Here is a collection of scientific background, practices, references, & standards.

These document provide extremely useful information about the viability and credibility regarding the on board electrolysis of water and their results.

 

  1. International Journal of Hydrogen Energy
    A respected, peer-reviewed journal, published a paper by Dulger & Ozcelik entitled “Fuel economy improvement by on board electrolytic hydrogen production”, in which they found that the production of hydrogen on-the-fly was able to increase fuel economy by 35-40% and reduce emissions by 40-50% in four carbureted vehicles (attached). 
    Obviously this is only possible if the engine is not making full use of the energy of the fuel it is supplied with, e.g. due to a slow burn
    Hydrogen combusts at an extremely high speed, making any fuel it is mixed with also burn faster. (See article about this speed below)

    GE Global Research's Hydrogen Electrolyzer Receives Popular Mechanics 2006 Breakthrough Award

    An excerpt of an article in which a superior hydrolizer developed by GE follows:

    Inching closer to hydrogen as an energy source

    As many of you know, one the great challenges to creating a "hydrogen economy"-- or less grandly, any energy infrastructure that uses hydrogen as a main power source-- is that on Earth, hydrogen is ubiquitous, but never alone: it's always attached to some other jealous element. So getting the cost of the electrolysis process down is a significant thing.

    Technology Review reports that GE researchers have prototyped an inexpensive electrolyzer "that they believe could lead to a commercial machine able to produce hydrogen via electrolysis for about $3 per kilogram -- a quantity roughly comparable to a gallon of gasoline -- down from today's $8 per kilogram. "I could imagine a small box that sits on-site making hydrogen for a factory," Bourgeois says. "Eventually, even filling stations may make their own hydrogen.That could make it economically practical for future fuel-cell vehicles that run on hydrogen."


    Currently, he is leading a team of engineers and scientists to develop concepts for dramatically reduced cost of hydrogen generating equipment. Prior to that, he served as a Stack Architect for GE Global Research’s solid oxide fuel cell program, successfully demonstrating an operating fuel cell stack with novel sealing and assembly methods to solve the problem of high thermal strains in the cell assembly.

    Electrolyzers are fairly simple technologies: water is mixed with potassium hydroxide electrolyte and made to flow past a stack of electrodes. Electricity causes the water molecules to split into hydrogen and oxygen gases, which bubble out of the solution.

    … The core problem in improving electrolyzers for hydrogen manufacture is not how to improve the fundamental conversion efficiency, says Richard Bourgeois, an electrolysis project leader at GE Global Research in Niskayuna, NY. "You can only make it so much more efficient; there isn't a lot you can do. So we've attacked the capital costs," he says. Rather than building an electrolyzer from "metal plates bolted together manually, with gaskets between them," Bourgeois' team built one made from "a GE plastic called Noryl that is extremely resistant to the highly alkaline potassium hydroxide." Not only are the materials cheaper, but the plastic makes the whole device easier to manufacture, which further drives down the cost.
    GE's new electrolyzer could be ready for production in a few years.

    A Promising Concept for Ultra-lean Homogeneous Combustion

    Ultra-lean-burn combustion is viewed by many as a necessary next significant step in the evolution of the gasoline engine. However, emission constraints require that these engines operate under stoichiometric conditions to avoid costly emissions control solutions. The addition of small amounts of hydrogen to the cylinder charge can allow these types of engines to operate much leaner than they otherwise could, eliminating the need to treat NOx emissions altogether. While this is not a new idea, it is Arvin-Meritor's development of a compact and fast-response fuel reformer that is bringing this concept much closer to reality.

Superhot Atomic Flame by Dr. W.A. Rhodes – 03/18/00

Superhot Atomic Oxy-Hydrogen Flame

Thanks to Dr. William A. Rhodes for sharing this.COMMON DUCT ELECTROLYTIC OXYHYDROGEN

 

Readers may wonder why I waited three decades before regaining interest to probe several unanswered questions of this system.

 

A friend on the Internet discovered the second patent number under my name and notified me that another party had patented a new version of this concept and was claiming discovery of a new gas.

Inspection of his patent showed his claim as discoverer was not valid, since my first patent predated his by eleven years. I was not about to allow him that recognition.

 

After all, I reasoned, should the second man on the moon logically claim the distinction of being the first? And so, research began resulting in this document.

