Fuel vaporizer

Claim 2

In a carburetor system for an internal combustion engine of the type including a carburetor having an air horn for channeling a main system of air through the carburetor; a venturi disposed within said air horn for receiving a limited system of air and mixing fuel therewith to form a venturi air-fuel mixture which upon passing thRough said venturi mixes with said main system of air passing through the air horn of the carburetor to form the final air-fuel mixture passing from the carburetor system; an electric fuel vaporizer assembly means disposed across the path of the venturi air-fuel mixture flow for vaporizing substantially only the venturi air-fuel mixture prior to the mixing thereof with said main system of air to form the final air-fuel mixture, said electric fuel vaporizer assembly comprising: electric heating means associated with said venturi and disposed across the path of the venturi air-fuel mixture flow for heating and vaporizing the venturi air-fuel mixture prior to mixing with said main system of air; means for mounting said heating and vaporizing means about said venturi directly in the path of the venturi air-fuel mixture; and electric circuit means for supplying electric power from an electric power source to said heating and vaporizing means for effectively vaporizing the venturi air-fuel mixture prior to mixing thereof with said main system of air.

Claim 3

The electric fuel vaporizer assembly of claim 1 wherein said heating and vaporizing means comprises a generally circular multi-turn heating coil having a center that normally aligns with the major axis of said venturi such that said heating coil generally gives off a uniform distribution of heat to the entire venturi air-fuel mixture passing through the venturi.

Claim 4

The electric fuel vaporizer of claim 2 wherein said mounting means for mounting said heating and vaporizing means about said venturi comprise an insulated frame structure means for receiving said heating and vaporizing means, and means for mounting said frame structure means directedly below said venturi.

Claim 5

The electric fuel vaporizer of claim 3 wherein said insulated frame structure means for receiving said heating and vaporizing means comprises a pair of spaced apart cross rod assemblies for receiving and sandwiching said heating and vaporizing means therebetween, and means for interconnecting said cross rod assemblies for holding the same in spaced apart relationship and retaining said heating and vaporizing means therebetween.

Claim 6

The electric fuel vaporizer of claim 4 wherein said cross rod assemblies and said means interconnecting such comprise an inner wire structure having a ceramic type coating formed thereon thereby giving rise to the insulated frame structure for receiving the heating and vaporizing means.

Claim 7

The electric fuel vaporizer of claim 5 wherein said electric circuit means includes control means for increasing the heat produced by said heating and vaporizing means in response to an increase in the air flow through said carburetor dictated by the engine associated with the carburetor system.

Claim 8

The electric fuel vaporizer of claim 6 wherein said control means includes: resistor means operatively connected in said electric circuit means; and a reverse vacuum switch circuit means connected in parallel with said resistor means for sensing changes in engine vacuum and for closing said vacuum switch circuit means and bypassing said resistor means as engine vacuum decreases beyond a predetermined value, thereby increasing the current flow through said electric circuit means and increasing the quantity of heat given off by said heating and vaporizing means.

Claim 9

A fuel vaporizing carburetor system for an internal combustion engine comprising: a. an air horn means for receiving a main system of air and channeling the main system of air through said carburetor; b. a venturi disposed within said air horn means for receiving a limited system of air and mixing fuel therewith to form a venturi air-fuel mixture which upon passing through said venturi mixes with said main system of air passing through said air horn to form a final air-fuel mixture; c. an insulated frame structure disposed immediately below said venturi; d. mounting means interconnecting said insulated frame structure with said venturi for securing said insulateD frame structure closely adjacent the lower portion of said venturi; e. electric heating and vaporizing means held by said insulated frame structure for heating and vaporizing the venturi air-fuel mixture prior to the same mixing with said main system of air to form the final air-fuel mixture; f. electric circuit means for supplying electric power from an electric power source to said heating and vaporizing means for effectuating vaporization of the venturi air-fuel mixture prior to mixing with said main system of air; and g. control means operatively associated with said electric circuit means for increasing the heat produced by said heating and vaporizing means in response to an increase in the air flow through said carburetor dictated by the engine associated with the carburetor system.

Claim 10

A fuel vaporizing carburetor system for an internal combustion engine comprising: a. an air horn means for receiving a main system of air and channeling the main system of air through said carburetor; b. a venturi disposed within said air horn means for receiving a limited system of air and mixing fuel therewith to form a venturi air-fuel mixture which upon passing through said venturi mixes with said main system of air passing through said air horn to form a final air-fuel mixture; c. an insulated frame structure disposed immediately below said venturi; d. mounting means interconnecting said insulated frame structure with said venturi for securing said insulateD frame structure closely adjacent the lower portion of said venturi; e. electric heating and vaporizing means held by said insulated frame structure for heating and vaporizing the venturi air-fuel mixture prior to the same mixing with said main system of air to form the final air-fuel mixture; f. electric circuit means for supplying electric power from an electric power source to said heating and vaporizing means for effectuating vaporization of the venturi air-fuel mixture prior to mixing with said main system of air; and g. control means operatively associated with said electric circuit means for increasing the heat produced by said heating and vaporizing means in response to an increase in the air flow through said carburetor dictated by the engine associated with the carburetor system.

Claim 11

The electric fuel vaporizer of claim 8 wherein said heating and vaporizing means includes an electric multi-turn circular coil held by said insulated frame structure; and wherein said insulated frame structure comprises an open type frame having a pair of spaced apart upper and lower cross rod assemblies held in spaces part relationship by a plurality of vertical post connected and extending between said cross rod assemblies, each cross rod assembly including two rods intersecting generally about the mid-point of each at general right angle to each other, the two rods of each cross rod assembly lying in substantially the same vertical plane as corresponding rods of the other rod assembly.
