We also had water injection on the early (pre G model) B-52s, and early KC-135 tankers.  Hence, they were affectionately called "water wagons".  Those early jet engines had horrible acceleration for takeoff.

Huge plumes of black smoke on takeoff, sucking fuel thru them like nothing else could.  I can't imagine how it could increase efficiency.

I never got to fly any WW II fighters, but remember reading about War Emergency Power, or WEP.  WEP was, as Mick said, just more throttle that allowed the pilot to exceed normal red line in manifold pressure (not RPM) to get away from the bad guy.  Use of it trashed the engine.

Kinda like our technique in F-4s to get away from a Mig 23 or 25 - full afterburners, dive for the deck, get as low as you could go, and run like the dickens home.

Other's don't think it's a scam:

I've read other stuff saying HHO is viable..but not miraculous..

Gort.  Thanks for the dialog.  I really don't know what automakers would/could do with any technology.   They don't seem to do too much of anything with engine advancement, particularly with MPG improvement.  Traction control - yes.  GPS and Diagnostics - yes.  Aerodynamics - yes.  Engine/MPG improvement - no.  (My impression...maybe not others)

I just look at autos of today and notice that they don't get any better gas mileage or performance than my first car I bought in 81.  In fact, my '81 Plymouth Champ got better gas mileage than any car on the market today...even they hybrids.  How can that be?  And what makes me more upset is that my dad's 2002 Corvette gets better gas mileage than my 2001 Toyota Highlander.

Now you can say what you want in defensive of automakers.  But in my opinion, they are just as much a part of the gas problem as anything else in this county.  Why?  Because people will pay for glitz and not innovation.  As long as gas was reasonable, people didn't care what the car's MPG was.  Now it matters to people, and automakers don't seem to want to change.  Why?  Because eventually people will accept the current price of gas (just as they did before) and keep buying whatever new glitzy crap the car companies provide.

In 20 years look what we've done with computers.  In 20 years, we sent men to the moon.  Look what we took airplanes from in the last 100 years.  But the 100 year old automobile engine hasn't changed much, runs off the same stuff, and gets pretty much the same (or less) MPG.  Yeah.  I believe the auto industry is doing everything it can to use technology....sure they are...

  I think the average car like chevs and ford get a lot better mileage than they use too.

Here is what I did to my '71 Wolseley 16/60.  The engine requires high octane gas.  I wanted to use regular.  Doing so caused it to ping, knock and diesel when you turned the key off.  So, I used cooled Marvel Mystery oil to solve the problem.

The goal was to reduce combustion temperatures which would reduce the need for hi-octane gas, as well as cause the engine to run cooler.

Upper Cylinder injection systems are very similar to water injection:

I have the one using the metal can reservoir. ( You don't want to use the plastic or glass units as they will insulate the oil from the airstream).   I mounted the can in the front of the car where the airflow hits it.  This cools the Marvel Mystery Oil ( a simple, lightweight oil that will not burn in the engine's combustion chamber) that is in it.  The oil is then sucked ( by engine vacuum) through a small transmission cooler, which is also in the airflow in the front of the car.  This cools it some more. It then enters the intake manifold via a spray nozzle, where it is distributed to the 4 cylinders via the intake valves.  It gets sucked into the cylinders and pushed back out, via the exhaust valves, and then out through the exhaust.  It never burns, in the cylinders.  This results in a cooling of the combustion temps of the cylinders.  The way I know that it is doing so, is that with this simple system, I can use regular gas  in this engine with no pinging or dieseling.  If I stop the flow of the cooled oil, the engine pings upon acceleration and diesels at shutdown.  

The Ampco unit's flow rate is controlled by a metering valve on the container.  All of this could be duplicated at home, and you can buy the spray nozzles separately from  Vaco, Inc, P.O. Box 6, Florence MA 01060  (413) 586-0978

Perhaps a system like this would solve your specific needs?

2 cycle oil will burn in the combustion chamber and leave its soot behind. Thats why you see all that smoke coming out of a 2 cycle exhaust system.  Marvel Mystery Oil or Redex will not burn in the combustion chamber, and leave only lubrication behind.

I've had 3 2 cycle motorcycles and a lot of snowmobiles that didn't smoke
