The procedure is 100% safe for any internal combustion engine. Only carbon deposits «burn». When burned, the gas does not affect engine parts and their coatings.
Hydrogen contributes to more efficient combustion of the fuel-air mixture. Brown's gas (HHO) or "explosive gas" is colorless and odorless, composed of two parts hydrogen gas and one part oxygen.
The regular fuel-air mixture, enriched with HHO gas, acquires new physical and chemical characteristics and, igniting on a running engine, allows burning carbon deposits in the combustion chamber and cleaning the systems associated with the combustion chamber.
Hydrogen during oxidation (combustion) not only produces a large amount of energy, but also turns into water in the form of superheated steam. Superheated steam is an effective solvent. It cleans both the combustion chamber and all elements of related systems, EGR valve, catalytic converter, particulate filter.
