Fuel Saving Devices

Advantages of the HHO Technology

  1. Savings up to 30% in your actual fuel spendings. This is valid for both highway and town (city) driving as well. Just imagine how much you can save by the end of the year!
  2. Increases the power and performance of your vehicle. The more fuel you burn, the more the engine gets rattled up and wrecked. Once you switch to water, it enhance power, and performance.
  3. Reduces the CO2 emissions. Eliminating pollution and other harmful excretes our engines let out. What´s wrong with doing something good for the environment?
  4. Reduces the temperature in the engine. Also improves engine life-span since its burning at a much cooler state.
  5. Removes the carbon in your motor and prevent future carbon build up.
  6. Lower noise in the engine. Hydrogen effect in the combustion cycle. The engine will sound much quieter than it was before, this is due to less combustion in your car.
  7. Increases the life span of your engine.

How Does HHO Gas Work in your Car?

Inside the engine there are pistons moving rapidly up and down at a constant rate, generating the power for the car. When a piston lowers it creates a vacuum which sucks in fuel and air (Intake). When it rises it compresses the fuel (Compression) and the spark plug ignites it (Power). An engine will ideally only fire the piston when it has completely reached the top of its tube. However, most engines fire early and don't burn the fuel completely. This creates inefficiency, increases consumption and creates pollution.

When the HHO Gas mixes with your gasoline it increases the Octane rating and the amount of compression required before the Gas ignites. The piston must then compress the fuel completely before it ignites, and the extra Hydrogen allows the fuel to burn more completely reducing the amount of waste (emissions). This also adds a bit more power to the engine, which increases its efficiency and improves your km per liter.

Independent research has shown that HHO conversio\n can and does work.These studies have shown that HHO converted engines require less gas and produce less carbon emissions. Please contact us for detailed information over NASA, US Department of Transportation andUS Department\ of Energy Reports.

What research shows is that adding hydrogen will allow the engine run on a leaner fuel/air condition. Without adding hydrogen, the stoichiometric ratio of gasoline/air is 1 to 14.7 by mass. With hydrogen added, the engine can run at a gasoline/air ratio of 1 to 20 or more, which is impossible without the adding of hydrogen.

The input of HHO does not add much more energy as we understand it. However, the presence of hydrogen acts more like a rectifier or reformer – it helps the heavy fuel molecules to burn more complete than without HHO. That is, the small amount of HHO in the engine puts the otherwise unburned fuel into use which shifts the conventional fuel/air stoichiometry to a leaner condition.

Great! We will have a low cost hybrid. Converting your car is reversible and you can always put it back to normal fuel without decreasing value

And,... is this technology safe?

The process is very safe because the HHO gas is extracted on demand and burned steadily from the water, unlike larger volumes of pure hydrogen which are highly flammable. The generator produces hydrogen as your car needs it, not using storage tanks. This system doesn't modify your engine or any other part of your car. It is an accessory and complementary system that can be set up or removed in minutes without any difficulty. It only acts as an add-on to increase your fuel efficiency.

But, won't it damage my car? We frequently hear this question and the answer is No... Reason? The answer is simple:

In first place, a HHO generator doesn't modify your engine or any other part of your car. It is an accessory and complementary system that can be set or removed in minutes without any difficulty. The device allows an improvement of the working conditions in your engine. The hydrogen changes the cycle of combustion in the motor for a plane cycle with the reduction of noise and smaller vibrations in the parts (ex: cleaner pistons and valves). The system increases the power of your engine, making the acceleration easier. After the acceleration, you won't have to press the pedal a lot to maintain the speed.

Our Hydrogen Hybrid conversion guides will show you how to build and install your own Hydrogen Generator System (HHO Generator) which produces hydrogen "On-Demand", only as you need it.

1. What are the fuel savings and advantages using our Hydrogen Technology?

Most users have economies from 20 to 30% in fuel consumption. There are cases of higher results normaly in older cars or using the HEC Chip in electronic fuel injected cars. Hydrogen reduces fuel consumption by forcing the carbom based fuel to burn more completely and efficiently. Hydrogen also helps to clean carbon deposits inside the engine. Hydrogen exhaust emissions are pure water. So, you save fuel, save money and save the environment.

2. Is a hybrid fuel system more prone to rust or corrosion?

No. The fossil fuel [gas or diesel] produces enough heat during combustion to vaporize the Hydrogen as it converts back to water and exits the exhaust system.

3. Can this system improve my performance?

Yes, the injection of Hydrogen into your internal combustion engine will assist in cleaning the internal parts as the engine runs. It will increase the torque and horsepower and reduce the hydrocarbon pollutants currently being released into the air through your exhaust. Hydrogen burns faster and cleaner than gas or diesel within your engine. This makes your vehicle run smoother, longer, cooler, and more efficiently than ever before.