 

The answers here are by no means conclusive, but lead to a better understanding of a very complicated reaction. If references are found proving priority over mine, then I will yield.

The name of the culprit was Yull Brown of Australia, now deceased who “invented” Brown’s Gas.

 

COMMON DUCT ELECTROLYTIC OXYHYDROGEN


Parameters & Variables
by Dr. William A. Rhodes, Physicist  

 

HISTORY

This concept was discovered in 1961 by request from a manufacturer for a new and novel means for producing torch flame temperatures beyond those of that era.

 

Such system was conceived and developed involving electrolytic production of mixed hydrogen and oxygen. Prior to that time, literature on the subject focused exclusively on separation of such gases and conducting them out of the electrolyzer for tank storage.

 

Using hydrogen and oxygen immediately when generated through a common duct was not found in the literature and it appeared to be a new technology.

 

The first patent (Apparatus For The Electrolytic Production of Hydrogen And Oxygen For The Safe Consumption patent # 3,262,872 issued July 26, 1966.) dealt with intermixing the gases in an electrolyzer, issuing through a common duct for instant use in a torch. 9 claims in the patent read on;  “an outlet for said generator to conduct a mixture of hydrogen and oxygen gases therefrom,”  as opposed to other electrolyzers using separate ducts for each gas.

 

The patent contains the financing party as co-inventor. His contribution was limited to an additional small alcohol booster tank, entraining the vapour for a reducing flame.

 

The patent appears to establish my precedence in the art. Starting in 1962, the Henes Mfg., Company of Phoenix sold many thousands of their trademarked ‘Water Welder’ in several sizes, presently continuing under another name.

 

Immediately after launching the Henes venture, I began research on a large electrolyzer patented in March 1967 under the title, MULTICELL OXYHYDROGEN GENERATOR (3,310,483).

 

It contained 60 iron plates, nickel plated on the oxygen generating side and iron on the hydrogen side. This patent claims use of loosely fitting grooves for holding the plates in tank 8″x8″x16″x3/4″ Plexiglas.

 

I previously discovered that current could not bypass such plates loosely fitting in grooves of proper design. The torch flame from that unit was 20 inches long, melting everything into blue-white puddles, including firebrick, ceramics and carbon (in argon atmosphere).

 

REFERENCE PROBLEMS

 

Of all elements, hydrogen and oxygen should hold no secrets.

 

Yet, in this example they do and have been troublesome. Many experts in such gases contributed important knowledge hoping such would answer our questions. Their offerings were accurate for tank gases, but these were not tank gases and three major obstacles remained.  

 

    1. flame propagation rate (burning velocity) was unusually high.
    2. Flame temperature is far greater than tank gases.
    3. Allowing the gases to mix at the moment of generation, and delivered in a common duct for immediate consumption should contain both molecular and atomic components. Until these were examined through experiment and observation, conjecture and theories were invalid.

 

FLAME PROPAGATION RATE DETERMINATION

 

SETUP: A phototransistor cell was attached to a Plexiglas base containing a groove to locate the start and finish marks on a known length of transparent plastic tubing.

 

An ignition chamber with sparkplug was attached to a 2500 v transformer controlled with a button switch. The electrolyzer was attached to the input end of the spark chamber, a 22 ft length of tubing was attached to the output side of the chamber.  

 

The first marked tubing position was placed in the phototransistor groove, and the 20 ft mark was placed on top of the first tubing mark. Recording equipment included a dual pen strip-chart recorder with parallel connection to a memo-scope and audio tape recorder.

 

NIST WWV clock ticks were coupled to all. With this setup we hoped to capture precision measurements of flame front velocity plus rise and fall time.

 

TESTS: Electrolyzer gas purged the tubing, and since the flame is in the UV, the electrolyzer was allowed to run until a trace of KOH allowed visual spectra to produce a slight pink-white. Stripchart, memoscope and recorder running and standardized. Spark initiated.

 

SIX SEQUENCES: Recorded timing for 10 feet of tubing was consist- ently 1.225 milliseconds = 10,000 ft in 1.226 seconds, or 8160 ft/sec div 1088 ft/sec (speed of sound not compensated for our 1150 ft above sea level) was mach 7.5.

