DETAILED DESCRIPTION OF THE INVENTION

[0017] With reference to FIGS. 1 to 3, there is representatively illustrated an oxy-hydrogen gas generating system 10 constructed according to an embodiment of the invention. In FIG. 1, system 10 is shown installed in a vehicle 12, such as, for example, in the vehicle's trunk, and is connected to the vehicle's internal combustion engine 14 to delivery hydrogen gas, oxy-hydrogen gas, or a mixture of both, (hereinafter fuel gas), to the engine.

[0018] Turning to FIGS. 2 and 3, system 10 includes a fluid vessel 16. It is important to note that the fluid vessel 16 is only diagrammatically represented and may take on various forms. For example, the interior of the vessel may be divided into two or more compartment or chambers that may or may not be sealed from one another. Further, one of skilled in the art will appreciate that the vessel could have various shapes and is not limited to the rectangular configuration that is representatively shown.

[0019] The fluid vessel 16 contains distilled water 18 and is only partially filed to allow a space 20 between the water and the top of the vessel to accommodate produced fuel gas. As discussed above, distilled water has a low electrical conductivity. An important aspect of the invention is to suspend graphene powder within the distilled water to provide electrically conductivity to the distilled water. An advantage of using graphene powder over conventional electrolytes is that the graphene does not bond with the water. Because graphene does not bond with water and because the water is distilled, only pure hydrogen gas and oxygen gas is produced during electrolysis. The advantage of this being that the product of combustion is water vapor free of any undesirable contaminants.

[0020] With continued reference to the FIGS. 2 and 3, a circulation pump 24 is connected to the vessel 16 and operates to circulate water 18 to suspend the graphene in the water. Electrodes 22a and 22b are disposed in the interior of the vessel at a spaced apart distance and are submerged in the water 18. Preferably the electrodes are located toward the bottom of the vessel 16 to prevent contact with the fuel gas. A power source 26, such as an electrical battery or alternator is operatively connected to the electrodes 22a and 22b via a switch 28. Switch 28 is operated to conduct electricity from the power source 26 to the electrodes 22a and 22b to cause electrolysis of water 18 having graphene particles suspended therein. In some instances, the original alternator of a vehicle may be replaced with an alternator having a higher amperage to increase electrical power to the electrodes.

[0021] A programmable logic controller (PLC) 30 may be operatively connected to the pump 24 and the switch 28 and include programmed instructions to operate the pump and switch according to a desired control logic to produce fuel gas on demand through electrolysis of water 18. One or more fluid level sensors 32a and 32b may be provided to detect a level of water 18 within the vessel 16. The sensors 32a and 32 may operatively connected to the PLC 30, which operates to illuminate one or more indicator lights 34 and 36 to indicate the detected water level within the vessel 16.

[0022] Representatively, lights 34 and 36 can be multicolor LED and be illuminated in different colors to indicate the detected water level. For instance, a green light could indicate the vessel is full, a yellow light could indicate the vessel is not full, but also not empty, and a red light could indicate that the vessel is empty and needs to be refilled with distilled water 18. As shown, light 34 could be located on the dashboard 38 of a vehicle and light 36 could be located near a refill valve/neck 40. While not shown, the refill neck 40 is fluidically connected to the vessel 16 to refill the vessel. A one-way valve may be installed in this fluidic connection.

[0023] The vessel 16 is connected, preferably toward its top, to a gas line 42, which can be connected to an internal combustion engine to provide fuel gas from the vessel to the engine. A valve 44 may be disposed across the gas line 42 and operated to control the flow of fuel gas from the vessel 16 and through the gas line. Valve 44 may be operatively connected to the PLC 30, which operates to control opening and closing the valve. Additionally, a pump 46 may be connect to the gas line 42 and operated to pump fuel gas from the vessel 16 and through the gas line. The pump 46 may be operatively connected to the PLC 30, which operates to turn the pump 46 off and on.

[0024] As further shown, in the representative embodiment, the PLC 30 may be operatively connected to the electronic control unit 48 of an internal combustion engine 14. This is particularly useful if the engine is electronically controlled so that the volume and rate of fuel gas delivered to the engine from the vessel 16 is controlled to maintain a stochiometric combustion.

[0025] While not shown, in embodiments, a heater may be provided to ensure that the water 18 does not freeze. The heater can be controlled via the PLC 30 by a temperature sensor that operates to detect the ambient temperature and when the temperature falls below a setpoint, the PLC can turn the heater on.

[0026] In embodiments, system 10 can be used to provide hydrogen gas or oxy-hydrogen gas to an internal combustion engine as a fuel supplement. However, preferably, in a vehicle application, the vehicle is converted to run entirely on the oxy-hydrogen gas produced by the system 10. As part of this conversion, the conventional fuel tank, fuel pump, and fuel line may be removed or prevented from operating. Additionally, the air intake may be connected to line 44 and sealed against intaking ambient air and the fuel injector ports may be sealed.

[0027] Also, while not shown, an electrical plug may be provided that may be located behind the fuel door to connect a power cord to recharge the power source 26 if the power source is a battery and requires charging. Further, it will be apparent to one skilled in the art that additional safety features may be provided that prevent a flow of fuel gas if there is a vehicle collision.

[0028] Several embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
