VG,
If this device produces hydrogen (what is level 4?) then how does it do so? I know for a fact it cannot be the heat or the pressure in the cylinder. Remember the steam in a turbine at coal, oil or nuclear power plants reaches temperatures many times higher than that of a car's cylinder, and much higher pressure too.
If the device uses electrolysis to separate hydrogen and oxygen, I don't see this info anywhere on their webpage.
Hydrogen is not easily separated from oxygen in water without the use of an electric current.
Additionally, I fail to see the benefit of introducing hydrogen into the cylinder in the first place. I understand the benefit of a fine water mist.
