HOW HHO and HYDROGEN ON DEMAND WORKS






Hydrogen (HHO) generators create a "hydroxy" gas.  When this gas is added to your cars fuel system it increases the combustion of the fossil fuel and more power is created, giving your car better gas mileage, increased performance and more horsepower. Not to mention the known fact that your car will produce less harmful emissions.

 
Your cars, internal combustion engine has an approximate energy efficiency of 25% or less, and 75% of the energy
created by the air/fuel mixture in your engine is wasted in a form of gases and heat that leave your exhaust and create pollution.
 
 By adding hydrogen gas to your cars air/fuel mixture you increase your engines efficiency.  This gives you better gas mileage since less gas is wasted.
The reason this works is because the added “hho” gas is much more explosive than gasoline and when mixed with other fuels makes the fuel
 explode in the combustion chamber more efficiently thus increasing the combustion process in your engine.

Using hydrogen generators will increase your gas mileage, horsepower by the increased combustion of fuel.  In
addition to saving money on gas, you will also cut down on your exhaust emissions since less fuel is being
wasted in the combustion process and is consumed, which benefits the environment.

Please take a few minutes and look over our site, check out our hydrogen on demand systems and feel free to ask any
questions.  All HHO Dry Cell kits are built with the Diy installer in mind, and provide you with the best system for the money.
We also create custom systems, based on the specifications you demand. 

Hydrogen Generator Creates Hydroxy Gas which enters your car through the air
intake.  This hho gas mixes with your fuel/air mixture, which increases combustion and
more efficient burning of the fuels. 
This provides better gas mileage as less gas is being wasted as well as increases
power and lowers emissions.

Continued from HHO 2u front page:

At ambient temperatures, the oxygen and nitrogen gases in air will not react with each other. In an internal combustion engine, combustion of a mixture of air and fuel produces combustion temperatures high enough to drive endothermic reactions between atmospheric nitrogen and oxygen in the flame, yielding various oxides of nitrogen. In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere can be quite significant.
Under idle conditions power is only required for extraneous components other than the drive train, therefore fuel consumption can be minimized. A 50% reduction in gasoline consumption at idle was reported by numerically analyzing the effect of hydrogen enriched gasoline on the performance, emissions and fuel consumption of a small spark-ignition engine.
Under most loads near stoichiometric air/fuel mixtures are still required for normal acceleration, although under idle conditions, reduced loads and moderate acceleration hydrogen addition in combination with lean burn engine conditions can guarantee a regular running of the engine with many advantages in terms of emissions levels and fuel consumption.
Increases in engine efficiency are more dominant than the energy loss incurred in generating hydrogen. This is specifically with regard to use of a hydrogen reformer. Overall computational analysis has marked the possibility of operating with high air overabundance (lean or ultra-lean mixtures) without a substantial performance decrease but with great advantages on pollution emissions and fuel consumption.
Overall comparing the properties of hydrogen and gasoline, it is possible to underline the possibilities, for hydrogen fueled engines of operating with very lean (or ultra-lean) mixtures, obtaining interesting fuel economy and emissions reductions. The concept of hydrogen enriched gasoline as a fuel for internal combustion engines has a greater interest than pure hydrogen powered engines because it involves fewer modifications to the engines and their fueling systems.

Research
A simplified single-step combustion reaction is represented as:
[FUEL] + [HYDROGEN] + [AIR] ? HC + CO + CO2 + H2O + NOx
1975
Research in 1975 examined hydrogen enhanced gasoline in lean combustion. John Houseman and D.J Cerini of the Jet Propulsion Laboratory produced a report for the Society of Automotive Engineers titled "On-Board Hydrogen Generator for a Partial Hydrogen Injection Internal Combustion Engine", and F.W. Hoehn and M.W. Dowy, also of the Jet Propulsion Lab, prepared a report for the 9th Intersociety Energy Conversion Engineering Conference, titled "Feasibility Demonstration of a Road Vehicle Fueled with Hydrogen Enriched Gasoline.

