The oxygen. I've asked a few times of all those HHO marketers why it simply gets wasted en passant, and noone has ever been able to give me an answer.

That's part of the reason that I don't believe in the whole HHO 'ghost marketing' scam that goes on. If the Oxygen is there, and the HHO increases the combustion rate of the fuel, it also needs to increase the combustion intensity, creating a resultant stronger pressure wave over a shorter period of time (exactly the opposite of how a diesel engine works, for those who care), that should be converting the H, H, and O back into water, leaving the normal combustion gasses unaltered, no?

As potentially misinformed about the chemical reaction in the combustion chamber as I very well may be (not a chemistry major), I just don't see the "extra" oxygen being in the exhaust stream to begin with, so no further modifications should be necessary to "see a gain" from HHO, correct?

Ok, so the math may be there to support the enhanced combustion theorem (source, please?), but I still can't warp my intelligence enough to figure out where this "extra" oxygen gas comes from.
