Hello All,

I have been looking into a basic engine design with 50:1 compression ratio for a experimental water injected engine.

The temperature could reach 2000+deg and injected water to created superheated steam with a expansions 1600 times the volume. and pressure over 2000 psi.

If 400c can create 100bar(1450.38psi) of steam wouldn't it be much higher if it is 1000c?

This is just a theory at this time, getting the compression would be much easier with the help of hydraulics.

What is the source of the heat required?

We don't have  much to go on. An estimated thermodynamic P/V diagram would be useful.

Hi All,

Many unknowns in this theory, so I came up with a Hydraulic compression tester up to 100:1 ratio.

This has a adjustable check valve in case pressure goes beyond 100 bar.

This will be able to test all kinds of fluids.

I forgot to add a temperature sensor.....

Yes a static test bed is truly the best way forward!


One thing we were told years back ( in this open source public forum ) on lithium and water
It is claimed that it halves the temperature (2000 C/ 3200F )
For molecular disassociation

Testing to 1000c would make the task so much easier
and you are going even higher in your test apparatus !

The previously mentioned (above) Sam Leach claim of 20ppm lithium nitrate per volume in water
at 500 PSI !
Will be so easy to test on your test bed !( compared to trying to manifest necessary
Conditions in an engine !


Better put a blast shield too …. I hope you will need it !:)


So many things can be tested for their phase change and combustion characteristics ( yes I know “you” know this already)

The first problem with an ICE is that it's not a fuel/combustion engine it's a expansion-pressure-force engine. It doesn't matter how we generate an expansion to produce the pressure which acts on the piston causing a force only that we do.

The next problem is that like most of our devices the ICE is always acting against itself. For example, we combust a fuel to create heat to produce an expansion-pressure-force. However compression heats/expansion cools so when the hot gasses in the cylinder expand they also start to cool and contract. In some low pressure long stroke steam engines the expanding steam starts to condense into water in the cylinder and it loses pressure. Some ingenious inventors recognized this fact and invented an expansion/contraction engine. Whereby the expansion did work, the medium was then allowed to condense and the contraction also did work.

So in fact there are two cycles however in most of our engines the expansion is internal and the contraction is external and does no work. Therefore at best we can only utilize less than half the energy actually present. Another brilliant inventor named Viktor Schauberger developed a way to control expansion/contraction outside the context of heat. Whereby heating can produce contraction and cooling expansion opposite to what we do. As Viktor implied, always do the opposite of what others are thinking and doing and you will be on the right track...

Efficiency
Clem engine… was that 350 hp ?
And then there is Papp
Basically magic engines that redefine efficient!!
Exploring phase change …and where it can lead us !?


Sorry Tom ….but I’m also on the road (working)
and I really feel your gonna find it
That is to say ,the phase change gain mechanism!

This test bed is the key !!

Exciting stuff indeed