 

Rise and fall pulse duration via memo-scope was .5 millisecond with a total baseline to baseline duration of .6 millisecond. With exception of the small error between sea level and 1150 ft above sea level, results of these tests appear reliable. This combination has MAXIMUM INSTABILITY. Any electrostatic discharge can trigger a very mild explosion compared with tank H2 & O2. The “ashes” from burning are of course pure water.

 

LUMPED FLAME RATE CONFIRMATION The previous rate was resolved from pip spacings. These tests were made with the plastic tubing wound into a small donut with phototransistor mounted on the focal plane of a camera lens. A flat-black background behind the donut and floodlight illumination allowed the donut image to be adjusted to cover the active area of the phototransistor. The tubing beyond the measured marks were covered to prevent errors from their exposure.

 

Instrumentation and standardization was identical to the previous test. Recorded data of the previous were pips, marking the beginning and ending of the flash. This time, burn illumination produced a slightly rounded flat area with a baseline to baseline rise and fall of .6 milliseconds as before.

 

(Previous test shots allowed strip chart recorder gain adjustment for approximately 3 cm reading. The flat tracing showed gradual rise and fall of about 2 mm from beginning to end of a sequence.)

 

Time measurements of six sequences were identical to the previous. The last test was made with the tubing exit clamped off, and gave readings identical with the others. No tubing rupture occurred and explosion sound was muffled. These should provide sufficient evidence of the flame propagation rate of such mixed gases.

 

FLAME TEMPERATURE

 

Flame tests in an argon atmosphere directed on several layers of carbon fiber fabric with its micron size filaments (Used on the stealth fighter & bomber.) melted carbon filaments into brilliant globules.

 

This means carbon’s melting temperature 3550C/6422F is exceeded, but its boiling point 4827C/8720F is not attained. Past that point no reference exists.

 

LIFTING POWER OF ELECTROLYZED MIXED GASES

 

First, be aware we are dealing with common-ducted gases, data being absent from NIST and the literature. There is also theory vs experimental evidence to contend with. From the CRC handbook: “Lifting power of 1 cu/ft hydrogen is about 0.075 lb at 760 mm pressure.”

 

SETUP: Our test volume chosen was 1 litre single duct electrolyzed gases. An igloo from a plastic pop bottle was cut to provide exactly 1000 ml volume between the flat igloo door top, and the upper dome. (1000 ml was from a standard 1000 ml flask, transferred to the pop bottle, marking the door top, and extending the igloo another 2″, where it was lathe cut and the doorway snipped out.

 

It was located inverted on the pan of our Mettler milligram balance. An L shaped tube on lab stand extended through the doorway and bent upward ending near the dome top, leaving the balance completely free of interference.

 

The gas generator was purged of air 15 minutes. The balance was tare arbitrarily adjusted for 30 grams +- 1 mg. The igloo was filled with pipe smoke; -6 mg deflection noted due to warmer air.

 

The gas tube was attached and maximum weight reduction of 0.510 grams was attained, rounded off to the nearest mg. Gas input was allowed to flow for 30 minutes for accuracy.

 

5 minutes after gas cutoff, the balance returned to the pre-gas reading caused by rapid diffusion of electrolyzed gases into atmosphere. Comparing H2 lifting power, 1 litre mixed gases multiplied to 1 cu/ft provided lifting power of 0.0311 lb. Or 41% that of H2.

 

Here we must consider single atoms of hydrogen 1 and oxygen 16 for lifting power against atmosphere (29+). Of course, if a stoichiometric mix of H2 & O2 were present, O2 alone would have a molecular weight of 32, and such gases introduced in the igloo would show a slight weight increase as the combination spilled *downward* through the doorway.

 

TESTS FOR STATIC GAS CHANGES

 

Over the years many suggested if such gases were collected and remained unused, several kinds of recombination's would spontaneously occur regardless of temperature.

 

Determining volumetric changes of stored electrolyzed gases was done with a calibrated 100 ml domed bell of 1/4″ thick Plexiglas open at the bottom and sliding inside a closely fitting Plexiglas container, with an L shaped gas entry tube extending upward under the bell.

 

The bell was held in place to prevent upward movement. 500 viscosity silicone oil was poured into the outer cylinder as air inside the bell was slowly exhausted, causing the oil to fill the bell completely, continuing to flow slowly into the plastic vacuum tubing, to eliminate all air. A cock on the metal L tube was turned off, and the plastic tube pulled from the L and cleared of oil.