4. Does it work with Diesel, Petrol or GPL vehicles?

Yes, it works with all vehicles with internal combustion engines.

5. Does the hydrogen generator cause any short or long term harm to my engine?

No, the hydrogen generator does not cause any problems to the engines.

6. What type of routine maintenance is involved?

Filling the water tank with distilled water as needed. Every 1000 km you will need 1 liter of water and add litle bit of electrolyte. Every siix months, depending on amount of use, it is recommended to drain and flush the system and replace with fresh distilled water and electrolyte catalyst.

7. What is the electrolyte used?

The best electrolyte is KOH (Potassium Hydroxide). Very cheap and easy to find.

8. Will the water in the unit freeze in winter?

No, if you add about 20-25% of isopropyl alcohol to the reservoir solution to avoid freezing in winter months.

9. What if I don’t use Distilled water in my generator?

Distilled water is basically pure water. Other types of water like tap water, mineral water, pond water, sea water, etc., will work but they will also quickly cause the electrolyte to become “muddy” due to the minerals and impurities in the water. The muddy electrolyte will build up on the generator plates and act as an insulator causing Hudrogen gas production to suffer. The same is true with many other types catalyst, especially any catalyst containing sodium, like baking soda or sodium hydroxide. Sodium will quickly contaminate the electrolyzer plates and cause the unit to become ineffective.

10. Can the hydrogen generator explode?

No. The hydrogen production is made on demand. You will have hydrogen only when your car is moving. Unlike pressurized gas tanks, there is only a small amount of hydrogen pressure in the system.

11. If I have questions is there any tech support for my Hydrogen Generator?

Tech support is provided for your Hydrogen Generator (Contact form).

12. Is there any kind of warranty that comes with my Hydrogen Generator?

Yes, 2 years 100% warranty for parts and unit repair or replacement.

13. In case of an accident will the Hydrogen Generator blow up?

Absolutely not, all you will have is water and electrolyte on the ground.

14. Can we use the Hydrogen Generator on a power generator?

The Generator can be used on any power generator-

15. What is the products life?

To date we have units sold for 2 years still operating.

16. This breaks the laws of thermodynamics. It should not work!

A common fallacy is that it takes more energy to produce the HHO than the energy it releases. This is true in part when we see only the electrolysis process but when the HHO gas is mixed with your usual fuel inside the engine it allows the fuel molecules to burn better and more efficiently thus releasing much more energy than before. This is why it works.

17. Do you have a reseller distribution program?

Yes, if you are interested in becoming our reseller please contact us by e-mail to Contact form

18. Why do your kits costs less than others?

It's because we manufacture and produce all of our products. Due to the large volume of units produced we can buy materials in large quantities at the very best deal and streamline our production and pass the savings on to you. It would make no sense for us to have the best product out there if it were so expensive that the average consumer could not afford it.

19. Can I use a bigger HHO model in my car?

Yes, you can use the immediate above model for your car. The fuel savings will be not much higher but the life span of the generator will increase a lot. For the small price difference between models maybe it is a good investment.

20. What safety devices are in the kits?

We have included in the kit a bubbler and a non-return check valve to prevent any damages if the engine backfires. The bubbler will also wash any traces of electrolyte vapor out of the gas being sent into the engine.

21. Can I use any kind of water?

It is recommended that you use distilled or de-ionized water but you can use tap water if it does contain too much iron or limestone.

22. How often do I have to check the water level in the tank?

Check it about every time you fill your car with a full fuel tank.

23. Why do your kits costs less than others?

It's because we manufacture and produce all of our products. Due to the large volume of units produced we can buy materials in large quantities at the very best deal and streamline our production and pass the savings on to you. It would make no sense for us to have the best product out there if it were so expensive that the average consumer could not afford it.

24. Will installing an HHO kit void my vehicle warranty?

No. It is an add-on device that can be easily removed. Since you are not modifying the engine or computer your HHO kit does not void your warranty.

25. My car doesn’t have much space under the hood. Where can I install the HHO System?

There is always some place a unit can be installed. Our Hydrogen generator is the smallest on the market, the size of a motorcycle battery. The best place is in front of the car under the bumper.

26. How much would it cost me to have a mechanic install this?

Installation to your vehicle can be easily done by any good mechanic, or by yourself. Mechanics normally like the idea and respond well once they see the installation instructions. Installation depends very much on your vehicle and the hourly rate of your mechanic. However we can estimate your installation will take between 1,5 hours up to 3 hours.

27. When do I get my instructions manual?

You get acess to the manuals download page immediately after you make your payment. After the transaction you will get instructions to continue to the download page.

28. Does HHO injection work on vehicles with Turbo?

Yes. HHO works in turbocharged engines. Just make sure to inject the HHO gas before the turbocharger, not after.
