Water Fuel Injection System
An injector system comprising an improved method and apparatus useful in the production of a hydrogen-containing fuel gas from water in a process in which the dielectric property of water and/or a mixture of water and other components determines a resonant condition that produces a breakdown of the atomic bonding of atoms in the water molecule. The injector delivers a mixture of water mist, ionized gases, and non-combustible gas to a zone or locus within which the breakdown process leading to the release of elemental hydrogen from water molecules occurs.
This invention relates to a method and apparatus useful in producing thermal combustive energy from the hydrogen component of water…
The invention of this present application represents a generational improvement in methods and apparatus useful in the utilization of water as a fuel source. In brief, the present invention is a microminiaturized water fuel cell and permits the direct injection of water, and its simultaneous transformation into a hydrogen-containing fuel, in a combustion zone, such as a cylinder in an internal combustion engine, a jet engine, or furnace. Alternatively the injection system of the present invention may be utilized in any non-engine application in which a concentrated flame or heat source is desired, for example, welding.
The present injection system eliminated the need for an enclosed gas pressure vessel in a hydrogen fuel system and thereby reduces a potential physical hazard heretofore associated with the use of hydrogen-based fuel. The system produces fuel on demand in real-time operation and sets up an integrated environment of optimum parameters so that a water-to-fuel conversion process works at high efficiency.
The preferred embodiment of the invention is more fully explained below with reference to the drawings in which:

Although I refer to an injector herein, the invention relates not only to the physical configuration of an injector apparatus but also to the overall process and system parameters determined in the apparatus to achieve the release of thermal energy. In a basic outline, an injector regulates the introduction into a combustion zone of process constituents and sets up a fuel mixture condition permitting combustion. That combustion condition is triggered simultaneously with injector operation in real time correspondence with control parameters for the process constituents.
In the fuel mixture condition that is created by the injector, water (H2O) is atomized into a fine spray and mixed with (1) ionized ambient air gases and (2) other non-combustible gases such as nitrogen, argon and other rare gases, and water vapor. (Exhaust gas produced by the combustion of hydrogen with oxygen is a non-combustible water vapor. This water vapor and other inert gases resulting from combustion may be recycled from an exhaust outlet in the injector system back into the input mixture of non-combustible gases). The fuel mix is introduced at a consistent flow rate maintained under a predetermined pressure. In the triggering of the condition created by the injector, the conversion process described in my patent # 4,936,961 and co-pending application serial # 07/460,859 is set off spontaneously on a micro level in a predetermined reaction zone. The injector creates a mixture, under pressure in a defined zone (or locus) of water, ionized gases and non-combustible gases. Pressure is an important factor in the maintenance of the reaction condition and causes the water mist/gas mixture to become intimately mixed, compressed, and destabilized to produce combustion when activated under resonant conditions of ignition. In accordance with the aforementioned conversion process of my patent and application, when water is subjected to a resonance condition water molecules expand and distend; electrons are ejected from the water molecule and absorbed by ionized gases; and the water molecule, thus destabilized, breaks down into its elemental components of hydrogen (2H) and oxygen (O) in combustion zone. The hydrogen atoms released from the molecule provide the fuel source in the mixture for combustion with oxygen. The present invention is an application of that process and is outlined in Table I:
The process occurs as water mist and gases are injected under pressure into, and intimately mixed in the combustion zone and an electrically polarized zone. In the electrically polarized zone, the water mixture is subjected to a unipolar pulsed direct current voltage that is tuned to achieve resonance in accordance with the electrical, mass and other characteristics of the mixture as a dielectric in the environment of the combustion zone. The resonant frequency will vary according to injector configuration and depends upon the physical characteristics, such as mass and volume of water and gases in the zone. As my prior patents and application point out, the resonant condition in the capacitive circuit is determined by the dielectric properties of water: (1) as the dielectric in a capacitor formed by adjacent conductive surfaces and (2) as the water molecule itself is a polar dielectric material. At resonance, current flow in the resonant electrical circuit will be minimized and voltage will peak.
The injector system provides a pressurized fuel mixture for subjection to the resonant environment of the voltage combustion zone as the mixture is introduced to the zone. In a preferred embodiment, the injector includes concentrically nested serial orifices, one for each of three constituent elements of the fuel mixture. (It may be feasible to combine and process non-combustible and ionized gases in advance of the injector. In this event only two orifices are required, one for the water and the other for the combined gases). The orifices disperse the water mist and gases under pressure into a conically shaped activation and combustion zone (or locus).
