Applicant hereby states that a basis for special status comprises greenhouse gas reduction as well as other “green technologies” as will be apparent upon reading this application. As is set out infra, Applicant has a working system and method for greenhouse gas reduction with a water electrolyzer by introducing oxyhydrogen into an engine. Accordingly the Applicant hereby petitions for acceptance into the Green Technology Pilot Program.
This disclosure relates generally to a water electrolyzer system and water electrolysis method for internal combustion engines. The term “electrolyzer” refers to an apparatus capable of decomposing a chemical compound by electrolysis. For purposes of this disclosure, said chemical compound undergoing electrolysis will be water. It is understood that generally available water (tap water, bottled water, distilled, or similar) is not strictly H2O, but a compound comprising a variety of elements in addition to hydrogen and oxygen. Nonetheless, “water” is intended to refer to said generally available water which may or may not be strictly H2O.
Water is the most abundant compound on the surface of the earth. The water molecule is comprised of two hydrogen atoms, one oxygen atom and other trace elements of both positive and negative charges. It is the trace elements that provide the capacity of water to be a conductor of electricity. The electrolysis process is frequently utilized for the generation of gases by a decomposition process where electrodes of opposite charge (comprising a negative charged electrode, or “cathode”, and a positive charged electrode, or “anode”) are immersed in an electrically conductive electrolyte with an electrical charge running between the electrodes. In one embodiment, opposite current charge causes the HHO molecule to change its structure where the positive charged hydrogen atom is off-gassed at the negative charged electrode and the negative charged oxygen atom is off-gassed at the positive charged electrode. In one embodiment, elements can recombine to comprise a monoatomic and/or a diatomic hydrogen and/or oxygen compound sometimes called oxyhydrogen (also known as “hydroxyl”). In one embodiment, oxyhydrogen can comprise a mixture of hydrogen (H2) and oxygen (O2) gases, typically in a 2:1 molar ratio. In one embodiment, a ratio of 4:1 or 5:1 hydrogen:oxygen is required to avoid an oxidizing flame.
Water electrolyzer systems for use in internal combustion engines and other industrial processes are well known. Early pioneers used electrolysis to separate and collect the gases for individual use. Mr. Raymond Henes and Mr. William Rhodes (U.S. Pat. No. 3,262,872) (hereafter “Henes”) disclosed the use of a single duct feed system of a mixed atomic hydrogen and oxygen as a fuel source. Henes' fuel was used as a source for welding/torch applications, but demonstrated use of hydrolysis of water as an energy source.
Likewise, Mr. Yull Brown (U.S. Pat. No. 4,014,777) further explored the electrolysis process as claimed a new combine gas formed name Brown's gas. Only later was electrolysis of water explored as a fuel gas. For example, Mr. Stanley A. Meyer (U.S. Pat. Nos. 4,936,961 and 5,293,857), explored the use of pulsating and electric field to liberate the gases of hydrogen and oxygen from water to be collected as a fuel gas. Meyer refers to a fuel cell water capacitor. Further, Meyer concentrated on an electrical control device to adjust the frequency to facilitate the electrolysis process.
Naturally, safety of water hydrolysis should be a central concern. Among the prior disclosures, most assume the electrolyzer produces a mixed gas on a safe, reliable consistent process.
Mr. Bill Ross (U.S. Pat. No. 6,209,493) discloses a system using an electrolysis cell for generating one or more combustible gases from an electrolytic solution. Ross discusses many control devices, but does not disclose the main operating parameters of voltage and current (Amperage). Further, Ross fails to disclose the conductive strength of electrolyte and the effects of current draw from direct current sources. As typical of many prior disclosures, current systems have very little spare amperage capacity. Consequently, overuse of a direct current supply can cause severe electrical systems.
In one embodiment, it can be advantageous to control a power source coming into a water electrolyzer. Defining workable parameters on said power source is a goal of many prior art examples, but their approaches fall short.
Mr. Harvath (U.S. Pat. No. 3,954,592) discloses an electrical supply means to apply pulses of electrical energy between an anode and a cathode of one or more cells. Likewise, Mr. John R. Hallenbeck (U.S. Pat. No. 7,762,218) discloses a power source comprising an electrometric net energy radiator having a frequency between 620 Hertz and 100,000 Hertz. Neither Harvath nor Hallenbeck overcome shortcomings regarding materials and cooling issues associated with water electrolysis. As discussed infra.
Hallenbeck (see supra) discloses a cell with two electrodes, one made of nickel oxide-hydroxide and another formed from a metal selected from the group consisting of nickel, tin, iron, lead, and combinations thereof. Accordingly, cells comprising electrodes of differing materials have been disclosed in the prior art. Nonetheless, Hallenbeck falls short in practice.
