ABSTRACT:
A multi-layered screen with layers closely spaced positioned for use in carburetor equipped internal combustion motors in the manifold openings beneath the carburetor in the path of intake air flow with, under a one-barrel carburetor one multi-layered screen being used, with a two-barrel carburetor one or two multi-layered screen units are used depending on whether one barrel is a kick in barrel for acceleration, and in a four-barrel carburetor two are used for the normal run barrels with none in the two kick in barrels that come into use for heavy acceleration. The multi-layered screen units in concentric cylinder form, concentric truncated conical form or spiral wound form, are positioned so that fuel laden air from the carburetor passes through screening of the multi-layered screen units with the mesh and wire size of the screening coupled with the shape and close adjacency of the multi-layers of each screen unit such as to optimize vaporization atomizing of fuel in the fuel air mixture being fed to the motor.
