HHO - Converting to HHO Gas Hybrid Fuel

How is HHO Gas Generated?

In a simple glass of water there is a tremendous amount of energy, if only you can properly harness it. Most people are aware that water is made up of two parts hydrogen and one part oxygen - H2O. In this form H2O is an inert substance, good for nourishing life, but not for producing energy. However, when mixed with the right catalyst, and with the right amount of energy applied to it, the H2O molecule can be rearranged in such a way that it's tremendous energy potential is unlocked.

So, what is this magical catalyst? This is the part where you will be amazed at how simple creating HHO actually is.

The catalyst is.. cue the drum roll..

household baking soda.

By simply adding the right amount of baking soda to a jar of distilled water, you are creating the right conditions to alter the molecular structure of water into a high energy gas with the addition of some electricity.

But where can you find electricity under the hood of a car? If you guessed the battery, then you would be right.

How Does HHO Power a Car?

A vehicle wastes MUCH energy in the form of both heat and excess electricity coming from the alternator to the battery. With a little very basic wiring, you can tap some of this excess electricity and route it into the hho generator ( containing a water/baking soda mixture). The end result of this procedure is the production of HHO gas.

HHO gas is packed with energy and is extremely clean burning. After combustion, the HHO gas simply turns into water. By mixing this HHO gas with your gasoline and the right amount of air, you can turn your car into a gas saving water car hybrid.

The technology used in creating an HHO gas hybrid car has existed for many years, and as you can see, HHO technology is really quite simple. It's only recently become popularized because of the rapidly rising fuel prices.

There are many HHO generator guides available with plans and instructions for building a homemeade version of the HHO gas system just described. You'll also find a growing number of prebuilt HHO generator kits that are quite affordable, especially considering the gas and money you'll save with HHO.

HHO Conversion - Necessary Components


A supplemental HHO system consists of a fuel pre-heater assembly, an electrolyzer, and an ECU (vehicle computer) compensation method/device.

When the HHO generator is used with fuel additives such as xylene and acetone, along with sensible driving habits, it can produce dramatic results in fuel economy - sometimes over 50%.

Horsepower is also drastically increased if the air/fuel ratio is not modified, because HHO gas is very combustable, much like nitrous oxide used in racing cars.

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.

Electrolyzer: This is the heart of the system and usually referred to as an HHO generator. An electrolyzer (hho generator) uses the process of electrolysis to change water into HHO gas (hydrogen and oxygen gas). The electolyzer consists of electrodes that produce HHO gas when submerged in water made conductive with electrolyte such as potassium hydroxide or simple baking soda.

When electrical current from the vehicle's battery is applied, the electolyzer, or HHO generator, produces a substantial amount of HHO gas, which makes the car's combustion process more efficient. The standard of HHO gas production is measured in liters per minute. (LPM) 1 LPM is considered baseline for a functional supplemental HHO electrolyzer.

The HHO gas output of the generator is routed to the vehicle's air intake and vacuum intake manifold. The smaller molecules of the HHO gas strike the larger pre-heated gasoline molecules, breaking down the covalent bonds even further and atomizing the gasoline, while adding a combustable catalyst.

ECU Compensation method: If an electrolyzer is used in a vehicle and nothing more is installed, little or no gains in combustion efficiency/MPG may be seen. This is because the ECU (on board computer) of the vehicle will detect more oxygen in the exhaust via the oxygen sensors. More oxygen in the exhaust usually tells the ECU 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 supplemental hydrogen system. The combustion of HHO 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 HHO. You can find a good selection of EFIE on eBay, and EFIEs can be purchased online from numerous retailers, 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 aluminum 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.

Fuel Additives: Acetone and Xylene used as gas saving fuel additives have been proven to increase fuel economy by breaking down the covalent bonds of the gasoline molecules, making them easier to atomize and ignite in the combustion process.

Emission/pollution reduction

Emissions and air pollution from your vehicle are greatly reduced while using supplemental hydrogen because more of your gasoline is being completely used up and not being burned in your catalytic converter. The biproduct of burning HHO gas is heated water vapor, which steam cleans the inside of your engine and removes damaging carbon build ups and performance robbing sludge.

Using a supplemental hydrogen system helps the environment twice by decreasing fuel dependency while also reducing pollutants.

