ABSTRACT:
A flanged plate for insertion between the carburetor and manifold bores for an internal combustion engine to intercept the fuel-air mixture immediately after it leaves the carburetor around the throttle valve therefor. The plate comprises a plurality of flanged areas constructed and defined to intercept the fuel and air mixture while minimizing the restriction of the flow. The flanged areas are defined over 180 degrees of the carburetor bore to generate a multiplicity of small vortices that interfere with and reduce the large vortex that is generally produced immediately below the carburetor's throttle valve. The interaction of the vortices causes a reduction in back pressure, improved mixing of the fuel and air and increased volume of flow of the fuel and air mixture into the engine leading to more complete combustion and increased miles per gallon of fuel with a cleaner exhaust stream.
