Well I found one place selling a water/meth injector which claims such an imporvment in diesels:

Whoops, Not yet have found a diagram on it.
So I’m wrong. :smack:
I asked the man who owns one and is satisfied that they work and save fuel. The ones he is using on over the road service consume about 1/2 gal. H20 in 90 hours of running time so the amount of hydrogen is rather small.
I just realized something about propane fumigation and, if similar, hydrogen injection:
Since injection/fumigation only occurs during at or near full throttle totake advantage of the unused oxygen during combustion, thus approaching true or at least nearly true stoichiometric combustion, this probably wouldn’t work AT ALL at part throttle. I mean, a driver dosen’t keep the pedal to the metal at a sustained cruise, does he?
spingears, thanks - that’s a solid link. We’ve had a link to that brochure already in this thread (and a debate about its content) which came to a head-scratching stalemate. Also, I posted the names of several engineering and trade journal articles well above your post asking for “scientific journal references”. I was happy to hear that you know an owner of such a device. Does he have any paper documentation that came with it that you could scan in?
I’m already pretty well convinced that it works, but my reasoning is an economic one. Trucking companies are motivated by profit, and are unlikely to gamble. I can’t imagine a fleet outfitting their trucks with these devices unless they had participated in a road-test or seen credible results from a road test. I also can’t imagine a fleet’s owner getting bilked by a fraudulent black box and not fighting back in the courts. I make the distinction between the companies and the individuals because individuals do gamble all the time, and they get defrauded, and fail to fight back on a depressingly regular basis.
I’m still waiting for Una Persson or some other sharp MechE mind to help me understand how the chemistry/thermodynamics works, though.
Ok now I think I understand the working theory thanks to **spingear’**s link, though it can’t be (easially) cut and paste. Basically Hydrogen burns much faster then hydrocarbon fuel, when the fuel ignites the Hydrogen quickly spreads the combustion throughout the cylinder. (which I got from page 6)
