摘要：

An internal combustion engine in which heat is derived from the engine cooling system and/or the exhaust to heat a working fluid in a closed circulatory system. This heat transforms the working fluid into a gas which is delivered to a turbine which drives a generator. The generator delivers DC current to an electrolysis cell in which water is decomposed. The water is decomposed by the electric current into its oxygen and hydrogen components. The oxygen is passed to the air intake of the engine carburetors, while the hydrogen is conveyed to a carburetor therefor. Also included is a carburetor for conventional hydrocarbon fuels. The two carburetors are connected by linkage which may be operated either manually or by pressure to vary the ratio of the carbureted fuels which are delivered to the engine. Certain auxiliary equipment is provided in the form of an air-cooled condenser in the working fluid system, a supply tank for the hydrocarbon fuel, which ordinarily is gasoline, a water supply tank, a tank for receiving hydrogen under pressure, a pump for the hydrocarbon fuel, a pump for the working fluid system, a pump for delivering water from the water tank to the electrolysis cell and a hydrogen pump which passes hydrogen to the hydrogen carburetor and/or the hydrogen tank. In a modification, power is derived from the engine exhaust to drive a turbo-generator which delivers DC current to the electrolysis cell. This current may be supplemented by that provided by a generator that is driven by a turbine powered by the working fluid of a system that is heated by the cooling system of the engine.
