Hydrogen-Enhanced Combustion Engine Could Improve Gasoline Fuel Economy by 20% to 30%

Work being done by ArvinMeritor, IAV (Ingenieursgesellshaft für Auto und Verkehr) and MIT on enhancing gasoline combustion with a small hydrogen gas stream is pointing toward a potential estimated improvement in gasoline fuel economy of 20% to 30%, depending upon the baseline engine. - Read More

Combustion lean limits fundamentals and their application to a SI hydrogen-enhanced engine concept

Operating an engine with excess air, under lean conditions, has significant benefits in terms of increased engine efficiency and reduced emissions. However, under high dilution levels, a lean limit is reached where combustion becomes unstable, significantly deteriorating drivability and engine efficiency, thus limiting the full potential of lean combustion. Due to hydrogen's high laminar flame speed, adding a hydrogen-rich mixture with gasoline into the engine helps stabilize combustion, extending the lean limit. This work studies the fundamental behavior of lean combustion in a spark ignition (SI) engine, identifying the processes that determine the engine's efficiency curve, and studying practical solutions to extend the peak efficiency and the lean limit. Lean and hydrogen-enhanced combustion data in a SI engine were generated covering a wide range of operating conditions including different compression ratios, loads, types of dilution, types and levels of hydrogen enhancement, and levels of turbulence. Combustion simulations were then performed to quantify the components that determine the efficiency vs. dilution curve. Results showed how burn duration is the primary driver of lean combustion, with a limiting 10-90% burn duration at peak efficiency and a limiting 0-10% burn duration at the onset of rapid combustion variability. - Read more

Hydrogen-Enhanced Gasoline Stratified Combustion in SI-DI Engines

Experimentalinvestigations were carried out to assess the use of hydrogen in a gasoline direct injection (GDI) engine. Injection of small amounts of hydrogen (up to 27% on energy basis) in the intake port creates a reactive homogeneous background for the direct injection of gasoline in the cylinder. In this way, it is possible to operate the engine with high exhaust gas recirculation (EGR) rates and, in certain conditions, to delay the ignition timing as compared to standard GDI operation, in order to reduce NO and HC emissions to very low levels and possibly soot emissions. The results confirmed that high EGR rates can be achieved and NOx and HC emissions reduced, showed significant advantage in terms of combustion efficiency and gave unexpected results relative to the delaying of ignition, which only partly confirmed the expected behavior. A realistic application would make use of hydrogen-containing reformer gas produced on board the vehicle, but safety restrictions did not allow using carbon monoxide in the test facility. Thus, pure hydrogen was used for a best-case investigation. The expected difference in the use of the two gases is briefly discussed.  - Read more

Predicting the Behavior of a Hydrogen-Enhanced Lean-Burn SI Engine Concept

This paper explores the modeling of a lean boosted engine concept. Modeling provides a useful tool for investigating different parameters and comparing resultant emissions and fuel economy performance. An existing architectural concept has been tailored to a boosted hydrogen-enhanced lean-burn SI engine. The simulation consists of a set of Matlab models, part physical and part empirical, which has been developed to simulate a working engine. The model was calibrated with production engine data and experimental data taken at MIT. Combustion and emissions data come from a single cylinder research engine and include changes in air/fuel ratio, load and speed, and different fractions of the gasoline fuel reformed to H2 and CO. The outputs of the model are brake specific NOx emissions and brake specific fuel consumption maps along with cumulative NOx emissions and fuel economy for urban and highway drive cycles. Model results closely match production engine performance data for naturally aspirated stoichiometric operation. Simulation of lean boosted operation with 20% gasoline reformate fraction and 20% downsized displacement predicts a 23% improvement in fuel economy. Furthermore, part load engine-out NOx emissions are reduced by 83% compared to a baseline naturally aspirated stoichiometric production engine with 10% EGR dilution.