1977
NASA conducted research using hydrogen as a supplemental fuel to gasoline on a 1969 production engine. Their research specifically demonstrated that the higher flame speed of hydrogen was responsible for being able to extend the efficient lean operating range of a gasoline engine. They successfully used a methanol steam reformer for in situ production of carbon monoxide and hydrogen.
Lean-mixture-ratio combustion in internal-combustion engines has the potential of producing low emissions and higher thermal efficiency for several reasons. First, excess oxygen in the charge further oxidizes unburned hydrocarbons and carbon monoxide. Second, excess oxygen lowers the peak combustion temperatures, which inhibits the formation of oxides of nitrogen. Third, the lower combustion temperatures in­crease the mixture specific heat ratio by decreasing the net dissociation losses. Fourth, as the specific heat ratio increases, the cycle thermal efficiency also increases, which gives the potential for better fuel economy. Download This HHO Report
2002
Research done in 2002 shows that the "addition of hydrogen to natural gas increases the burn rate and extends the lean burn-limit". Also concluded was that "hydrogen addition lowers HC emissions", and with properly "retarded ignition timing" also reduces NOx emissions.
Further research in 2002 achieved results showing "a reduction of NOx and CO2 emissions", by modeling an on-board hydrogen reformer and "varying the efficiency". The research was specifically a "numerical investigation" done to "foresee performances, exhaust emissions, and fuel consumption of a small, multi valve, spark ignition engine fueled by hydrogen enriched gasoline".

We have positive proof that our hho generators have done exactly what this report claims on vehicles in Netherlands.
Our Netherlands hho dry cell  experiments with GNC are proving very good results - see hho testimonials
2003
In 2003 Tsolakis et al. of the University of Birmingham showed that "partial replacement of the hydrocarbon fuel by hydrogen combined with EGR resulted in simultaneous reductions of smoke and nitrogen oxides emissions (NOx) without significant changes to engine efficiency".  Similar results have been presented by a team of scientists from Zhejiang University, China, which found that "a little amount of hydrogen supplemented to the gasoline-air mixture can extend the flammability of the mixture... improving the economy and emissions of engines".
2004
Test results in 2004 show "that the H2-rich re formate gas was an excellent NOx reduct ant, and can out perform raw Diesel fuel as a reductant in a wide range of operating conditions". This is referring to Diesel fuel being used in excess, as a reductant, to cool the combustion reaction, which indeed has a mitigating effect on NOx production.
In 2004 research was conducted concluding that an "SI engine system fueled by gasoline and hydrogen rich reformate gas have been demonstrated" to achieve a "dramatic reduction of pollution emissions". This was achieved by "extending EGR operation" in addition to consuming "gasoline and hydrogen rich reformate". Emissions results show that "HC-emissions as well as NOx-emissions could be reduced to near zero". Overall a 3.5% reduction in CO2 emissions was achieved during the "FTP test cycle" The research also concluded that the exhaust after treatment system can be simplified, "resulting in cost reduction for the catalysts".

To date, Hydrogen fuel enhancement products have not been specifically addressed by the United States Environmental Protection Agency. No research devices or commercial products have reports available as per the "Motor Vehicle Aftermarket Retrofit Device Evaluation Program."

How Does A Hydrogen on Demand System Work?

 A supplemental hydroxy system, otherwise known as a Hydrogen on Demand system consists of a fuel pre-heater assembly,(optional ) a HHO electrolyzer, otherwise known as HHO Generator and an ECU (vehicle computer) compensation method. When the system is used with fuel additives such as xylene and acetone, along with positive driving habits, it can produce dramatic results in fuel economy, and absolutely huge drops in harmful emissions. Horsepower is also drastically increased if the air/fuel ratio is not modified, because hho gas is very combustible, much like nitrous oxide used in racing cars. Even without any extra fuel additives these hydrogen on demand systems will increase the miles you are able to travel per gallon of gasoline or diesel.
 
Fuel Pre-heater: A fuel preheater is a simple device, usually assembled of a heat conducting metal such as brass, copper, nickel or aluminum.  It is placed on the radiator hose of the vehicle and wrapped in a thermal blanket.  It uses otherwise wasted heat to preheat the gasoline before it reaches the fuel injection manifold or carburetor. This helps expand the dense gasoline molecules, making them closer to full vaporization temperature by the time the fuel reaches the combustion chamber and makes it easier to mix with the HHO gas from your hho generator.
 
Electrolyzer: This is the heart of the system. Commonly called a HHO generator. Most people are using HHO Dry Cells for their hho generators as they have proved to be much more efficient at producing the desired amount of hho gas. An hho generator uses the process of electrolysis to change water into hydroxy gas. (Oxyhydrogen gas) It consists of electrodes that produce hho gas when submerged in water made conductive with electrolyte, such as potassium hydroxide (koh). Electrical current from the vehicle’s battery is then applied. A substantial amount of hydroxy gas must be produced by a Hydrogen on Demand system to make the combustion process more efficient. The standard of gas production is measured in liters per minute. (LPM) 1 LPM is considered baseline for a functional supplemental hydrogen electrolyzer. The hydroxy gas output of the electrolyzer is routed to the vehicle’s air intake and vacuum intake manifold. The smaller molecules of the hydroxy gas strike the larger pre-heated gasoline molecules, breaking down the covalent bonds even further and atomizing the gasoline, while adding a combustible catalyst.
 
