What is HHO?


HHO gas, also known as oxyhydrogen can greatly increase the fuel efficiency of cars in which it is used. HHO gas is created through a simple process of electrolysis - your vehicle does not run just on HHO but rather a hybrid of gasoline and HHO which powers the car. HHO has been shown to increase fuel efficiency by as much as 60% in some cases.

HHO is a hydrogen/oxygen compound, in a two to one ratio. This is of course the same proportion as found in water. Combustion is a process in which something is burned in order to release heat energy and begins when a substance is heated to its autoignition threshold.


This is the temperature at which a given substance will spontaneously ignite with no external source of flame needed. The autoignition temperature of HHO is 1065 degrees Fahrenheit and the amount of energy which would be required for this to happen is 20 microjoules. After being ingnited, HHO is converted to water vapor and also releases energy, which sustains this reaction.

More recently, HHO has been pressed into service helping cars to run on water.  When talking about the automotive applications of HHO it is often called Brown gas. Water will be stored under the hood of the vehicle and ignited by a spark form the car battery. The electrolysis of the water stored in the car will then begin and HHO or Brown gas will be produced as a result. The air intake valve of the car's engine will pull this gas into the combustion chamber. When mixed with gasoline, this Brown gas gives vehicles dramatically better gas mileage.

It is a simple matter to install your own HHO kit for your vehicle - this does not require any specialized knowledge; you don't need to know the first thing about cars to be successful in installing our complete HHO generator kit!
