Thanks rusty, been a long time since I did any serious chemistry, not sure I entirely followed that, but the effect is similiar to higher initial cylinder pressure (i.e. higher compression ratio or more MAP) AFAICT. I just want to be careful with the comparisons to HCCI (high compression, fine grained EGR control, and lots of it, direct injection).
Meanwhile hho is purported to have an octane rating of 50ish, and (in addition to heating the fuel/incoming air) would increase the likelihood of preignition. Whereas direct injection removes that possibility, for all practical purposes.
You don't believe HHO is on it's way to %50 efficiency, or do you?
