HHO is known as oxyhydrogen, that’s the chemical name for it.  HHO gas is formed by the water electrolysis process and it is believed to increase the efficiency of the car.  The car will not run solely on HHO gas, what happens becomes a hybrid of HHO and petroleum based fuel and this provides the energy to run the car.  With the addition of HHO, the increased efficiency of the car can be from 30 to 60 percent.

Chemically HHO is a combination of hydrogen and oxygen, in the atomic ratio of two is to one. When a substance is heated to its autoignition temperature, the combustion process occurs, causing a substance to burn and produce heat energy.   The autoignition temperature for HHO, is 1065 F and the minimum energy needed for the ignition to happen with an external source is 20 Micro joules. Once ignited, HHO converts into water vapors and releases energy, which automatically sustains the reaction.

One of the most common uses of HHO is in torches for the processing of refractory materials. Limelights which are used in the heating of lime are one of the many forms of HHO lamps are available. Becaues HHO is known to  have an explosive nature, limelight lamps have mainly been replaced by electric lighting.

With the rising cost of gas for our cars, a recent application of HHO is in running the cars on water hence the term water for gas. This is also called Brown gas.

The electrolysis of water starts as a result of the water is usually stored under the hood of the car being ignited by the spark from the battery of the car.  This then converts it into HHO or Brown gas

This Brown gas mixed with the gasoline gives the better performance of the car in relation to MPG