First of all, Hallenbeck does not provide a means of preserving a cathode during water electrolysis. Use of differing materials for said two electrodes does not preserve a cell during electrolysis. Further provisions must be provided to protect said cells and to operate said water electrolyzer in a safe reliable manner, as will be disclosed and claimed infra.
A side product in many water electrolyzer embodiments is the production of steam. Dealing with this side effect is an important matter.
Mr. Chou (U.S. Pat. No. 6,740,436) discloses a water cooling system. However Chou's cooling system requires a source of ice water to function. This approach leaves much to be desired since ice water is cumbersome and difficult to keep replenished in a motor vehicle. Likewise, Mr. Webster (U.S. Pat. No. 4,344,831) discloses a cooling system but does not introduce a means for controlling said cooling system when an electrolyte reaches a heat threshold where a steam (or other side effect) will be produced. Mr. Klein (U.S. Pat. No. 6,866,756) discloses a heat sink means for removing an excess heat generated by the electrolyzer. Said heat sink means leaves much to be desired however. First, it does not respond to heat production within said electrolyzer to the point of cutting off functionality of said electrolyzer when heat gets out of control. Further, it does not sense when steam production conditions have been reached.
Mr. Huang (U.S. Pat. No. 7,921,831) discloses a heat dissipation unit and one or more filters for separating water vapor. Huang, however, only filters said water vapor it does not prevent it from being produced within said water electrolyzer. Accordingly, Huang allows said water electrolyzer to reach high temperatures without controlling said temperature of said water electrolyzer.
None of these cooling systems present the advantages disclosed in this application infra.
Construction and methods of use of one or more cells within a water electrolyzer is a critical matter. Much effort has been spent devising a perfect material combination for said water electrolyzers. Typical of many different water electrolyzers, Mr. Mosher (U.S. Pat. No. 4,023,545) discloses a water electrolyzer with electrode cells comprising an anode and a cathode. However, like many water electrolyzers, Mosher does not provide different materials for said anode and said cathode.
Cells comprising electrodes of different materials are know as well, but do not use advantageous material combinations. Hallenbeck (see supra) discloses a cell with two electrodes, one made of nickel oxide-hydroxide and another formed from a metal selected from the group consisting of nickel, tin, iron, lead, and combinations thereof. Mr. Kucherov (U.S. Pat. No. 5,632,870) discloses an anode and a cathode comprising different materials; wherein, said cathode comprises a material consisting of Ni, Fe, Pd, Pt and Ir. Hallenbeck and Kucherov, however, fall short in practice since neither provides a means of preserving a cathode during water electrolysis. In practice, these electrodes undergo rapid decay during electrolysis. Further provisions must be provided to protect said cells and to operate said water electrolyzer in a safe reliable manner, as will be disclosed and claimed infra
Prior disclosures fail to disclose a means of maintaining the integrity of an electrolyzer through a longer period of use. Further, they leave much to be desired in safely operating an electrolyzer in proximity to an internal combustion engine.
Prior disclosures, when put into practice, have many shortcomings which this disclosure seeks to address. Prior embodiments comprise an electrolysis process which can draw too much current (thereby eliminating efficiency gains), fail to address overheating issues (which can damage engines and electrolyzers alike), and can dissolve electrode materials and wiring (leading to a loss of operation requiring major maintenance).
Simply put: prior embodiments of water electrolyzers fail to safely and consistently provide fuel gas for internal combustion engines. Therefore, they fail to provide the benefit of reducing exhaust emissions of greenhouse gases and improving efficiency of internal combustion engines over long periods of operation. It is therefore desired to fulfill the promise of electrolysis of water with internal combustion engines.
None of the above inventions and patents, taken either singularly or in combination, is seen to describe the instant disclosure as claimed. Accordingly, an improved water electrolyzer system and water electrolysis method for internal combustion engines would be advantageous.
Two water electrolyzer systems and a water electrolysis method for internal combustion engines are disclosed.

In one embodiment, sensor 120 is capable of measuring an internal temperature of water electrolyzer 100 and reporting said internal measurement to controller 122. In one embodiment, controller 122 can send an off signal when said internal measurement reaches a threshold temperature. In one embodiment, said “off signal” from controller 122 can cause current from battery 102 to stop flowing toward water electrolyzer 100. In one embodiment, controller 122 can engage cooling system 106 to further regulate said internal temperature of said water electrolyzer 100.
