and experiment was conducted using a turbo engine and water injection. for start, the engine was dynoed using a machine which mesured internal combustion pressure, and averaged it to give a mean effective pressure (find this, multipy by stroke and you have work,(force x distance = work) eg Hp)
so water injection is good, even in ya stocker gasoline engine.
it works by the water cooling the charge of air entering the cylinder so that when it is compressed it is not in such a volitlie state.

Please don't plagiarise someone else's work and not quote the source.
The experiment you quoted is detailed "The High-Speed Internal Combustion Engine" by Sir Harry R. Ricardo and J.G.G Hempson ISBN: 0216890268, originally published in 1941, and updated with the water injection info quoted in the 1953 edition.
The water injection research was carried out during WWII and is proof that water does not combust, in fact it retards combustion allowing a greater BMEP to develop though max cylinder pressure is lower. Here's the diagram that shows the effect.
on another note, water is very wierd. at 200 atmospheres (thats about 2900psi) and 300C, it will eat anything. plastic, glass, even nuclear waste and make it harmless. why no one has made this is because no one can containe it at this because it eats the thing containing it.
Got any proof of this outrageous claim? I can think of of few examples where water at these pressures and temperatures is quite easily contained, and in certainly doesn’t consume all around it, and most certainly does not decontaminate nuclear waste.
with that, water is wierd. who knows, oxidied water is Hydrogen Peroxide, H2O2. and this stuff is a rocket fuel.
Indeed it is, but that's because it has too much oxygen to form a stable bond, (that's what the "Per" part is about) so that when passed over a silver catalyst it breaks down into H20 + O2 and releases a lot of heat so the water turns to steam, thus acting as a monopropellant, however it's much more efficient as an oxidiser and there were quite a few rocket engines that used it + a secondary fuel like Kerosene or Alcohol. In fact it was used as fuel for one of my favourite aircraft, the Messerschmitt Me163 Komet, had tremendous speed (960km/h) and rate of climb (5000m/min) but very limited range (<100kms).
However Hydrogen Peroxide is not water, so how does this relate to the topic at hand. Unless you're stating that the engine shown was actually using it as a fuel, and thus was a fraud. Fascinating substance though it is, I fail to see how it relates to the topic at hand
till you, personaly, have seen it, tried it, or know how it works, it becomes so simple as to how it works. the guy who did it said he hasnt ever opend a cemstry book, so he did what he found was right and what worked and what didnt.
If it's so simple, then please explain how it works to the great unwashed masses of Toyspeed. Myself I must be too dumb to understand as I can't see any way it could possibly work.
