between 4% up to 75%
which is great! So this means it is flammable in concentrations of 4% Hydrogen + 96 % air (but is not very powerful, since you must heat up other elements present in the air)
I would guess that you would have to test a little at a time, e.g. "play with the air intake"
I personally would use the gas mixture straight off of the electrolyzer, roughly 66% Hydrogen and 33% Oxy, then mix air from the intake.
Kevin is right about not really knowing, I have been gathering as much information as possible from all places, and even government (Sandia) labs cant agree on mixtures that are "correct".
The problem is that existing ICE's are only at best around 20% efficient, so you must put in 80% more than that in order to pre-plan the waste...thus the need for Huge amounts of hydrogen....BUT....tests show that since the flammability limits are so low that "Combustion" (explosions) are a reality at very low concentrations....
so again, since there are so many variables involved (electrolyzer design & eff, ICE design & eff, Air & Hyd mixture, etc) you will probably have to just experiment.
