Abstract
Abstract A liquid fuel gasifier in which the liquid fuel is heated by contact with an exhaust gas heat exchanger converting the liquid fuel to a gas. The gasified liquid fuel is then mixed with air prior to entering the engine. In one form of the device water is mixed with the gasified fuel air mixture prior to entering the engine to increase the octane rating.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
210 words
A fuel system for internal combustion engines comprising an exhaust pipe extending from said internal combustion engine, a chamber, said exhaust pipe extending through said chamber with said chamber sealed to said exhaust pipe, a hollow tube extending into said chamber and having an open end directed toward said exhaust pipe for directing liquid fuel against said exhaust pipe, conduits connected to the upper portion of said chamber for directing a flow of air through said chamber, a baffle extending generally horizontally in said chamber above said hollow tube and below said conduit for concentrating the exhaust pipe heat on the fuel while preventing the flow of air from contacting said exhaust pipe, said baffle being spaced from the sides of said chamber to permit fuel vaporized on said exhaust pipe to rise and mix with the air flowing through said chamber, a liquid fuel control valve connected to said hollow tube, a butterfly valve mouNted in the conduit extending to said chamber for controlling the flow of air through said chamber, manually adjustable mechanical means interconnecting said liquid fuel control and said butterfly valves to permit adjustment of the air/fuel ratio provided by said valves, and manually controlled means connected to said mechanical means for simultaneously controlling said valves.
Claim 2
Dependent Claim
210 words
A fuel system for internal combustion engines comprising an exhaust pipe extending from said internal combustion engine, a chamber, said exhaust pipe extending through said chamber with said chamber sealed to said exhaust pipe, a hollow tube extending into said chamber and having an open end directed toward said exhaust pipe for directing liquid fuel against said exhaust pipe, conduits connected to the upper portion of said chamber for directing a flow of air through said chamber, a baffle extending generally horizontally in said chamber above said hollow tube and below said conduit for concentrating the exhaust pipe heat on the fuel while preventing the flow of air from contacting said exhaust pipe, said baffle being spaced from the sides of said chamber to permit fuel vaporized on said exhaust pipe to rise and mix with the air flowing through said chamber, a liquid fuel control valve connected to said hollow tube, a butterfly valve mouNted in the conduit extending to said chamber for controlling the flow of air through said chamber, manually adjustable mechanical means interconnecting said liquid fuel control and said butterfly valves to permit adjustment of the air/fuel ratio provided by said valves, and manually controlled means connected to said mechanical means for simultaneously controlling said valves.
Claim 3
Dependent Claim
210 words
A fuel system for internal combustion engines comprising an exhaust pipe extending from said internal combustion engine, a chamber, said exhaust pipe extending through said chamber with said chamber sealed to said exhaust pipe, a hollow tube extending into said chamber and having an open end directed toward said exhaust pipe for directing liquid fuel against said exhaust pipe, conduits connected to the upper portion of said chamber for directing a flow of air through said chamber, a baffle extending generally horizontally in said chamber above said hollow tube and below said conduit for concentrating the exhaust pipe heat on the fuel while preventing the flow of air from contacting said exhaust pipe, said baffle being spaced from the sides of said chamber to permit fuel vaporized on said exhaust pipe to rise and mix with the air flowing through said chamber, a liquid fuel control valve connected to said hollow tube, a butterfly valve mouNted in the conduit extending to said chamber for controlling the flow of air through said chamber, manually adjustable mechanical means interconnecting said liquid fuel control and said butterfly valves to permit adjustment of the air/fuel ratio provided by said valves, and manually controlled means connected to said mechanical means for simultaneously controlling said valves.
Claim 4
Dependent Claim
210 words
A fuel system for internal combustion engines comprising an exhaust pipe extending from said internal combustion engine, a chamber, said exhaust pipe extending through said chamber with said chamber sealed to said exhaust pipe, a hollow tube extending into said chamber and having an open end directed toward said exhaust pipe for directing liquid fuel against said exhaust pipe, conduits connected to the upper portion of said chamber for directing a flow of air through said chamber, a baffle extending generally horizontally in said chamber above said hollow tube and below said conduit for concentrating the exhaust pipe heat on the fuel while preventing the flow of air from contacting said exhaust pipe, said baffle being spaced from the sides of said chamber to permit fuel vaporized on said exhaust pipe to rise and mix with the air flowing through said chamber, a liquid fuel control valve connected to said hollow tube, a butterfly valve mouNted in the conduit extending to said chamber for controlling the flow of air through said chamber, manually adjustable mechanical means interconnecting said liquid fuel control and said butterfly valves to permit adjustment of the air/fuel ratio provided by said valves, and manually controlled means connected to said mechanical means for simultaneously controlling said valves.
