Abstract
Abstract An apparatus and process for atomizing a fuel-air mixture in an internal combustion engine by causing the fuel-air mixture to be driven in a funnel-type flow pattern in a passageway located between the engine's carburetor and intake manifold. The passageway includes a foraminous member disposed therein having an aperture and a grommet-rim therefore which comprises an aerodynamic surface in the path of the fuel-air mixture. The aerodynamic surface causes the fuel-air mixture to be driven in a circular path adjacent the outer wall of the passageway. The swirling fuel-air mixture is then drawn through the foraminous member where it is further atomized and conveyed to the intake manifold.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
In an apparatus for atomizing a fuel-air mixture in an internal combustion engine having a a carburetor and an intake manifold, a passageway between said carburetor and said intake manifold for the flow of said fuel-air mixture therethrough, an atomizing member disposed generally transversely of said passageway, and laterally disposed aerodynamically configured means having an opening therethrough and completely supported by a foraminous member located in said passageway for creating a funnel-type flow pattern of said fuel-air mixture through said atomizing member in said passageway, said dynamically configured means forming a reinforced rim around the circumference of said opening and having one side facing opposite the direction of flow of said fuel air mixture through said passageway, said one side having substantially a curved aerodynamically curved configuration, said aerodynamically configured means allowing maximum flow of fuel-air mixture through said carburetor resulting in greater fuel economy and abatement of the discharge of pollutants.
Claim 2
Dependent Claim
152 words
In an apparatus for atomizing a fuel-air mixture in an internal combustion engine having a a carburetor and an intake manifold, a passageway between said carburetor and said intake manifold for the flow of said fuel-air mixture therethrough, an atomizing member disposed generally transversely of said passageway, and laterally disposed aerodynamically configured means having an opening therethrough and completely supported by a foraminous member located in said passageway for creating a funnel-type flow pattern of said fuel-air mixture through said atomizing member in said passageway, said dynamically configured means forming a reinforced rim around the circumference of said opening and having one side facing opposite the direction of flow of said fuel air mixture through said passageway, said one side having substantially a curved aerodynamically curved configuration, said aerodynamically configured means allowing maximum flow of fuel-air mixture through said carburetor resulting in greater fuel economy and abatement of the discharge of pollutants.
Claim 3
Dependent Claim
12 words
The apparatus of claim 1 wherein said foraminous element is substantially flat.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 wherein said foraminous element includes a dished depression configuration.
Claim 5
Dependent Claim
32 words
The apparatus of claim 1 wherein said laterally disposed aerodynamically configured means which creates a funnel-type flow pattern of said fuel-air mixture, lies in plane normal to the axis of said passageway.
Claim 6
Dependent Claim
19 words
The apparatus of claim 4 wherein said aperture and aerodynamically configured means are centrally disposed in said atomizing member.
Claim 7
Dependent Claim
20 words

Claim 8
Dependent Claim
15 words
The apparatus of claim 1 wherein said means forming a reinforced rim comprises a grommet.
Claim 9
Dependent Claim
105 words
An atomizing member to be disposed in the fuel-air mixture flow path between the carburetor and intake manifold of an internal combustion engine comprising: a foraminous element means for positioning said foraminous element in said flow path; and an opening through said foraminous element, a reinforced rim around the circumference of said opening having a substantially curved aerodynamically curved configuration on one surface thereof to face the flow path of said air fuel mixture; said reinforced rim completely supported by said foraminous member and creating a funnel type flow pattern of said air fuel mixture through said foraminous element when positioned in said flow path.
Claim 10
Dependent Claim
105 words
An atomizing member to be disposed in the fuel-air mixture flow path between the carburetor and intake manifold of an internal combustion engine comprising: a foraminous element means for positioning said foraminous element in said flow path; and an opening through said foraminous element, a reinforced rim around the circumference of said opening having a substantially curved aerodynamically curved configuration on one surface thereof to face the flow path of said air fuel mixture; said reinforced rim completely supported by said foraminous member and creating a funnel type flow pattern of said air fuel mixture through said foraminous element when positioned in said flow path.
Claim 11
Dependent Claim
16 words
The atomizing member of claim 8 wherein: said foraminous element includes an aperture centrally disposed therein.
Claim 12
Dependent Claim
23 words
The atomizing member of claim 8 wherein said aerodynamically configured means is located at a distance from the center of said foraminous element.
Claim 13
Dependent Claim
16 words
The apparatus of claim 8 wherein said foraminous element is formed in a dished depression configuration.
