 Hydrogen-Boosted Internal Combustion Engines -- Scam Or Not ???
A couple years ago, there was a thread in rec.autos.tech
about devices to electrolyze water and feed the gases
into an engine, supposedly greatly increasing gas mileage.

Two web sites that were mentioned are:

http://www.savefuel.ca/oxy-hydrogen/

http://www.hydrogen-boost.com/index.html

Unfortunately, the thread wandered off into the weeds
with much of the discussion being about how you can't
get something for nothing, the energy from the gases
is ultimately drawn from the alternator, etc. That's
not the point.

The claim is that adding these gases into the
carb or fuel injection system results in burning
the fuel more efficiently -- so you're extracting
more energy from the gasoline.

Is there any possibility this could be true?
I talked to a friend of mine yesterday about this
subject, because he's thinking about ordering the
plans to build one. (I don't know if it's from
either of the web sites listed above.) He's got
lots of experience with engines and racing, but
doesn't know a heckuva lot of chemistry.

I told him it seemed like a scam, but that I
really didn't know. It's not unreasonable that
burning could be improved this way. Certainly,
the oxygen would improve burning, like a nitro
system. But, apparently the claim is that the
hydrogen is somehow improving combustion. Any
good scam will have a good story behind it.
Even if it were completely neutral on gas
mileage, after people have invested their time
and money building one, they'll be motivated
to see it in a favorable light. If they don't
do strictly scientific tests, they can easily
delude themselves into believing they see a
benefit. A lot of quack medicine is based on
similar placebo effects.

Anyone got any comments on the plausibility
of these devices? Are there any reliable tests
from trustworthy sources validating or debunking
these devices? The plans cost $150, which
further raises the scam alert level.

No, not likely.

Modern systems already do a pretty good job of burning the fuel
to near completion. There is little left over to recover.

Losses due to friction and unused heat would seem to be the biggest
remaining factors which might be improved, and this hydrogen oxygen
(Brown's gas) thing is not geared to help minimize those losses.

It is sort of like cost accounting...take into account all the factors, and
this
electrolysis bit doesnt really help the bottom line.

You still cannot get around the laws of thermodynamics.

Scam.

Think about it in these terms:

Gasoline engine bleeds power to battery for electrolysis to generate
hydrogen which is fed to engine as fuel.

This would basically make it a perpetual motion device with no net gain
in energy.

In fact there is energy lost in heat and friction to generate and burn
the hydrogen which means adding such devices to your car would result in
lower mileage.

That might not be the point.
AIUI modern engines recirculate exhaust gasses to cool the flame and
produce less NOx. It also reduces engine efficiency. Maybe injecting the
mix raises the temp back up and increases efficiency (at the cost of
more NOx).

Also water injection is an old technique of getting better mileage.

It is not claimed that all of the energy for the engine
comes from the hydrogen. Most of the energy continues
to come from the gasoline. The claim is that more energy
is extracted from the gasoline by more efficient burning,
due to the addition of the gases from electrolysis.

While you're out in the weeds, I lost a Frisbee out there.
Could you keep an eye open for that? Thanks.

If there were no improvement in the combustion of the
gasoline, that would be true. The claim is that the
electrolysis gases improve the combustion of gasoline.

any car whose combustion can be "improved" to the point that you notice
a difference needs a tuneup, not H2 injection.

We have all read the claims, Mark. The science is bogus.
