It’s very simple. You don’t change your engine or ECU (car computer). A quart-size (95o cc) container, usually made of glass but can also be plastic or metal, is placed somewhere under the hood. You fill it with distilled water and cheap household electrolyte (causes electrical current). The device gets vacuum and 12 volts from the engine, and produces water gas as shown in the video inside.

The electrical connection is very basic - we have eliminated the need to use relays or any other complications. The device connects to the 12 volts of your battery via the ignition switch, to prevent hydrogen production when the engine is off. The device is fuse protected and draws very little current, only 1-3 amps! This could take 10 minutes or less to connect.
