cyclonic action which further atomizes the fuel and air mixture and increases its homogenity upon entering the intake of the manifold for a more complete combustion.