 

Room temperature was adjusted for 80 F. When the temperature of the oil over the bell read 75 F, gas electrolysis began, allowing the plastic line to be purged of air, then connected to the cock which was turned on.

 

Gas filled the bell from top downward below the 100 ml mark. The cock was turned off, gas line pulled, and generator switched off. The cock was cracked to bleed gas down to the 100 ml level and turned off.

 

At the end of 6 months, room temperature again increased oil temperature to 75F. Volume change was not measureable. The gas was then allowed to fill the inverted bell on the gram balance.

 

Calculations gave the same answer as previous, comparing lifting ability as being 41% that of H2. (Plus or minus 2% error.) To prevent any light activity, the system was covered with black polyethylene.

 

ADDITIONAL CONDITIONS

 

The only purpose of KOH is to create the lowest possible resistance eg, highest electrical conductivity. Being slowly depleted by mist generated during electrolysis, specific gravity must occasionally be corrected by addition of KOH.

 

It is noted that any sharp metallic whisker in the storage atmosphere could cause an explosion, similar to the dangers of storing high percentage hydrogen peroxide, where the entire contents can burst into high pressure steam with disastrous results, just because somewhere in the interior someone forgot to round off a sharp edge.

 

On the other hand, these mixed gases were ignited repeatedly in a 4 liter container of 16 gage iron with flat ends and sparkplug. The only evidence of ignition was a sharp click, with no damage to the vessel.

 

A recent report revealed one experimenter was wounded with shrapnel from such explosion. The only way this might happen is from accumulation in an unusually thin container, or one made from an easily fractured plastic.

 

However, a duplication of the original multicell unit was constructed of 3/4″ Plexiglas with an interior volume of 8 liters. Half of this was filled with electrolyte leaving 4 liters for foam and gas accumulation, (Identical to the volume of the iron container.

 

The multicell had a 2.5″ diameter rupturable diaphragm of food grade Saran wrap. The unit was set on a stand in the open and ignited. The resultant pop splintered the case into many pieces which were all deposited within a radius of 5 feet around the stand. The diaphragm remained intact.

 

Such indicated the sonic wave front was responsible instead of pressure which would have ruptured the diaphragm.

 

These tests allowed us to design electrolyzer tanks of materials and thicknesses that could contain flashbacks. Viewing the permanent Plexiglas multicell in operation, electrolyte foam rises upward, but at maximum elevation allows sufficient gas space above.

 

Therefore no purpose is served with designs containing more gas than necessary for conduction out of the reservoir. Extrapolation of chart curves indicate a possible diesel type explosion as pressure approaches 400 psi. However, this is not conclusive. Generation of such single ducted gases appears to be an event not found in nature, unless lightening produces them.

 

FLASHBACK ARRESTERS

 

There are two types of arrester. For small units of one or two liters total tank capicity, two acquarium aerator stones are adequate. Over time they tend to clog with KOH vapor, but can be easily cleared by backflushing with 50% phosphoric acid.

 

For larger units a water filled U-tube is service free and best, since its inertia disallows flame movement through the water. An alternate to the U-tube is two tubes of different diameters.

[INCOMPLETE]

 

FLAME PROPAGATION RATES OF SEVERAL GASES

 

Flame propagation rates refer to complete combustion mixtures to fill a measured length of tubing and after ignition, combustion speed is measured against standard time pulses from WWV transmissions from the National Institute of Standards and Technology.

 

From the literature, the Butane rate is 60 ft/sec. Acetylene 330 ft/sec. Tank Hydrogen (H2) 680 ft/sec.

 

Since no literature could be found for mixed atomic gas, burning velocity was precision measured in our lab.

 

ENERGY CONVERSION LIMITATIONS

 

Be aware of this: If a current i flows for a time t and reacts with water whose electrochemical equivalent is e, mass of the gases released is: m=eit. This means present chemistry is forever restricted by this equation.

 

Direct current wave shapes, frequencies, half-waves, full-waves, nothing will allow gas delivery approaching unity. Some claim that under certain electrical manipulations, cells run cooler, or may produce more gas than before.

 

Yet, if precision measurment instruments are available, they will always show results exactly following this equation. Amperage readings made of rectified direct current by some hang-on ammeters produce enormous errors, leading the observer to believe cell efficiency has improved. This requires special attention to exhibit trustworthy data.

 

Note: Data on gas species percentages are incomplete. No reference source exists for atomic gases.

