Abstract
Abstract A pollution-free combustion engine and method of operating same, and a unique fuel, in which the working fluid for the engine is a liquid alkali metal reacted with water, the reacted alkali metal and water producing hydrogen, an hydroxide of the alkali metal, and heat, at least a portion of the hydroxide being exhausted to atmosphere where it reacts with carbon monoxide to produce a harmless carbonate, said fuel thus resulting in a nonpolluting engine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
25 words
A combustion engine as in claim 1, wherein said reaction chamber comprises a cylinder, and said driven member comprises a piston reciprocable in the cylinder.
Claim 2
Dependent Claim
35 words
A combustion engine as in claim 2, wherein said engine includes a crankcase, said power output shaft comprising a crankshaft rotatable in said crankcase, and connecting rod means connected between said crankshaft and said piston.
Claim 3
Dependent Claim
95 words
A combustion engine as in claim 3, wherein a cylinder head is on the housing closing one end of the cylinder of the engine, intake and exhaust valves in said cylinder head for controlling the flow of air and water to the chamber of said engine and for controlling the flow of exhaust from said chamber, an injection nozzle in said head for injecting measured amounts of a liquid alkali metal into said chamber in timed relationship with the admission of air and water thereinto to react the alkali/metal with the water in the chamber.
Claim 4
Dependent Claim
75 words
A combustion engine as in claim 4, wherein said alkali metal is contained in a reservoir, said reservoir mounted closely adjacent said cylinder so that heat generated in the cylinder during use of the engine maintains the alkali metal in liquid form. 6. A combustion engine as in claim 2, wherein said engine is a four cycle engine and said piston has an intake stroke, a compression stroke, a power stroke, and an exhaust stroke.
Claim 5
Dependent Claim
89 words
A combustion engine as in claim 4, wherein an intake manifold is connected to said cylinder head, a carburetor on said intake manifold, an air inlet in said carburetor, a water inlet in said carburetor, a conduit means connected to said water inlet and to a tank containing water for supplying water to said carburetor and thus to said engine, a tank containing a liquid alkali metal, conduit means connected to said tank and to said injection nozzle for supplying liquid alkali metal from said tank to said engine.
Claim 6
Dependent Claim
42 words
A combustion engine as in claim 6, wherein exhaust means is in said cylinder for exhausting an hydroxide of the reacted alkali metal from the chamber of the engine during a portion of the power stroke and exhaust stroke of said engine.
Claim 7
Dependent Claim
42 words
A combustion engine as in claim 7, wherein heater means is disposed in operative relationship with said tank containing alkali metal and said conduit means connected with said tank and with said injection nozzle for maintaining the alkali metal in liquid form.
Claim 8
Dependent Claim
53 words
A combustion engine as in claim 9, wherein conduit means is connected between said chamber and the crank case of said engine for conducting the hydroxide of the reacted alkali metal from the chamber into the crank case and thence into a storage tank, said hydroxide serving as a lubricant for said engine.
Claim 9
Dependent Claim
13 words
A combustion engine as in claim 10, wherein said alkali metal comprises sodium.
Claim 10
Dependent Claim
13 words
A combustion engine as in claim 10, wherein said alkali metal comprises lithium.
Claim 11
Dependent Claim
13 words
A combustion engine as in claim 10, wherein said alkali metal comprises potassium.
