Abstract: The present invention relates to a water vapor injection system for introducing artificially high humidity air into the carburetor of an internal combustion engine. Once delivered to the carburetor, the high humidity or moisture-laden air mixes with the air-fuel mixture normally passing from the carburetor into the combustion chambers to increase the combustion efficiency of the internal combustion engine.A forced air system is generated by an air injection pump, and this forced air is heated to alter its vaporization characteristics prior to being circulated through a water filled container. As the heated air is exposed to the water within the container, the air increases in moisture content as the heat associated with the air tends to vaporize water about the interface between respective bubbles and the surrounding water.

Abstract: In the art of motor fuel carburetion where conventional carburetors are employed to mix and prepare the fuel/air mixture for introduction into the combustion chamber of internal combustion engines, and particularly where gasoline is used as fuel, the liquid fuel is sucked, or aspirated out of the provided discharge opening by the current of intake air as it flows past this opening, thereby presumably mixing and preparing the fuel/air charge.In this invention the method of mixing liquid fuel with air employs a liquid fuel delivery spray valve which is so located as to spray liquid fuel upon an electrically heated metal plate which instantly converts the fuel from its liquid state into vapor form; a water delivery spray valve which is so located in similar fashion as the fuel delivery valve described above, to moderate the explosive violence of high octane fuel in the combustion chamber of internal combustion engines; and an electrically heated porous screen to atomize the fuel/air/steam mixture charge.

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 intake manifold of the internal combustion engine downstream from the usual air cleaner. A single device operating at a high temperature, for example 800.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: Water from a tank is drawn upward by suction created by the vacuum in the carburetor air cleaner or in the engine intake manifold through a filter containing synthetic sponge material sandwiched between upper and lower layers of glass wool, where it passes through a heat exchanger coil which is heated by being positioned adjacent the exhaust manifold of an internal combustion engine. There it is vaporized into steam and then passes either through an inlet port into the base of the engine carburetor or directly into the intake manifold. The steam thus produced expands and mixes with and vaporizes the unvaporized droplets of gasoline in the gasoline vapor, breaking up these droplets into gasoline vapor before they can enter the intake manifold.

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: This invention relates to a vaporific carburetor for a gasoline engine, consisting of an evaporator tube assembly inclined to the horizon, an auxiliary fuel tank assembly at the upper end of the evaporator tube assembly, a mixer tube assembly at the lower portion of the evaporator tube assembly and an auxiliary water tank connected by a small water pipe to the upper portion of the evaporator tube assembly.The vaporific carburetor differs from the vaporizer carburetor in four different aspects. The first difference is in the cut at the outlet of the high speed tube, and the position of the cut with respect to the venturi. In the vaporizer carburetor the said cut is perpendicular to the wall of the venturi while in the vaporific carburetor the said cut is parallel with the wall of the venturi. The second difference is in the connection of the inlet of the idling speed tube.

Abstract: A hot fuel gas generator for an internal combustion engine vaporizes gasoline and water in a heated pressure vessel and mixes the resulting superheated gaseous fuel with air in a metering valve which communicates with the internal combustion engine. A single device operating at a very high temperature, for example 1000.degree. F., is used for the simultaneous vaporization of the fuel and water to develop desirable working pressure and volume. The high temperature gaseous state of the fuel represents molecules at 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 gas produced therefore enables complete combustion and the elimination of the atmospheric pollutants common in the operation of internal combustion engines.

Abstract: Improved apparatus for injecting vapors, such as water vapor in the form of low temperature-low pressure steam, into the intake manifold of an internal combustion engine. A controlled flow of air is drawn through a vapor generator by the intake manifold vacuum and the resulting air-vapor mixture is discharged through a nozzle into the intake manifold. The vapor generator contains a level controlled body of liquid for forming the vapor. Air enters the generator at the bottom of the liquid and rises through the liquid past a heater and a dispersion member which disperses the air into small bubbles. The heater is operated from the engine cooling system and heats the air and liquid sufficiently for generating steam at the subatmospheric pressures available from the intake manifold. The resulting steam-air mixture is injected into the intake manifold for controlling combustion. In a modified embodiment, liquid is also injected directly into an engine carburetor during acceleration.

The fuel system therefore enables complete combustion and the elimination of the atmospheric pollutants common in the operation of internal combustion engines.

Abstract: For introducing water in vapor form to the intake manifold of a combustion engine use is made of a double walled heat exchanger. Exhaust from the engine is passed through the space between an inner wall and an outer wall and then returned to the exhaust pipe. A chamber within the inner wall provides a reservoir of water and accommodates a float to control the level. For transporting vapors to the intake manifold of a combustion engine, a vacuum line from the intake manifold is in communication with the chamber at a location above the water level and induces air to flow through an air intake to a location adjacent the bottom of the water reservoir, releasing large bubbles of air below a dispersing plate through which a plurality of streams of small bubbles emerge bubbling to the surface, and entrain hot water vapor.