William A. Rhodes – Mixed Atomic Hydrogen and Oxygen

FOR GENERAL RELEASE TO THE INTERNET


Proof Of Discovery:
Precedence established for
Generation and Single Ducted Use of
Mixed Atomic Hydrogen and Oxygen




Was the second man on the moon entitled to the distinction of being the first?

 

The information below relates to my U.S. Patent 3,262,872 issued 26 July 1966, titled, “Apparatus For The Electrolytic Production Of Hydrogen And Oxygen And For The Safe Consumption Thereof.”

 

 Of the 10 claims allowed, 9 read variously – beginning in claim 2 through claim 10; “…outlet in said cover for hydrogen and oxygen produced in said generator,” to,” and an outlet for said generator to conduct a mixture of hydrogen and oxygen from said electrodes and said casing.”

 

 The nine claim references cited by the examiner are relevant to the fact that this was the first issued patent using a common delivery duct for both gases.

 

 The “et al” designates the financier of the project who included the outboard alcohol booster tank, Figs. 11, 12, qualifying him as co-inventor.

 

 Prior patents relating to generation of hydrogen and oxygen from water are separately collected and ducted out of the generator for delivery of H2 and O2.

Perhaps the only reason such mixed gases were not discovered and used before was fear of explosion. Exhaustive tests at my laboratory revealed they were harmless compared with tank gases.

 

NIST and the literature contained no references on such atomic mixtures. My instrumentation using the NIST WWV clock signal proved flame propagation (velocity) rate is 8160 ft/sec — mach 7.5, as compared to tank H2 and O2 being 680 ft/sec.

 

Make no mistake about it, mach 7.5 is not an attribute of burning H2 and O2. Other stoichiometrically mixed gases revealing flame propagation rates were Butane 60 ft/sec, and acetylene 330 ft/sec.

(Details of the setup for running such tests is available upon request.)

 

At this writing, maximum flame temperature is unknown. NIST again said they had no data, and research into that is proceeding. Already known is that tungsten melts instantly.

 

This confirms the temperature is significantly higher than 3,410 C. / 6,170 F. Mixed atomic gas volume vs stoichiometric tank gases will be determined.

 

One day, an article from the Internet was discovered by a friend and forwarded to me. It mentioned my second patent 3,310,483 of 21 March 1967 titled, “MULTICELL OXYHYDROGEN GENERATOR”, another single ducted mixed gas generator.

 

The text included the name of a Dr. Yull Brown of Australia, whose U.S.Patent copy was obtained from the U.S. Patent Office. His patent #4,014,777 was issued 29 March 1977, eleven years after my first patent 3,262,872 of 26 July 1966. My patent is one of the references cited in his patent. He publicly has been claiming discovery of a new gas called “BG” for Brown’s Gas.

 

Inspection of his patent revealed single ducted atomic gases, the same as mine.

 

I went ballistic. In the early days, I lost a lot through ignorance. But this? After regaining composure, I reasoned there must be a logical answer.

 

Since I generally ignored patent references cited against my many patent applications, reserving them for my patent attorney to study; on a few occasions I was guilty of such negligence which induces me to forgive Dr. Brown.

 

He might have committed the same oversight in claiming to be the discoverer of a new gas.

 

Regardless of claims to the contrary,

my patent 3,262,872 of 1966
(NOTE: IBM server only goes to 1971)
stands as the original discovery,
unless an earlier reference is found.

Hydrogen Injection

Here is a synopsis of a sampling of the research that has been done:

 

In 1974 John Houseman and D.J/Cerini of the Jet Propulsion Lab, California Institute of Technology produced a report for the Society of Automotive Engineers entitled “On-Board Hydrogen Generator for a Partial Hydrogen Injection Internal Combustion Engine”.

 

In 1974 F.W. Hoehn and M.W. Dowy of the Jet Propulsion Lab, prepared a report for the 9th Inter society Energy Conversion Engineering Conference, entitled “Feasibility Demonstration of a Road Vehicle Fueled with Hydrogen Enriched Gasoline.”

 

In the early eighties George Vosper P. Eng., ex-professor of Dynamics and Canadian inventor, designed and patented a device to transform internal combustion engines to run on hydrogen. He later affirms: “A small amount of hydrogen added to the air intake of a gasoline engine would enhance the flame velocity and thus permit the engine to operate with leaner air to gasoline mixture than otherwise possible. The result, far less pollution with more power and better mileage.”

