Hydrogen engine cleaning using the Hydroxy system is an innovative method for removing carbon buildup and deposits from internal engine components without disassembly. During the procedure, a gas mixture of hydrogen and oxygen is fed into the intake system, which gently cleans the combustion chambers, valves, pistons, and exhaust system during combustion.

This cleaning method allows for the restoration of fuel combustion efficiency and reduces smoke, noise, and engine vibrations. The procedure is safe for vehicle components and is recommended as preventative maintenance to maintain environmental and performance standards.