Figure 1A shows a transverse cross-section of an injector in which supply lines for water 1 ionized gas 2 and non-combustible gas 3 feed into a distribution disk assembly 4 having concentrically nested orifices. The fuel mixture passes through a mixing zone 5 and voltage zone 6 created by electrodes or conductive surfaces 7A and 7B (positive) and 8 (negative or ground). Electrical field lines are shown as 6A1 and 6A2 and 6B1 and 6B2. Combustion (i.e., the oxidation of hydrogen) occurs in the zone 9. Ignition of the hydrogen can be primed by a spark or may occur spontaneously as a result of the exceptionally high volatility of hydrogen and its presence in a high voltage field. Although a differentiation of the mixing zone, the voltage zone and the combustion zone is made in explaining the invention, that differentiation relates to events or conditions in a process continuum, and as is evident from Figure 1, the zones are not physically discrete. In the zone(s), there is produced an excited mixture of vaporized water mist, ionized gases and other non-combustible gases all of which have been instantaneously released fro under high pressure. Simultaneously. The released mixture is exposed to a pulsed voltage in the zone/locus at a frequency corresponding to electrical resonance. Under these conditions, outer shell electrons of atoms in the water molecule are destabilized and molecular time share is interrupted. Thus, the gas mixture in the injector zone is subjected to physical, electrical and chemical interactive forces which cause a breakdown of the atomic bonding forces of the water molecule.
Process parameters are determined based on the size of a particular injector. In an injector sized approximately for use to provide a fuel mixture to a conventional cylinder in a passenger vehicle automobile engine, the injector may resemble a conventional spark plug. In such an injector, the water orifice is 0.10 to 0.15 inch in diameter; the ionized gas orifice is 0.15 to .20 inch diameter; and the non-combustible gas orifice is 0.20 to 0.25 inch diameter. In such a configuration, the serial orifices increase in size from the innermost orifice, as appropriate to a concentric configuration. As noted above, the introduction of the fuel components is desirably maintained at a constant rate; maintenance of a back-pressure of about 125 pounds per square inch for each of the three fuel gas constituents appears satisfactorily useful for a spark-plug injector. In the pressurized environment of the injector, spring loaded one-way check valves in each supply line, such as 14 and 15, maintain pressure during pulse off times.
The voltage zone 6 surrounds the pressurized fuel mixture and provides an electrically charged environment of pulsed direct current in the range from about 500 to 20,000 or ore volts at a frequency tuned to the resonant characteristic of the mixture. This frequency will typically lie within the range of from about 20 KHz to about 50 KHz, dependent, as noted above, on the mass flow of the mixture from the injector and the dielectric property o the mixture. In a spark-plug sized injector, the voltage zone will typically extend longitudinally about 0.25 to 1.0 inch to permit sufficient dwell time of the water mist and gas mixture between the conductive surfaces 7 and 8 that form a capacitor so that resonance occurs at a high voltage pulsed frequency and combustion is triggered. In the zone, an energy wave is formed related to the resonant pulse frequency. The wave continues to pulse through the flame in the combustion zone. The thermal energy produced is released as heat energy. In a confined zone such as a piston/cylinder engine, gas detonation under resonant conditions produces explosive physical power.
In the voltage zone, the time share ration of the hydrogen and oxygen atoms comprising the individual water molecules in the water mist is upset in accordance with the process explained in my aforementioned Patent # 4,936,961 and application serial # 07/460,859. To wit, the water molecule which is itself a polar structure, is distended or distorted in shape by being subjected to the polar electric field in the voltage zone. The resonant condition induced in the molecule by the unipolar pulses upsets the molecular bonding of shell electrons such that the water molecule, at resonance, breaks apart into its constituent atoms. In the voltage zone, the water (H2O) molecules are excited into an ionized state; and the pre-ionized gas component of the fuel mixture captures the electrons released from the water molecule. In this manner at the resonant condition, the water molecule is destabilized and the constituent atomic elements of the molecule, 2H and O are released; and the released hydrogen atoms are available for combustion. The non-combustible gases in the fuel mixture reduce the burn rate of hydrogen to that of a hydrocarbon fuel such as gasoline or kerosene from its normal burn rate (which is approximately 2.5 times that of gasoline). Hence the presence of non-combustible gases in the fuel mixture moderates energy release and modulate the rate at which the free hydrogen and oxygen molecules combine in the combustion process.
