WHAT IS HHO?
HHO stands for 2-parts Hydrogen & 1-part Oxygen. When 2 Hydrogen atoms are bound to 1 Oxygen atom, you have water, but when you separate the atoms from each other, you have Hydrogen & Oxygen mixed gas. The correct term for this gas is Oxyhydrogen.
There are many names for this gas mix, such as browns gas, green gas, Hydroxy, Di-Hydroxy and water gas. The wonderful thing about this gas is the byproduct, which is water. There is no smog or fumes that are plaguing our planet today.
HHO (Oxyhydrogen) will combust when brought to its autoignition temperature. For a stoichimetric mixture at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). The minimum energy required to ignite such a mixture with a spark is about 20 microjoules. At standard temperature and pressure, Oxyhydrogen can burn when it is between about 4% and 95% hydrogen by volume. When ignited, the gas mixture releases energy and converts to water vapor, which sustains the reaction: 241.8 kJ of energy (LHV) for every mole of H2 burned. The amount of heat energy released is independent of the mode of combustion, but the temperature of the flame varies. The maximum temperature of about 2800 °C is achieved with a pure stoichimetric mixture, about 700 degrees hotter than a hydrogen flame in air. When either of the gases is mixed in excess of this ratio, or when mixed with an inert gas like nitrogen, the heat must spread throughout a greater quantity of matter and the temperature will be lower.

Electrolysis involves the passage of an electric current (DC) thru electrodes. As we know, batteries have a positive and a negative.
A pure stoichimetric mixture may be obtained by water electrolysis, which uses an electric current to dissociate the water molecules:
Electrolysis: 2 H2O → 2 H2 + O2
Combustion: 2 H2 + O2 → 2 H2O (Source: Wikipedia)
With electrolysis, you have 2 types of electrodes called cathodes and anodes. The cathodes are positively charged; the anodes are negatively charged. The electrolysis process causes oxidation (rust), which can wreak havoc in an HHO generator with corrosive materials.
Water, by itself, is not a good conductor of electricity, so an electrolyte is commonly added to the water to allow electric current to pass through the water, breaking it down into HHO. There are many types of electrolytes, and each has pros and cons. Most manufactured HHO generators are designed for a particular electrolyte. We discussed what HHO is and how it's made, but how does it help?
"Modern gasoline engines have an average efficiency of about 25 to 30% when used to power an automobile. In other words, of the total heat energy of gasoline, 70 to 75% is rejected (as heat) in the exhaust or consumed by the motor (friction, air turbulence, heat through the cylinder walls or cylinder head, and work used to turn engine equipment and appliances such as water and oil pumps and electrical generator), and only about 25% of energy moves the vehicle."

Adding the HHO gas to the air intake increases efficiency. It creates an atmosphere that allows the gasoline to burn more cleanly and efficiently, and the engine requires less fuel whilst operating more smoothly and producing less carbon monoxide and dioxide.
