hho carbon cleaning is the use of catalytic properties, combustion characteristics of oxyhydrogen gas, the temperature characteristics of oxyhydrogen flame, through inside the engine intake manifold into cars, and gasoline, air mixed burning, engine internal piston top, into the exhaust valve, airway, oxygen sensor, ternary catalytic converters, inside the engine cylinder block and other assignments for nano dust, carbon deposition on the surface of the degradation with car exhaust gas discharge. After the hydrogen and oxygen molecules are burned, water vapor is produced, so there is no damage to the car, there is no harmful gas or material emissions, very environmental protection.