In one embodiment, water electrolyzer 100 can receive a source of direct current. In one embodiment, said source of direct current can comprise a power output from an alternator. In one embodiment, said alternator can be attached to an engine or generator. In another embodiment, said source of direct current can comprise battery 102. In one embodiment, water electrolyzer 100 can receive a pulsed direct circuit from battery 102. In one embodiment, said pulsed direct circuit can pass through a relay switch 124. In one embodiment, relay switch 124 can control said pulsed direct circuit and thereby trigger an on-off operation of water electrolyzer 100. In one embodiment, said pulsed direct circuit can be protected by a fuse 126. In one embodiment, fuse 126 can prevent an over leap of electric current and thereby prevent damage to PWM 104. In one embodiment, PWM 104 can comprise an advanced (brand) pulse width modulator unit. In one embodiment, fuse 126 can comprise a 15 amperage fuse. In one embodiment, water electrolyzer 100 can operate on 5-15 amps.
In one embodiment, PWM 104 can comprise a “Pulse Width Modulator”. In one embodiment, PWM 104 can comprise an electronic device between battery 102 and water electrolyzer 100 capable of providing a pulse width modulated direct current electricity. In one embodiment, said pulse width modulated direct current electricity can comprise a current comprising constant pulse width. In one embodiment, battery 102 and PWM 104 can provide a source of pulse width modulated direct current electricity.
In one embodiment, battery 102 can comprise a positive terminal 103a and a negative terminal 103b. In one embodiment, PWM 104 can comprise a positive input terminal 105a, a negative input terminal 105b, a positive output terminal 105c, and a negative output terminal 105d.

In one embodiment, PWM 104 can keep an average current at a set point, independent of the supply voltage or load. Internal components of PWM 104 can include resistors, capacitors, transistors and other components. In one embodiment, said frequency is set between 50 Hertz to 80 Hertz.

In one embodiment, negative output terminal 105d can attach to negative terminal 118. In one embodiment, said pulsed direct circuit can comprise battery 102 connected to PWM 104, and PWM 104 connected to water electrolyzer 100.
In one embodiment, water electrolyzer 100 can produce gases 110. In one embodiment, gases 110 are fed through feed line 108 to air intake system 112 of engine 114. In one embodiment, gases 110 can comprise a mixture of hydrogen, oxygen and other elements. In one embodiment, gases 110 can comprise oxyhydrogen (also known as “hydroxyl”), as discussed supra.
In many embodiments, modern internal combustion engines have a fuel management system controlled by many sensors that relay information to an engine computer. Said fuel management systems can control operational parameters, such as an air-to-fuel ratio, of engine 114. Said fuel management systems can comprise a mass air flow sensor 128 and an oxygen sensor 130. In one embodiment, mass air flow sensor 128 is connected to a micro electric device 132. In one embodiment, oxygen sensor 130 is connected to a micro electric device 132. In one embodiment, items 128-134 can be connected to an engine computer unit 136, as discussed infra.
In one embodiment, said air-to-fuel ratio can comprise a mass ratio of air and fuel present in engine 114. In one embodiment, said air-to-fuel ratio can comprise a stoichemical mixture of 14.7 to 1. In one embodiment, engine 114 can control a volume of air coming into air intake 112. The term “air” refers to the mixture of gases that surround engine 114. Generally, air can comprise 79% Nitrogen and 21% Oxygen. Traditionally, air is provided to engine 114 through air intake 112, and engine 114 burns hydrocarbon fuel within air.
In one embodiment, engine 114 can regulate said stoichemical mixture in order to balance for optimum efficiencies and performance. For example, in one embodiment, micro electric device 132 can monitor mass air flow sensor 128 to ensure a proper amount of air is provided to air intake 112 to ensure engine 114 has said stoichemical mixture. In one embodiment, said stoichemical mixture is the working point that modern management systems use to control fuel usage. For example, in one embodiment, Otto cycle engines (spark plug non diesel) can comprise said stoichemical mixture of air-to-fuel ratio is 14.7 to 1. In one embodiment, a mixture less than 14.7 to 1 comprises a “rich mixture” and a mixture greater than 14.7 to 1 comprises a “lean mixture.”
In one embodiment, adding said gases 110 into air intake system 112, greater efficiencies of combustion can be achieved by engine 114. In one embodiment, adding gases 110 (such as oxyhydrogen) to air intake 112 said stoichemical mixture can be altered. In one embodiment, adding gases 110 to air intake 112 can increase said air-to-fuel ratio and thereby create said lean mixture. When the gas mixture is added to an air intake system of an internal combustion engine, a combustion efficiency can be increased resulting in reduced usage of hydrocarbon fuel and reduced exhaust emissions of greenhouse gases.