 

In 1995, Wagner, Jamal and Wyszynski, at the Birmingham, of University Engineering, Mechanical and Manufacturing>, demonstrated the advantages of “Fractional addition of hydrogen to internal combustion engines by exhaust gas fuel reforming.” The process yielded benefits in improved combustion stability and reduced nitrogen oxides and hydrocarbon emissions.

 

Roy MacAlister, PE of the American Hydrogen Association states the “Use of mixtures of hydrogen in small quantities and conventional fuels offers significant reductions in exhaust emissions” and that “Using hydrogen as a combustion stimulant it is possible for other fuels to meet future requirements for lower exhaust emissions in California and an increasing number of additional states. Relatively small amounts of hydrogen can dramatically increase horsepower and reduce exhaust emissions.”

 

At the HYPOTHESIS Conference, University of Cassino, Italy, June 26-29, 1995, a group of scientists from the University of Birmingham, UK, presented a study about hydrogen as a fraction of the fuel. In the abstract of that study it stated: “Hydrogen, when used as a fractional additive at extreme lean engine operation, yields benefits in improved combustion stability and reduced nitrogen oxides and hydrocarbon emissions.”

 

In the Spring of 1997, at an international conference held by the University of Calgary, a team of scientists representing the Department of Energy Engineering, Zhejiang University, China, presented a mathematical model for the process of formation and restraint of toxic emissions in hydrogen-gasoline mixture fueled engines. Using the theory of chemical dynamics of combustion, the group elaborated an explanation of the mechanism of forming toxic emissions in spark ignition engines. The results of their experimental investigation conclude that because of the characteristics of hydrogen, the mixture can rapidly burn in hydrogen-gasoline mixture fueled engines, thus toxic emissions are restrained.

 

These studies and other research on hydrogen as a fuel supplement generated big efforts in trying to develop practical systems to enhance internal combustion engine performance. A few of them materialized in patented devices that didn’t’t reach the level of performance, safety or feasibility that would allow them to reach marketing stages.

 

California Environmental Engineering (CEE) has tested this technology and found reduction on all exhaust emissions. They subsequently stated: “CEE feels that the result of this test verifies that this technology is a viable source for reducing emissions and fuel consumption on large diesel engines.”

 

The American Hydrogen Association Test Lab tested this technology and proved that: “Emissions test results indicate that a decrease of toxic emissions was realized.” Again, zero emissions were observed on CO. Northern Alberta Institute of Technology. Vehicle subjected to dynamometer loading in controlled conditions showed drastic reduction of emissions and improved horsepower.

Corrections Canada tested several systems and concluded, “The hydrogen system is a valuable tool in helping Corrections Canada meet the overall Green Plan by: reducing vehicle emissions down to an acceptable level and meeting the stringent emissions standard set out by California and British Columbia; reducing the amount of fuel consumed by increased mileage.” Additionally, their analysis pointed out that this solution is the most cost effective. For their research they granted the C.S.C. Environmental Award.

 

We also conducted extensive testing in order to prove reliability and determine safety and performance of the components and the entire system. As a result of these tests, we achieved important breakthroughs as far as the designs of the components were concerned. We have since increased the hydrogen/oxygen production significantly. This has resulted in increased effectiveness on engine performance.

 

The results of these tests were able to confirm the claims made about this technology: the emissions will be reduced, the horsepower will increase and the fuel consumption will be reduced.

From researching the Internet we also found the following information

To best describe how Hydrogen Enhanced Combustion works, we are providing this excerpt from a University Technical Report, written by Mr. George Vosper, P.Eng.;

 

...a Hydrogen Generating System (HGS) for trucks or cars has been on the market for some time. Mounted on a vehicle, it feeds small amounts of hydrogen and oxygen into the engine’s air intake. Its makers claim savings in fuel, reduced noxious and greenhouse gases and increased power. The auto industry is not devoid of hoaxes and as engineers are sceptics by training, it is no surprise that a few of them say the idea won’t work. Such opinions, from engineers can’t be dismissed without explaining why I think these Hydrogen Generating Systems do work and are not just another hoax.