The conversion process does not spontaneously occur and the condition in the zone must be carefully fine tuned to achieve an optimum input flow rate for water and the gases corresponding to the maintenance of a resonant condition. The input water mist and gases may likewise be injected into the zone in a physically pulsed [on/off] manner corresponding to the resonance achieved. In an internal combustion engine, the resonance of the electrical circuit and the physical pulsing of the input mixture may be required to be related to the combustion cycle of the reciprocating engine. In this regard, one or two conventional spark plugs may require a spark cycle tuned in correspondence to the conversion cycle resonance to that the combustion of the mixture will occur. Thus, the input flow, conversion rate and combustion rate are interrelated and optimally should each be tuned in accordance with the circuit resonance at which conversion occurs.
The injection system of the present invention is suited to retrofit applications in conventionally fueled gasoline and diesel internal combustion engines and conventionally fueled jet aircraft engines.
Figures 2A, 2B and 2C illustrate a type of injector useful, inter alia as a fuel source for a conventional internal combustion engine. In the cross-section of Figure 2A, reference numerals corresponding to identifying numerals used in Figure 1 show a supply line for water 1 leading to first distribution disc 1A and supply line for ionized gas 2, leading to second distribution disc 2A. In the cross-section, the supply line for non-combustible gas 3 leading to distribution disc 3A is not illustrated, however, its location as a third line should be self-evident. The three discs comprise distribution disc assembly 4. The supply lines are formed in an electrically insulating body 10 surrounded by electrically conductive sheath/housing 11 having a threaded end segment 12.
A central electrode 8 extends the length o the injector. Conductive elements 7A and 7B (7A and 7B depict opposite sides if the diameter in the cross-section of a circular body) adjacent threaded section 12 form, with electrode 8, the electrical polarization zone 6 proximate to combustion zone 9. An electrical connector 13 may be provided at the other end of the injector. (As used herein electrode refers to the conductive surface of an element forming one side of a capacitor). In the frontal view of Figure 2B it is seen that each disc comprising the distribution disc assembly 9, includes a plurality of micro-nozzles 1A1, 2A1, 3A1, etc., for the outlet of the water and gases into the polarization/voltage and combustion zones. The exploded view of Figure 2C shows another view of the injector and additionally depicts two supply line inlets 16 and 17, the third not being shown (because of the inability to represent the uniform 120 degree separation of three lines in a two-dimensional drawing).
In the injector, water mist (forming droplets in the range, for example, of from 10 to 250 microns and above, with size being related to voltage intensity) is injected into fuel-mixing and polarizing zone by way of water spray nozzles 1A1. The tendency of water to form a bead or droplet is a parameter related to droplet mist size and voltage intensity. Ionized air gases and non-combustible gases, introduced through nozzles 2A1 and 3A1, are intermixed with the expelling water mist to form a fuel-mixture which enters into voltage zone 6 where the mixture is exposed to a pulsating, unipolar high intensity voltage field (typically 20,000 volts at 50 KHz or above at the resonant condition in which current flow in the circuit [amps] is reduced to a minimum), created between electrodes 7 and 8.
Laser energy prevents discharge of the ionized gases and provides additional energy input into the molecular destabilization process that occurs at resonance. It is preferable that the ionized gases be subjected to laser (photonic energy) activation in advance of the introduction of the gases into the zone(s); although, for example, a fiber optic conduit may be useful to direct photonic energy directly into the zone. Heat generated in the zone, however, may affect the operability of such an alternative configuration. The electrical polarization of the water molecule and a resonant condition occurs to destabilize the molecular bonding of the hydrogen and oxygen atoms. By spark ignition, combustion energy is released.
To ensure proper flame projection and subsequent flame stability, pumps for the ambient air, non-combustible gas and water introduce these components to the injector under static pressure up to and beyond 126 psi.
Flame temperature is regulated by controlling the volume flow-rate of each fluid media in direct relationship to applied voltage intensity. To elevate flame temperature, fluid displacement is increased while the volume flow rate of non-combustible gases is maintained or reduced and the applied voltage amplitude is increased. To lower flame temperature, the fluid flow rate if non-combustible gases is increased and pulse voltage amplitude is lowered. To establish a predetermined flame temperature, the fluid media and applied voltage are adjusted independently. The flame pattern is further maintained as the ignited, compressed, and moving gases are projected from the nozzle-ports in distribution disc assembly 4 under pressure and the gas expands in the zone and is ignited.
