ABSTRACT:
TECHNICAL FIELD
This invention relates to motor vehicles powered by combustion engines and operable substantially pollution-free on given fuel gas.
BACKGROUND OF THE INVENTION
Combustion effluents of fossil fuels, such as coal, petroleum (including diesel oil, kerosene, jet fuel, and gasoline), and even natural gas, contain, in addition to customary carbon dioxide and water, undesirable hydrocarbon fragments and derivatives, often in particulate form, carbon monoxide, and gaseous oxides of nitrogen and/or of sulfur transformable to noxious droplet form (acid rain).
Hydrogen was long-considered an ideal fuel because convertible completely to water via air combustion. See century-old Eldridge U.S. Pat. No. 603,058 for an Electrical Retort wherein an air arc flashed water to steam then pyrolyzed it and electrode carbon. Yet hydrogen is unsatisfactory as fuel for an internal-combustion engine because it heats the intake valves—ahead of the combustion chamber—and causes pre-ignition flashback, which is deleterious to the engine operation and structure, and is conducive to emission of harmful nitrogen oxides (aptly: “NOx”) into the atmosphere. An instructive reference is

Many places are polluted by emissions from combustion of fossil fuels by motor vehicles, lawnmowers, heating systems, manufacturing plants, or electricity generation, despite many laws and safeguards. My invention is the first and (so far) only solution to the problem.
SUMMARY OF THE INVENTION
A primary object of the present invention is operation of motor vehicles without pollution of the environment.
Another object of this invention is to fuel combustion in such a way that it is substantially free of harmful emissions.
A further object of the invention is to enable substantially pollution-free operation of internal-combustion engines.
Yet another object of the invention is to enable motor vehicles to generate on-board fuel for electrical or mechanical motive power.
A still further object of the invention is to render production of electrical energy for use by motor vehicles more environmentally friendly than electrical generation customarily is nowadays.
A still further object of this invention is to accomplish the foregoing objects more economically than possible with fossil fuels, preferably taking into account environmental as well as other costs.
In general, the objects of this invention are attained using fuel gas combustible substantially completely to carbon dioxide and water vapor, usually in an internal-combustion engine or equivalent.
That fuel preferably is generated by underwater carbon arcing, wherein both carbon and water are pyrolyzed into gaseous condition and air-combustible to carbon dioxide and water, free of pollutants.
More particularly, motor vehicles are fueled according to this invention and thereby enabled to combust the fuel pollution-free and to be driven either directly through engine-produced motive power or indirectly by electricity generated by engine-produced motive power.
In addition, this invention enables vehicles with considerable fuel requirements to produce fuel gas on board—advantageous for sea transport vessels as well as for trans-continental trains or trucks.
