A small briggs and stratton running on hydrogen and oxygen from an ondemand electrolysis unit. The video was done on a phone (Quality Poor)... The engine is started on petrol, the petrol immediately switched off... it takes over 1 minute for the petrol to run out and the pure gas (HHO) from water takes over... Mmmm, super smooth, quiet, no fumes... Just got to make more gas to run the car!


Leave the carb as it is....

Take the air filter off and fit a face plate to attach your new inputs on...

You want in air in tap for running on petrol and a gas in tap for the HHO

The HHO needs a really small tube to carry it as close to the intake inside the engine as u possibly can to keep a pressure as it enters the manifold...

And thats it! ;)

Start her on fuel and count how long it takes for the engine to rev lean as it runs out of fuel...Our little Briggs motor took approx 27 seconds to run out of fuel, so as soon as it goes waaeer! Tunr off the air intake tap and slowly start to add the HHO... Keep your eye on the HHO, you dont want to allow to much gas to flow, you need to maintain system pressure...

As you hear in the video, the engine then settles in for another 30-40 seconds, this is the last 2 seconds of fuel being stretched out by the HHO... Then the engine note changes again into super quiet mode, the fuel has run out! WHack the HHO tap on full and thats it!

Once it is happy you can then tweak the air mixture tap to get more power...

A good strong stainless bubbler is an essential safety device and if necessary a secondary gas chamber to allow a small buffer stock of gas in the system (Depends on your electrolyser setup)

We used a car battery for power but if you have one, a tig welding power supply will give more control over the gas production rate so you can match it to the motors needs... We had to keep adjusting the electrolyte mix until we got a nice steady 30amps...
