Abstract

Abstract A fuel economizer device adapted to be interposed between the usual carburetor and manifold of an internal combustion engine, or the like, for substantially vaporizing the fuel prior to discharge thereof into the manifold and comprising a plate member having a plurality of spaced apertures for passing the fuel therethrough, said plate being disposed in relation to the manifold for being heated thereby during operation of the engine whereby fuel impinging thereon is substantially vaporized. In addition, a plurality of spaced detents or indentations are provided on the leading face of the plate for an accumulation of liquid fuel therein which has not been vaporized. The fuel trapped in the indentations is heated to the boiling point thereof which results in a substantially complete vaporization of the fuel stream prior to discharge thereof into the manifold for distribution to the combustion chamber.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 127 words
In combination with a carburetor and manifold, a fuel economizer device comprising an apertured plate member adapted to be interposed between the carburetor and manifold for passing an air-fuel mixture therebetween, said plate member being constructed of a heat conductive material for transmitting heat to the air-fuel mixture passing thereacross whereby substantially all of the air-fuel mixture is vaporized, and wherein the plate member comprises a substantially flat plate constructed of said heat conductive material, a plurality of randomly spaced perforations provided in said plate member for passage of the air-fuel mixture directly therethrough into said manifold, and a plurality of randomly spaced detents provided on the leading face of the plate member for receiving quantities of the air-fuel mixture therein for additional heating and vaporization thereof.
Claim 2
Dependent Claim 127 words
In combination with a carburetor and manifold, a fuel economizer device comprising an apertured plate member adapted to be interposed between the carburetor and manifold for passing an air-fuel mixture therebetween, said plate member being constructed of a heat conductive material for transmitting heat to the air-fuel mixture passing thereacross whereby substantially all of the air-fuel mixture is vaporized, and wherein the plate member comprises a substantially flat plate constructed of said heat conductive material, a plurality of randomly spaced perforations provided in said plate member for passage of the air-fuel mixture directly therethrough into said manifold, and a plurality of randomly spaced detents provided on the leading face of the plate member for receiving quantities of the air-fuel mixture therein for additional heating and vaporization thereof.
Claim 3
Dependent Claim 57 words
In combination with a carburetor and manifold, a fuel economizer device as set forth in claim 1 wherein the plate member is secured in communication with the "hot spot" of the manifold for receiving heat therefrom and for depositing the substantially completely vaporized air-fuel mixture into the manifold at the "hot spot" area for increased vaporization thereof.
Claim 4
Dependent Claim 30 words
In combination with a carburetor and manifold, a fuel economizer device as set forth in claim 1 wherein the spaced apertures and detents are centrally disposed in said plate member.
