Yikes.......
HHO, equals HH (2), O (1), unless I missed something !
You can not break it up any other way. However, it's the way you break it up and prepare it for consumption that makes all the difference. A little something I hinted on in some early posts, ................ Restrict and polarize the open air to the intake(through the throttle), then you have NO need to separate the two during electrolysis.
As well the type of water you use is also a major help. You have a difference in water as whether it's distilled or not. Many types of water can be used but I have found that what is called Heavy water is working extremely well. You will have to look up anything else as I am not your typical HHO user as those here. If there is something I don't answer, don't be mad, it may not be something that I will answer.
Also you may not want to use Heavy water as I'm not sure how it reacts to different electrolytes. I use no additives except alcohol for freeze prevention. Which I didn't use in time this winter and busted a cell in two.
Good luck
Its done right or its not done !
Hail HHO.
