Abstract: A fuel system for an internal combustion engine of the piston type vaporizes a liquid fuel and water and mixes the resulting gaseous fuel and water vapor with air in a metering valve which communicates with the internal combustion engine. A device operating at a very high temperature, for example 1800.degree. F. is used in the vaporization of the fuel. The high temperature gaseous state of the fuel represents molecules of the greatest degree of separation from each other providing the greatest opportunity for contact of the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction. The fuel system therefore enables complete combustion and the elimination of the atmospheric pollutants common in the operation of internal combustion engines.

Abstract: Waste-gas suppressor for internal-combustion engines, utilizing negative pressure generated in the carburetor of the engine. A flow-regulator valve operated by the negative pressure adjusts water flow in proportion to engine speed, the water being evaporated by the exhaust heat of the engine. The resulting steam is supplied to the combustion chamber of the engine.

Abstract: An apparatus for injecting steam into an internal combustion engine including an exhaust manifold and an intake manifold, which has a control valve which receives and controls a flow of water supplied from a source or reservoir of same, and from which the flow of water controlled by the valve is delivered to an evaporator adapted to receive the exhaust gases of the engine and to convert the water passing therethrough into steam, which is thereafter delivered to the intake manifold of the internal combustion engine, increasing the engine power and reducing the contaminants in the exhaust gases therefrom.

Abstract: A steam generator is provided in operative association with a source of water and the exhaust system of a combustion engine including an air induction system provided with primary fuel inlet structure and supplemental fuel inlet structure. The steam generator derives its heat for converting water into steam from the exhaust system of the combustion engine and the steam generator includes a steam outlet communicated with and opening into one end of an elongated tubular housing disposed in good heat transfer relation with the exhaust system of the combustion engine and having a gas outlet at its other end communicated with the supplemental fuel inlet of the induction system.

Abstract: The present invention is directed to a method of and an apparatus for producing mixture gases of three elements such as water vapor, fuel oil and air to be combusted in the combustion chamber of an internal combustion engine. The mixture elements, particularly water vapor, are heated so that they may be mixed in vapor phase while passing through passageways provided to absorb a heat generated in the combustion stroke of the engine. Under controlled combustion conditions, the mixture of these three elements may be fully combusted in the combustion chamber of the engine, whereby a large quantity of water may be applied to a fuel mixture as a substantial part thereof, thus resulting in a remarkable improvement in the fuel consumption or the output per unit of fuel oil in the internal combustion engine.

Abstract: Apparatus for supplying an air-vapor mixture to an air intake chamber in communication with an air intake passageway of a carburetor under acceleration conditions of an internal combustion engine. The air intake chamber has a valved inlet opening through which normal atmospheric air is supplied to the carburetor under normal operating conditions. Upon operation of the accelerator control means, a steam or vapor operated air injection means is actuated. The steam or vapor is admixed in the air injector nozzles with the mixture being discharged into the air intake chamber. This increases the pressure in the chamber causing the valve in the atmospheric air inlet to close. The air-vapor mixture then becomes the sole air supply to the air intake passage of the carburetor.

Abstract: A hot fuel gas generator for an internal combustion engine simultaneously vaporizes gasoline and water in a multi-chambered heated pressure vessel having built in regulators for controlling pressure and volume and delivers the resulting superheated steam and gaseous fuel to the internal combustion engine downstream from the usual carburetor. A single device operating at a very high temperature, for example 1600.degree. F., is used for the simultaneous vaporization of the fuel and water to develop desirable working pressure and volume. The high temperature steam and gaseous fuel positions the fuel molecules at the greatest degree of separation from each other providing the greatest opportunity for contact of the oxygen, the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction.

Abstract: Method and device for restraining nitrogen oxide production in combustion gas of internal combustion engines, comprising feeding a suitable quantity of steam into cylinder of internal combustion engine and mixing the steam in fuel-air mixture.