By using a properly installed supplemental HHO system, the user and the environment will greatly benefit. All that's needed is a small amount of user intervention by refilling the water and electrolyte for the HHO generator/electrolyzer based on individual use.

If more people would employ this system we could effectively reduce dependency on foreign oil, while also preventing damage to our environment.

Why not assemble and install an HHO system of your own today? Expenses to convert to HHO are tax deductable, and you'll be saving gas AND the planet at the same time.

HHO, Fuel Injection, and EFIE

First, some Fuel Injection Basics


Fuel injected vehicles use a computer and sensing devices to sense and maintain the correct air/fuel ratio. One of the key sensing devices is the oxygen sensor.

Fuel injected vehicles have one or more oxygen sensors installed in the exhaust stream. The computer extrapolates what the air/fuel ratio is based on the amount of oxygen in the exhaust, as reported by the oxygen sensor.

When a fuel saving device is installed, such as a HHO generator, the petroleum based fuel is burned far more completely. One of the results of this is that there is more oxygen (and less unburned hydrocarbons) in the exhaust. This is a good thing, and IS Exactly what we are trying to achieve with the HHO.

However, the engine's computer will perceive this condition as a "too lean" air/fuel mixture. In other words, what is now a desirable condition in the exhaust will be interpreted as "not enough gas", and the computer will direct the fuel injectors to increase the amount of gas being pumped into the engine.

The result is that the oxygen sensor and computer prevent efficient combustion from occurring when adding a gas saving device like HHO systems!

The Solution

The oxygen sensor "tells" the computer what the oxygen content is by providing a voltage on it's signal wire - a voltage that ranges between 0 and 1 volt. A reading of 450 millivolts (.45 volts) means that the fuel/air mixture is correct. Higher values means the mix is rich (has too much gas), and lower voltages means the mix is lean.

So, by adding voltage to the sensor's output, we can compensate for the additional oxygen in the exhaust.

The Electronic Fuel Injection Enhancer (EFIE) does exactly this. An EFIE adds a floating voltage to the top of whatever the oxygen sensor is putting out. It has an adjustment that allows you to control, to within a few millivolts, the amount of this added voltage. This allows the computer to be unaware of the additional oxygen content of the exhaust, and the electrolyzer can now achieve it's full potential in fuel savings.

Most cars have oxygen sensors both before and after the catalytic converter. The ones downstream from the converter do not need to be treated. Their data is used to determine when the cat converter has gone bad, but are not used in the air/fuel calculations. EFIEs are only needed for all upstream oxygen sensors.

If you are purchasing an HHO generator or HHO kit for a fuel injected vehicle, you WILL need an EFIE to get the true gas saving benefit.

And if you need an EFIE, I suggest you check for EFIEs on eBay, and the the deluxe EFIE modules available here.

BMW Producing Hydrogen Powered Car

Though the hydrogen fuel idea has long been espoused and could be old news to a lot of us, the latest engineering and technology advances for the the latest hydrogen powered BMW automobiles is something new.

In latter 1990s, BMW was worried if hydrogen fuel would actually gain a following regardless of its plain and evident environmental advantage.

Drivers have got used to the simplicity of driving thru a gas station for refueling. That same comfort isn't available with the hydrogen vehicle.

And though hydrogen is the most commonly available component in the universe, energy firms and utility companies won't be easy to persuade to build hydrogen stations if the market is low. But BMW's dedication and commitment to educate the general public and dispell preconceived notions about hydrogen powered automobiles, for example vehicular performance and safety, has paid of. Many years after the company first brought the hydrogen powered vehicle idea to the general public, BMW reports of record sales in 2004. 2005 brought more success to the Beemmer as its H2R reaped accolades and awards establishing that it can perform at par with its gas-guzzling contemporaries.

BMW is the global leader in the development of hydrogen fueled autos with internal combustion engines," asserted Tom Purves, of BMW Group ( U.S. ). "We believe that in the output range above 140 h.p., there's still no other clean, practical alternative fuel to hydrogen. The H2R automobile is more than just an idea, or a trifling exercise." BMW is offering a production vehicle with a hydrogen combustion engine included in it's BMW seven series. The 7-series luxury sedan is outfitted with a 260 horsepower, 12-cylinder standard combustion engine which has been adapted to run on hydrogen or gasoline.
