Abstract: A thermal liquid pump suitable for use as a fuel injector is described; when used as a fuel injector hypergolic combustion is possible. The pump includes a space or chamber that is connected to a fuel supply source. A check valve admits the fuel from the fuel supply into the chamber wherein an electrical heating coil heats the fluid within the chamber. The fuel confined in the chamber is not permitted to vaporize and the increasing temperature creates increasing pressure through thermal expansion of the fuel. A delivery valve is provided in the chamber that is electrically actuated to open and discharge the pressurized fuel into a combustion space. When an appropriate amount of fuel has been discharged, the delivery valve is closed and additional fuel is admitted to the chamber through the check valve.

Abstract: An internal combustion engine in which heat is derived from the engine cooling system and the exhaust to heat a working fluid and to transform it into a gas which drives a turbine which operates a generator. Direct current from the latter is delivered to an electrolysis cell containing purified water which is decomposed into hydrogen and oxygen. The oxygen is injected under pressure into the combustion chambers of the engine while the hydrogen is also injected under pressure into a carburetor where it is combined with conventional hydrocarbon fuel.

Abstract: 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.