 
ECU Chip Compensation method : If a Hydrogen on Demand System  is used in a vehicle that is 1996 and newer and nothing more is installed, sometimes little or no gains in combustion efficiency/MPG will be seen. This is because the ECU (computer) of the vehicle will detect more oxygen in the exhaust via the oxygen sensors. More oxygen in the exhaust usually tells the ECU on your vehicle the fuel mixture is running lean, with too much air being mixed into it via the air intake. It then compensates by adding more gasoline to the mixture, and reducing the air induction, which defeats the gains of the hydrogen on demand system. The combustion of hydroxy gas produces a large increase in oxygen in the exhaust, therefore to see gains you must compensate for this. Compensation methods currently being employed are:
 
1. E.F.I.E. (electronic fuel injection enhancer): This device manipulates the voltages relayed to the ECU via the oxygen sensors. By telling the ECU the fuel mixture is rich, it will tell the fuel injectors to inject less gasoline and use more hydroxy. It can be purchased online HERE, or you can build your own.
 
2.MAP/MAF sensor enhancer: this device manipulates the voltages being sent to the ECU from the MAP or MAF sensor, effectively controlling the air/fuel ratio.
 
3.Oxygen sensor offset sleeves/wrapping in foil. These 2 methods of O2 sensor tweaking effectively reduce some of the sensor’s ability to detect oxygen, effectively leaning the air/fuel ratio.
 
How Much HHO Should I Use?

I frequently get asked about how much HHO will yield the best mileage gains for a particular car or truck. I would like to be able to give a good quantitative answer to that, but for now, I just can't. I don't have enough statistical data for different cars and trucks that have added a hydrogen on demand system to be able to do that for you. But I can tell you some information that will help you finding the optimum amount of HHO gas to use for your engine.

People new to this subject think that if some HHO is good, more is always going to be better. Others believe that the electricity used to make the HHO is actually "free energy" since the engine is turning anyway. Both of these statements are false, as I will describe below.

First lets look at the alternator. When the engine is running it transfers rotational energy, via a belt to the alternator, which then generates electricity. This energy is actually a measurable drag on the rotational energy of the engine, and it costs fuel to counter this drag. Even if you're coasting down hill, the distance you will coast will be less before you have to add gas again to maintain your speed. The bottom line? The electrical energy from your alternator costs you gas to create.

Now lets look at the gas. HHO, when burned, does not give back as much energy as the energy that was used to create it. There are several energy conversions involved. Since there is no such thing as 100% efficiency, energy is lost at each conversion. The conversions are: mechanical to electrical (alternator), electrical to chemical (electrolyser), and chemical to mechanical (burning the HHO). By the time all 3 of these conversions have taken place, when the HHO burns you'll get back about 20-25% of the energy used to create it. But don't despair just yet. Awesome gains in mpg are still achievable using this Hydrogen on Demand technology.

Where we get our gains is the fact that the HHO catalyzes the gas and causes it to burn more efficiently. We pour the majority of our gas out the exhaust pipe. The HHO causes some of this waste to be used in the combustion process. It's actually a small percentage of the waste that we're getting back too. It's just that there's so much waste, that even a small percentage recovered makes a huge change in our mileage when you add a Hydrogen on demand system. This is what makes HHO so valuable in our engines.

However, only so much HHO will give us more efficiency in this way. If you add more HHO after that, you'll then start to lose mileage because of the efficiency losses described above. I wish I knew how to tell you the exact number of liters/min is the correct amount for your car, but I can't. The only way I know of to find the exact amount that is correct is by adding a Hydrogen on demand system and then good old trial and error. As you add more HHO gas, at some point you'll hit a peak, and then your mileage will start to decline. The correct amount is the amount you were using at your peak mileage.

If you added a Hydrogen on Demand system to your auto or truck and actually go through this process, of figuring out the correct amount of hho gas for your car, please post your findings by going to our Contact Page. We would like to get some good quantitative data on amounts of HHO for various engine sizes and types, so that we can get a better idea of the amount of gas that is best for guys starting out. Please post car make/model/year, and also the electrolyser manufacturer, or if homemade, the plans used, and the specifics of electrolyte used, amp draw etc. The volume of gas produced per minute would be great.

I hope this hydrogen on demand article helped you in your quest to get the best mileage from your vehicle. If you have more questions on this subject, please contact us and we will get back to you as fast as we can.
