Abstract
Abstract A system for gasifying a mixture of fuel, air and recycling exhaust gases for induction into an internal combustion engine, comprising means interconnected between extant fuel pump and engine carburetor to preheat the mixture by bleeding heat from a heat generator to the flow line between pump and carburetor for preheating said flow line and of utilizing the heating media in the carburetion process and optionally secondarily heating said carbureted mixture in the generator sequentially of introduction of the preheated fuel to the carburetor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
The combination with an internal combustion engine having fuel pump, carburetor input and output means and exhaust manifold, of fuel gasification apparatus comprising: A. a heat generator, said generator having connection with the exhaust manifold whereby the exhaust manifold may provide heated gases of exhaust to the generator, said heat generator being also interconnected with the fuel pump and carburetor; B. a fuel conduit having at least two adjoining sections connecting the fuel pump to the carburetor whereby to supply the carburetor with fuel; and C. at least two corresponding heat flow conduit sections emanating from the generator and encompassing the respective fuel conduit sections in heat exchange relation thereto, whereby to heat the fuel during its course from the pump to the carburetor, said heat flow and fuel conduits having connection with the carburetor in complemental disposition to each other, whereupon generation of exhaust from the engine the exhaust heat flow passes into said heat flow conduit sections resulting in the liquid fuel being preheated and gasified, and to the carburetor to combine with air in the carburetion mode.
Claim 2
Dependent Claim
180 words
The combination with an internal combustion engine having fuel pump, carburetor input and output means and exhaust manifold, of fuel gasification apparatus comprising: A. a heat generator, said generator having connection with the exhaust manifold whereby the exhaust manifold may provide heated gases of exhaust to the generator, said heat generator being also interconnected with the fuel pump and carburetor; B. a fuel conduit having at least two adjoining sections connecting the fuel pump to the carburetor whereby to supply the carburetor with fuel; and C. at least two corresponding heat flow conduit sections emanating from the generator and encompassing the respective fuel conduit sections in heat exchange relation thereto, whereby to heat the fuel during its course from the pump to the carburetor, said heat flow and fuel conduits having connection with the carburetor in complemental disposition to each other, whereupon generation of exhaust from the engine the exhaust heat flow passes into said heat flow conduit sections resulting in the liquid fuel being preheated and gasified, and to the carburetor to combine with air in the carburetion mode.
Claim 3
Dependent Claim
59 words
The apparatus according to claim 1, wherein the respective heat flow conduits have output ends at the generator and input ends adjacent the carburetor, the output ends of the respective heat flow conduits joins together adjacent the carburetor to feed the carburetor and means thereon adjacent the carburetor to regulate the flow of the exhaust gases to said carburetor.
Claim 4
Dependent Claim
37 words
The apparatus according to claim 1, wherein the carburetor outlet is in heat exchange disposition relative to the generator, said generator including at least one post-carburetion chamber connecting the carburetor to the fuel intake of the engine.
Claim 5
Dependent Claim
37 words
The apparatus according to claim 2, wherein the carburetor outlet is in heat exchange disposition relative to the generator, said generator including at least one post-carburetion chamber connecting the carburetor to the fuel intake of the engine.
Claim 6
Dependent Claim
44 words
The apparatus according to claim 3, wherein the post-carburetion chambers are two in number and trap means connecting the respective post-carburetion chambers exteriorly of the post-carburetion chambers, effecting thereby a simultaneous transfer of the gasified fuel from the carburetor while condensing ungasified liquids thereof.
Claim 7
Dependent Claim
51 words
The apparatus according to claim 5, wherein the respective heat flow conduits have output ends at the generator and input ends adjacent the carburetor, the output ends of the respective heat flow conduits joining together adjacent the carburetor and means thereon to regulate the flow of exhaust gases adjacent said carburetor.
