How does the HHO kit work?

By using the extra power of your vehicle’s alternator, we break the bonds between the water molecules. Practically we produce gas from the water – Oxy-Hydrogen, also called HHO gas.

HHO gas is the most potent and calorific fuel in nature. When the produced HHO gas goes to the air-fuel mixture of any Internal Combustion Engine, we make the combustion of fossil fuels such as Petrol, Diesel, LPG, or CNG more complete and efficient.

As a result, you get fewer emissions and reduced fuel consumption.

Saving fuel expenses up to 35%

The average fuel saving of measured vehicles is 22%

Reducing emissions up to 78%

Reduced emisions will allow you pass any emission test and never worry about clogged DPF

Active Carbon Cleaner

HHO gas burns in total all carbon particles and keeps your engine carbon-free

Reducing engine noise

Quicker burning of the fossil fuels reduce dramatically the noise in the engine

Reducing engine wearing

Less carbon in the engine oil means less wearing, which means a longer engine lifespan
