ABSTRACT:
A dished screen placed in engine intake manifold openings beneath a carburetor in the path of intake air flow with, under a one-barrel carburetor one recess dished screen being used, and with a two-barrel carburetor two recess dished screens being used. The screen units are positioned so that fuel laden air from the carburetor passes through screening of the screen units with the mesh and wire size of the screening coupled with depressed dished shape of the screen units such as to optimize vaporization atomizing of fuel in the fuel air mixture being fed to the engine. The proper shape and screening size of the dished screen units is an excellent trade-off of intake air/fuel mixture flow obstruction for more efficient fuel utilization resulting in more power and significantly improved mileage and decreased undesired emissions.