Hydrogen-Enhanced Combustion - 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. - Read more

IEP - Advanced NOx Emissions Control
Control Technology - O₂ Enhanced Combustion

Oxygen-fired combustion has been utilized in industrial furnaces to improve energy efficiency and reduce emissions. NOx emissions reductions of as much as 80-90% have been demonstrated at commercial glass melting furnaces that have been converted to oxy-fuel firing. One of the required keys to successfully implementing oxygen-fired or enhanced combustion is an economical source of oxygen, which also can benefit numerous other technologies. Praxair is developing a novel oxygen separation technology at its Tonawanda, New York facility, using an Oxygen Transport Membrane (OTM). Ceramic membranes are attractive since they can have virtually infinite selectivity for oxygen, thereby allowing only the oxygen to pass through. There are two basic types of ceramic membranes, pressure and electrically driven. This project will use pressure as the driving force for separation.

HIGH COMPRESSION RATIO, HYDROGEN ENHANCED GASOLINE ENGINE SYSTEM

High Compression Ratio, Hydrogen Enhanced Gasoline Engine System Background of the Invention This invention relates to an engine system and more particularly to a gasoline engine system employing hydrogen enhanced operation.

Hydrogen addition can be used to reduce pollution (especially NOx) from vehicles with spark ignition engines using gasoline and other fuels. Hydrogen can be produced by onboard conversion of a fraction of gasoline or other primary fuel into hydrogen rich gas (H2 + CO) by partial oxidation in compact onboard devices suitable for vehicle applications. - Read more

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 (carbon).

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; and 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. 

Hi Alex,

Just thought I'd write & give you the latest. I just checked my gas mileage & -- to my shock -- it came out to 30.5 MPG! The last time I checked my mileage, it was only 8.3 MPG, but I had only driven it a few miles (I was too eager!) & so that's probably the actual gas mileage I was getting before you put the electrolyzer on. Man o man, was I surprised. I had driven over 200 miles since the last fill-up, so, based on the earlier gas mileage, I thought it would take at least $100 to fill the tank &, believe you me, the clerk looked at me kind of strange when I went back inside for change after putting only about $29.00 worth in my tank!

D.D.D

Dear Alex

The last tweaking you did on my hydrogen augmentation system did wonders for the mileage.  Also I got another great surprise when I first took off following your service.  The change was totally amazing.  The power when I first took off was like someone had installed a jet assist to the old van.  Just to get a feel for what had been accomplished, I took a ten mile trip down the freeway. I was watching my mile per gallon sensor and for the first five miles at 65 miles per hour, I witnessed mileage variations from 24 mpg to 57 mpg. On the way back, I had some upgrades but never got below the 24 mpg level. If you recall, my Dodge Grand Caravan had averaged 15.5 mpg for the past several years.  If I never get beyond the 24 mpg range. I will have achieved an improvement of 54%.  Also I am still fighting the system computer that keeps thinking I am running too lean.  Have to stop that interference.  We can talk about it later. I can't wait to see what difference we can make by fooling the computer.  With the advances already witnessed, I may even have the old tub tuned and get another few miles per gallon out of her. 

To put it mildly, the system works great.  Tell the world about your marvelous technology. I am already spreading the word too.

W. M.

Alex, as stated I was on average city driving 275 miles per 15 gallons of gas, my car has a 15 gallon tank, after installing of the hydrogen system in my car and placing only 11 gallons gas I received city driving 32 miles more or 307 miles.

The first thing I noticed was just how much smoother and more power I had with my engine.

I tested the gas mileage and I went from 14.7 miles per gallon to 24.8.  But the computer cut it down to 18.7 miles per gallon and that’s what I’ve been getting ever since.

This is still a great increase in power for me and a big savings in money each week in gasoline costs.

Thanks Alex!

Hi Alex,

Thank you very much for everything

I had a GREAT day!!! Vacation mode

Thanks for answering all my questions And for all your great work

I watched and left feeling very confident. I look forward to seeing you again in a couple of weeks to check it. Thanks for the pictures!! You took GREAT pictures

What I like best is that my motor does not even look dusty

Thanks again! See you soon! Keep up the great work

Hi Alex,

I have only gassed up twice so far since you installed the device on my Celica Monday 7/28. With running the A/C both am & pm, and flooring it a lot to pass on the freeway AND going fast most of the time, I am still getting about 24mpg -which I'd normally only get with freeway driving. I would normally get barely 20mpg under my current driving conditions.

