Does HFTI Streaming Hydrogen Systems Fuel Combustion Supplement add to or replace the original engine fuel?
No. IHFTI Fuel Combustion Supplement produces a Hydrogen-Oxygen gas on-board, near the engine, which flows through a tube into the air intake of the engine to enhances its combustion abilities to create a cleaner burn of the fuel. This results in less fuel used and less exhaust emission as well. Only engines enabled to use of Pure Hydrogen fuel replace the fossil fuel completely.
