Your information on the mole weight is noted. I hoped someone had already done some experimentation with this, but I guess not. There is one thing, though, a percentage of the gasoline in an engine never gets burned. I expect that amount varies with the design of the cylinder head, operating temperature, etc. All of the HHO would be burned. I suspect that the 1/2 would be too hot to run. Doesn't anyone out there know what the ratio is in these little hydrogen powered cars? Information that I have come across says that H2 burns in air in concentrations of 4% - 75%. Of course, the question becomes at what point does it produce significant pressure? I know it explodes with a lot of force. As the account form someone who carelessly let some build up under his hood demonstrated.
A lot of people are getting really significant mileage improvement from a small addition of HHO to the intake air. I'm just wondering how far it can be carried.
As to the figures of gasoline being 29 times as heavy as H2, wouldn't you have to divide the 29 by 2.8 to arrive at a comparison? That would be 10.35. 14.7 x 10.35 would give a fuel/air ratio of 14.7:10 or 7.5:5 or 1.5:1.
Anyway, my curiosity is piquéd. I'm going to have to experiment. Wish I coud afford an amp meter.
Thanks for your response.