 

The 2nd law of thermodynamics is a likely source of those doubts. Meaning ...the law -would lead you to believe that it will certainly take more power to produce this hydrogen than can be regained by burning it in the engine. i.e. the resulting energy balance should be negative. If the aim is to create hydrogen by electrolysis to be burned as a fuel, the concept is ridiculous. On the other hand, if hydrogen, shortens the burn time of the main fuel-air mix, putting more pressure on the piston through a longer effective power stroke, and in doing so takes more work out, then this system does make sense.

 

Does it work? Independent studies, at different universities, using various fuels, have shown that flame speeds increase when small amounts of hydrogen are added to air-fuel mixes. A study by the California Institute of Technology, at its Jet Propulsion Lab Pasadena, in 1974 concluded:

The J.P.L. concept has unquestionably demonstrated that the addition of small quantities of gaseous hydrogen to the primary gasoline significantly reduces CO and NOx exhaust emissions while improving engine thermal efficiency

 

A recent study at the University of Calgary by G.A. Karim on the effect of adding hydrogen to a methane-fuelled engine says

... The addition of some hydrogen to the methane, speeds up the rates of initiation and subsequent propagation of flames over the whole combustible mixture range, including for very fast flowing mixtures. This enhancement of flame initiation and subsequent flame propagation, reduces the Ignition delay and combustion period in both spark ignition and compression ignition engines which should lead to noticeable improvements in the combustion process and performance

 

What happens inside the combustion chamber is still only a guess. In an earlier explanation I suggested that the extremely rapid flame speed of the added hydrogen oxygen interspersed through the main fuel air mix, gives the whole mix a much faster flame rate. Dr. Brant Peppley, Hydrogen Systems Group, Royal Military College, Kingston, has convinced me that insufficient hydrogen is produced to have much effect by just burning it. He feel’s that the faster burn is most likely due to the presence of nascent (atomic) hydrogen and nascent oxygen, which initiate a chain reaction. I now completely agree. Electrolysis produces “nascent” hydrogen, and oxygen, which may or may not reach the engine as nascent. It is more probable that high temperature in the combustion chamber breaks down the oxygen and hydrogen molecules into free radicals (i.e. nascent). The chain reaction initiated by those free radicals will cause a simultaneous ignition of all the primary fuel. As it all ignites at once, no flame front can exist and without it there is no pressure wave to create knock.

The results of tests at Corrections Canada’s, Bowden Alberta Institution and other independent tests reinforce the belief that combustion is significantly accelerated. They found with the HGS on, unburned hydrocarbons, CO and NO, in the exhaust were either eliminated or drastically reduced and at the same R.P.M. the engine produced more torque from less fuel.

 

Recently I took part in the highway test of a vehicle driven twice over the same 200-kilometre course, on cruise control, at the same speed, once with the system off and once with it on. A temperature sensor from an accurate pyrometer kit had been inserted directly into the exhaust manifold, to eliminate thermal distortion from the catalytic converter. On average, the exhaust manifold temperature was 65°F lower during the second trip when the Hydrogen Generating System was switched on. The fuel consumption with the unit off was 5.13253 km/li. and 7.2481 km/li. with it on, giving a mileage increase of 41.2% and a fuel savings attributable to the unit of 29.18%

 

From the forgoing, the near absence of carbon monoxide and unburnt hydrocarbons confirms a very complete and much faster burn. Cooler exhaust temperatures show that more work is taken out during the power stroke. More torque from less fuel at the same R.P.M. verifies that higher pressure from a faster burn, acting through a longer effective power stroke, produces more torque and thus more work from less fuel. The considerable reduction in nitrous oxides (NOx} was a surprise. I had assumed that the extreme temperatures from such a rapid intense burn would produce more NO.,.

 

Time plus high temperature are both essential for nitrous oxides to form. As the extreme burn temperatures are of such short duration and temperature through the remainder of the power stroke and the entire exhaust stroke, will, on average, be much cooler. With this in mind, it is not so surprising that less NOx is produced when the HGS is operating.

 

Assume a fuel-air mix is so lean as to normally take the entire power stroke (180°) to complete combustion. Educated estimates suggest the presence of nascent hydrogen and oxygen decreases the burn time of the entire mix by a factor of ten (10). If a spark advance of 4° is assumed, the burn would be complete at about 14° past top dead centre. Such a burn will be both rapid and intense. The piston would have moved less than 2% of its stroke by the end of the burn, allowing over 98% of its travel to extract work. The lower exhaust manifold temperatures observed when the Hydrogen Generating System was in use can be viewed as evidence for this occurrence.