What tweaks do you have and how much are they?

I will stop by soon one evening after work and maybe buy a tweak... I'll call to make an app't to see if you are around.

I have a guy with a Ford truck a 150 or 350? What are your mileage increases with those vehicles?

He wants to buy one and have you install it. I told him to wait till I see my mileage, but a truck is different and maybe those get better mileage increases than my Celica?

He will be my first sale as an affiliate and I have a lot of other people interested and waiting for me to report on my mileage.

See you soon!

It took 11.9 gallons to come up from San Diego and 6.8 to come down. Loving it, let's speed the test up. We can put on 4 & 6 packs next week and not hook up 6 for 3 days.  Will you make the hanging brackets for Monday or Tuesday? And yes I was getting calls before I got home. They where waiting in the driveway. Alex great job. See you in 4 days. Talk to you later.

Thank you.

Well, the other day you signed up and just like you...

I was looking for a way to decrease my gas expenses and I know it's no easy task. Let me briefly share my story where I started in this process.
About 2 years ago I was tired of spending a ton of money on gas for the truck I was driving. So decided to buy a small gas economic car. Right away I almost doubled my MPG. Finally, I was smiling while at the gas station as I watched the digital cash cow roll up on the gas pump.

But, after time went by I realized how much I missed driving my truck, especially during the winter and became a little tired of driving a small car around. Thought this car could also be used as our 2nd family car, not the case we quickly found out. So, the question became how do I drive the vehicle I want, while meeting my families needs and still reduce gas expenses? My wife called me crazy at first, and to be honest I was slightly skeptical about using water for gas. I made the decision to personally put together the system and tried it out on my older car... Amazingly enough within the first week I had a 82% increase in MPG.

Instantly we became believers and was so excited about this discovery that I decided to find a way to help other people Save on Gas expenses too.

To Your Gas Savings!

Right then, I've got a 1969 Landrover Series 2a 2.25L Diesel. I put magnets on the fuel line and increased the mileage on a set 17 mile route at a steady 40mph to 27.87mpg. I then constructed the single cell system and fitted it. My first run was with the bubbler closed and on the set run increased my mileage to 28.84mpg. A positive start, but I felt that the engine was being starved of HHO. I then reduced the length of the two feed pipes going to the closest point on the air intake manifold to 4 feet each from five feet and opened up the bubbler to allow a moderate amount of air through. I then ran the same run (each run took 35 minutes) and compared the results. My 39 year old Landrover did 71.43mpg!!!!

In truth, I was hoping to achieve a modest 40mpg but this is unbelievable!!

Many thanks for all your technical help. Your the first people that haven't scoffed at me for attempting to run on HHO and I greatly appreciate your support.

Regards.

I have connected a three bottle system to my 1985 ISUZU P'up and am happy with the results. I am only on the early phases of this experiment but the power is improved, and the exhaust is definitely cleaner. ... Installation is very simple. Bottle to air cleaner.

My first mileage results were really amazing I got 37% better mileage , in my 1985 Toyota P.U. truck it has a 22re fuel injected motor with 328000 miles Yes I have been driving this forever .
My mileage in the summer is around 26 to 29 mpg , in the winter its around 23 to 24 mpg depending on how cold it is , the average is 25 mpg , with the unit installed I got 34 mpg amazing , this was not highway driving back roads with hills stop and go and warm up in the morning when it cold! Also I noticed better power up hills in fifth gear.

PS I am sure to tell a lot of my friends about your unit !

Hello,

I have completed the installation today. After I completed the installation and ran the car, within minutes I could smell a BIG difference in the exhaust emission, it quietened the engine and it ran so sweetly and that was within minutes!!!!

I will be starting tests tomorrow and can't wait to prove what I already know.

This is going to be big!!!!! I will be inviting people to a demonstration shortly and will very guardedly talk to our local media because petrol prices are really hurting people here and of course the greenhouse gas issue. I want people to know about this and want to help them save on fuel etc.

Everything I have read on your website and related links appears to be so completely true which has built my faith in this development and as I have followed things out that turned out to be chasing shadows it has made me so enthusiastic about this product I am nearly bursting out of my skin.