Changing said stoichemical mixture can cause issues within many embodiments of engine 114. In many embodiments, engine 114 can comprise an engine computer unit 136 comprising a data connection with micro electric device 132 and/or micro electric sensor controller 134. In one embodiment, engine computer unit 136 can control said stoichemical mixture by monitoring mass air flow sensor 128 and/or oxygen sensor 130 and altering a volume of air coming into air intake 112. In one embodiment, oxygen sensor 130 can measure an amount of oxygen (and other chemicals) present in exhaust system 115. In one embodiment, oxygen sensor 130 can produce a signal 138 between 0.0-1.0 volts representing a range of oxygen output readings. In one embodiment, where said stoichemical mixture is optimum, oxygen sensor 130 can produce signal 138 of 500 millivolts. In one embodiment, where signal 138 falls below 500 millivolts, said stoichemical mixture can be interpreted as being said lean mixture. Likewise, in one embodiment, where signal 138 reads above 500 millivolts, said stoichemical mixture can be interpreted as being said rich mixture. In one embodiment, where oxygen sensor 130 reads as said lean mixture, engine computer unit 136 can be programed to react by increasing a fuel injection process within said engine 114 in order to said stoichemical mixture. In so doing, an increase in said fuel injection process can cause engine 114 to use more fuel (such as gasoline and/or diesel) and thereby drop in efficiency. A problem arises, therefore, where introducing gases 110 into engine 114 can causes oxygen sensor 130 to read said lean mixture.
In one embodiment, said water electrolyzer system and water electrolysis method for internal combustion engines can comprise modifying one or more signals from oxygen sensor 130 and/or mass air flow sensor 128 to indicate a balanced stoichemical mixture in exhaust system 115 when an original signal indicates a lean mixture. That is, in one embodiment, said water electrolyzer system and water electrolysis method for internal combustion engines can comprise ensuring that said engine 114 does not run inefficiently when gases 110 are added into air intake 112. Accordingly, in one embodiment, signal 138 from oxygen sensor 130 can be modified by installing an electronic fuel injection enhancer 140 between oxygen sensor 130 and engine computer unit 136. In one embodiment, electronic fuel injection enhancer 140 can comprise a digital device capable of modifying said signal 138 such that engine computer unit 136 does not alter said fuel injection process. For example, in one embodiment, electronic fuel injection enhancer 140 can reduce signal 138 from 500 millivolts to 350 millivolts. In one embodiment, reducing signal 138 can cause engine 114 to run in said lean mixture which can accommodate the introduction of gases 110 (such as oxyhydrogen) into engine 114.
In one embodiment, said nonconductive material can comprise seamless polyethylene construction. In one embodiment, water electrolyzer 100 can comprise a casing 200 and a hand hole cover 202.

In one embodiment, interior portion 212 can be accessed through aperture 210 when hand hole cover 202 is removed. In one embodiment, hand hole cover 202 can comprise a handle 214. In one embodiment, hand hole cover 202 can attach to casing 200 by a threading by screwing hand hole cover 202 into casing 200 or by tension by wedging hand hole cover 202 into casing 200.

In one embodiment, water can pass through second fitting 224, through second tubing 228, through cooling system 106, through first tubing 226 and into first fitting 222. In one embodiment, a domed liquid level sight (not illustrated) and sensor 120 can be provided for maintenance of water electrolyzer 100.
In one embodiment, an amount of hydrogen and oxygen gas produced by water electrolyzer 100 can be proportionally correlated to the capacitance of electrolyte 306. In one embodiment, electrolyte 306 can comprise a distilled water. In one embodiment, distilled water comprises a proper material selection for electrolyte 306 since distilled water can be capable of controlling an electrical current.
In one embodiment, hand hole cover 202 can be removed from water electrolyzer 100 to access electrode cells 300. In one embodiment, electrode cells 300 can be installed by removing hand hole cover 202, inserting electrode cells 300 through aperture 210 and into water electrolyzer 100, attaching electrode cells 300 to a bottom portion 310 of interior portion 212 of water electrolyzer 100.
In one embodiment, cap assembly 218 can be opened to remove or add water to reservoir of water 302, electrolyte 306, gases 110 or other materials as necessary. In one embodiment, gases 110 can travel through outlet fitting 220 and feed line 108 to air intake system 112, as discussed supra.
In one embodiment, a byproduct of the electrolysis process can comprise an excessive increase of temperature within water electrolyzer 100. In one embodiment, said water electrolyzer system and water electrolysis method for internal combustion engines can require said temperature of reservoir of water 302 to remain within a temperature control range between 42-150 degrees Fahrenheit.
