So you mean steam? If I remember my school chemistry correctly, mixing elemental hydrogen and oxygen only makes water and nothing else.
Elemental hydrogen and oxygen can not co exist, it always becomes water. If you mean separate Hydrogen and separate Oxygen, you would need separate tanks of both run separately across the intake but then that would be extremely flammable and highly dangerous.
If you wish to sell your product successfully then please come clean and explain things logically that can be cross-verified by anyone. Otherwise it is just a scam.
Also, its okay to accept that you use steam through the throttle to clean the internals.
P.S. Liquid Hydrogen(LH2) and liquid oxygen(LOX), stored in separate tanks, are used as propellant and oxidiser in rocket fuel by NASA.