 

Power consumed by this model of the electrolysis cell is about 100 watts. If an alternator efficiency of 60% is assumed, then 0.2233 horsepower will produce enough wattage. Even on a compact car, a unit would use less than ¼ % of its engine’s output, or about what is used by the headlights. The energy regained from burning the hydrogen in the engine is so small that virtually all of the power to the electrolyser must be considered lost. That loss should not, however, exceed V4%, so that any increase in the engine’s thermal efficiency more than ¼ %, is a real gain.

 

An engineering classmate suggested a grass fire as a useful analogy to understand combustion within an engine. The flame front of a grass fire is distinct and its speed depends in part on the closeness of the individual blades. If grass is first sprayed with a small amount of gasoline to initiate combustion, then all blades will ignite almost in unison. In much the same way, small amounts of nascent oxygen and hydrogen present in the fuel-air mix will cause a chain reaction that ignites all the primary fuel molecules simultaneously. Faster more complete burns are the keys to improving efficiency in internal combustion engines. Power gained from increased thermal efficiency, less the power to the electrolysis unit, is the measure of real gain or loss. It follows from the foregoing paragraph that even a modest gain in thermal efficiency will be greater than the power used by an electrolysis unit. The net result should therefore be positive. Thus onboard electrolysis systems supplying hydrogen and oxygen to internal combustion engines, fuelled by diesel, gasoline or propane, should substantially increase efficiencies.

 

While the auto industry searches for the perfect means of eliminating harmful emissions, consideration should be given to what these systems can do now, since the HGS considers reduction of harmful emissions even as the engine ages. Almost all unburned hydrocarbons, CO and NO,, are eliminated. Reducing hydrocarbons and CO causes a slight rise in the percentage of CO2 in the exhaust, but as less fuel is used, the actual quantity of CO2 produced is reduced by roughly the same ratio as the savings in fuel. In brief, noxious gas is almost eliminated and greenhouse gas is decreased in proportion to the reduction in fuel consumption. Nothing I have learned so far has lessened my belief that the benefits of using electrolysis units to supply hydrogen to most types of internal combustion engines are both real and considerable.

INTRODUCTION

 

The carbon equivalent of 180 million barrels of oil are burned each day to support the Earth’s growing population of 5 billion persons search for prosperity. Carbon dioxide built up in the atmosphere has reached levels that are about 30 per cent higher than at any time in the last 160 years. Environmental damage and health threats due to air pollution have reached every area of the planet. Continued dependence upon fossil fuels is detrimental to public health and is a dangerous experiment that may have no point of return for civilization, as we know it. Nine Americans die each hour due to air pollution.

 

U.S. Energy expenditures amount to about 440 billion dollars per year. About 50 percent of our energy is produced from foreign oil. U.S. military presence throughout the planet’s oil-rich areas to secure the oil-supply lines costs hundreds of billions of dollars each year. These great expenses curb investment in capital goods and our economy suffers.

 

Finding a solution to the difficult problems of energy sufficiency, environmental damage, and air pollution is imperative. The solution must provide convenience for near-term market acceptance and utilize renewable resources.

 

 

HYDROGEN AS A COMBUSTION STIMULANT

 

Hydrogen burns more rapidly than hydrocarbon fuels because it is smaller and enters combustion reactions at higher velocity, has lower activation energy, and incurs more molecular collisions than heavier molecules. These characteristics make it possible to use mixtures of hydrogen with conventional hydrocarbon fuels such as gasoline, diesel and propane to reduce emissions of unburned hydrocarbons. Transition from fossil fuels to renewable hydrogen by use of mixtures of hydrogen in small quantities with conventional fuels offers significant reductions in exhaust emissions. Using hydrogen as a combustion stimulant makes it possible for other fuels to meet future requirements for lower exhaust emissions in California and an increasing number of additional States.

 

Mixing hydrogen with hydrocarbon fuels provides combustion stimulation by increasing the rate of molecular-cracking processes in which large hydrocarbons are broken into smaller fragments. Expediting production of smaller molecular fragments is beneficial in increasing the surface-to-volume ratio and consequent exposure to oxygen for completion of the combustion process. Relatively small amount of hydrogen can dramatically increase horsepower and reduce emissions of atmospheric pollutants.