In the voltage zone several functions occur simultaneously to initiate and trigger thermal energy yield. Water mist droplets are exposed to high intensity pulsating voltage fields in accordance with an electrical polarization process that separates the atoms of the water molecule and causes the atoms to experience electron ejection. The polar nature of the water molecule which facilitates the formation of minute droplets in the mist appears to cause a relationship between the droplet size and the voltage required to effect the process, i.e., the greater the droplet size, the higher the voltage required. The liberated atoms of the water molecule interact with laser primed ionized ambient air gases to cause a highly energized and destabilized mass of combustible gas atoms to thermally ignite. Incoming ambient air gases are laser primed and ionized when passing through a gas processor; and an electron extraction circuit (Figure 5) captures and consumes in sink 55 ejected electrons and prevents electron flow into the resonant circuit.
In terms of performance, reliability and safety, ionized air gases and water fuel liquid do not become volatile until the fuel mixture reaches the voltage and combustion zones. Injected non-combustible gases retard and control the combustion rate of hydrogen during gas ignition.
In alternate applications, laser primed ionized liquid oxygen and laser primed liquid hydrogen stored in separate fuel tanks can be used in place of the fuel mixture, or liquefied ambient air gases alone with water can be substituted as a fuel source.
The injector assembly is design variable and is retrofitable to fossil fuel injector ports conventionally used in jet/rocket engines, grain dryers, blast furnaces, heating systems, internal combustion engines and the like.
A flange mounted injector is shown in cross-section in Figure 3 which shows the fuel mixture inlets and illustrates an alternative (3) nozzle configuration leading to the polarization (voltage) and combustion zones in which one nozzle 31A, 32A and 33A for each of the three gas mixtures is provided, connected to supply lines 31 and 32 (33 not shown). Electrical polarization zone 36 is formed between electrode 38 and surrounding conductive shell 37. The capacitive element of the resonant circuit is formed when the fuel mixture, as a dielectric, is introduced between the conductive surfaces of 37 and 38. Figure 3A is a frontal view of the operative end of the injector.
Multiple injectors may be arranged in a gang as shown in Figure 4 in which injectors 40, 41, 42, 43, 4, 45, 46, 47, 48 and 49 are arranged concentrically in an assembly 50. Such a ganged array is useful in applications having intensive energy requirements such as jet aircraft engines, and blast furnaces.
The basic electrical system utilized in the invention is depicted in Figure 5 showing the electrical polarization zone 6 which receives and processes the water and gas mixture as a capacitive circuit element in a resonant charging circuit formed by inductors 51 and 52 connected in series with diode 53, pulsed voltage source 54, electron sink 55 and the zone/locus 6 formed from conductive elements 7 and 8. In this manner, electrodes 7 and 8 in the injector form a capacitor which has electrical characteristics dependent on the dielectric media (e.g., the water mist, ionized gases, and non-combustible gases) introduced between the conductive elements. Within the macro-dielectric media, however, the water molecules themselves, because of their polar nature, can be considered micro-capacitors.
Fuel distribution and management systems useful with the injector of this application are described in my co-pending applications for patent, PCT/US90/6513 and PCT/US90/6407.
A distribution block for the assembly is shown in Figure 6. In Figure 6 the distribution block pulses and synchronizes the input of the fuel components in sequence with the electrical pulsing circuit. The fuel components are injected into the injector ports in synchronization with the resonant frequency to enhance the energy wave pulse extending from the voltage zone through the flame. In the configuration of Figure 6, the electrical system is interrelated to distribution block 60, gate valve 61 and separate passageways 62, 63, and 64 for fuel components. The distributor produces a trigger pulse which activates a pulse shaping circuit that forms a pulse having a width and amplitude determined by resonance of the mixture and established a dwell time for the mixture in the zone to produce combustion.
As in my referenced application regarding control and management and distribution systems for a hydrogen containing fuel gas produced from water, the production of hydrogen gas is related to pulse frequency on/off time. In the system shown in Figure 6, the distributor block pulses the fluid media introduced to the injector in relationship to the resonant pulse frequency of the circuit and to the operational on/off gate pulse frequency. In this manner the rate of water conversion (i.e., the rate of fuel production by the injector) can be regulated and the pattern of resonance in the flame controlled.