I will stay in touch. For the record my car is a 1986 Nissan Skyline 6 cylinder 3litre fuel injected. It has only done 98,000 Klms or nearly 60,000 miles so is in very good condition.

Believe me, I would not know what I now know had I not bought my membership. Thank you for that.

A friend of mine installed one on an old Cadillac. His catalytic converter had gone bad so he removed it and took it in for emissions testing. After the test the mechanic came out and said "Boy you sure have a great catalytic converter on that car!"

My car is an 1986 Subaru GL. I bought her originally in 1989.

Two weeks ago I agreed to have the gas saving device put on my car. Immediately I noticed that the engine was much, much quieter and smoother. We did a test drive on the car with and without the device. The results were spectacular. The Subaru does 32.8 miles to the gallon. With the device - which is only the very basic fitting - the Subaru did 36.8 miles to the gallon, a saving of twelve and a half percent. With the rest of the equipment that Ozzie has now I estimate I would save circa 40%.

What was really noticeable on this test drive was the difference in the quietness of the engine and how the car picked up much more easy with the device installed. Since then, I have noticed that the car continues to improve and I feel she is back to where she was in 1989. Feels like a new car!!

I am very pleased to have this device on my car which will not only save on the gas, but clean the engine, reduce emissions into the environment, and therefore give my car a longer life, as I love my Subi.. Also this will help because this year I have to have a complete smog test to go with my application for my registration renewal. 

J.H. ( California , USA )

Thanks...I got everything...Works good on smaller motors ...I put it on a Honda civic...does about 15 % better on gas ..not bad..no tweeks...no 02 just the generator. The past few days I have made 6 more models suitable for 1.2L - 3.0L on up to 5.2L to 7.0L gas and diesel engines now working on 8+.....I have been seeing up to 45 % better gas mileage within a few weeks.

A friend installed this gizmo in my truck two months ago. After 30 seconds first start I noticed that the engine become soooo quiet. At first I thought the RPM went down because of the water, but no, the device has definitely changed the way my engine works - it does not ping anymore!

Another thing I noticed right away was that the absolutely terrible stink previously coming out of my exhaust has gone down dramatically. Man it was choking me -I can breath again!

Drove it home, engine roars +feels like much bigger engine! After 5-6 miles I kind of went into a "smooth bubble", like the engine suddenly become smooth as butter. Was a very hot day so I figured it might be the weather. I was wrong!! The car continued to run smooth in ANY weather, and kept improving all the time day after day, week after week.

It's now so quiet that FOR THE FIRST TIME now I can listen to the radio at low volume or talk on the cell phone without shouting!

On road tests I got "only" +13% improvement on MPG, but the company gave me a solution to improve that to at least 25% with small modification.

When the truck broke down I automatically blamed the new gizmo. Wrong again! It was a leaking radiator which I fixed for $1.99 using Aluma-Seal. Now I know THE GIZMO ONLY IMPROVES MY CAR all this time. And with so much less engine vibration and no valve/piston knocking, I expect the life of my engine to double!

What I DON'T LIKE now is when I open the truck window and all these OTHER cars are so noisy and stinking!!! Everybody should have this technology! I'm tired of this...well its like second hand smoking... you can call it second hand smogging LOL

E.S. (California, USA)

Ever since you installed the device, my engine has been running much more smoothly and efficiently. I drive a Jag XJ6 and my average miles per gallon has been 16-18 miles. Now that the device is installed I am experiencing 19-24 miles per gallon fuller at least. This is a substantial fuel savings for me. In addition I have more "pep" on my accelerations. It feels like I have a totally different car with more power and smoothness. Thanks for your product. I am totally impressed and satisfied. 

A.C. ( California , USA )

MY unit I have on my car is working. So far I have noticed a jump in mpg from 24ish mpg to 30ish mpg I am running it on a 2005 Nissan Sentra. I also wrapped several layers of tinfoil around my Oxygen sensor, doing this will trick your O sensor into thinking it is to hot which will affect how much gas/oxygen mixture your injectors or carburetor will take.
