Hi Rick you have just made valid point
When released into a expanding volume, Entropy is through the roof. It goes right to vapor, dry steam. Internal energy converts to mechanical energy via expansion. I would even venture to say it would react similar to an explosion, simulating the combustion stroke.
What if the water is subcritical?
It is but you have to account for the

Hi Jeremy,
I have been examining your site diagrams and comments on your 4 cycle flash steam engine and seen video clips of it. Obviously the timing and control of the injector will be critical to its success, also noting the injector could be used on any modern stea

I have been going thru all my data and cannot find the term De-superheating flashsteam engine. By reasons of convince I lost one of my only reference to this term.
Think about it this way, we have compressed superheated steam in the cylinder all that means
'so many btu value"
A pound of water has 180 btu and a pound of steam has roughly 1100 btu.
So im injecting water that has 37

Instead of editing the crap out of my proceeding post, I decided to post again
Point is that your concept of using the heat within the cylinder to create the steam is not good...
I dont agree with that, take for example a spark ignition engine. Its critical that heat is gained to produce a power pulse. Why should it be any different on a 4 cycle steam engine, its its own nature. As long

Hi Rick thanks for the reply

This is a rough idea of the cycle. The only thing that concerns me is at the rise of the map is adiabatic has no heat transfer wheras it should. At the instant of flash steam there is/should be heat transfer albeit as the Heat of rejection dictates.
Although Heat of rejection notes a decease in heat transfer which is a semi adiabatic process, there is still some thermal heat transfer.

Keep in mind I would like to explore the energy required by the pump. What Horsepower is needed to run the pump(s)? We can get to this later. Another point to discuss is the Stoichiometric efficiency. This is regarding the burner or heat source, how efficient is this process?
Ahhh my old friend stoichiometry, The combustion that the by products are just water vapor, maybe some Co2.

Please bear in mind that the experiments described here, were performed about two years ago. From the date of this writing. And this specifically pertains to moving a piston with flash steam not argon. Anyway here’s what happened. I modified a 11hp Briggs and Stratton engine to accept the L912™Injector. Then set about discharging it while i

The thing should be considered as re-using steam without condensing. That is a feature that aims to prove 60%.
Im not in this for easy construct of steam engines. I want to pioneer a more efficient steam engine.

Hi Rick,
Respectfully, with kind intentions, I would challenge the 60%

Hi Jeremy,
Your test rig and its components is awesome!
Thanks Rick.
I do get some criticism, but I dwell on other things.
OK, Your system as I see it is a combined cycle. You have combined the Diesel Cycle with the Rankin Cycle. The four strokes of your engine are defined in Diesel Cycle and the expansive work of the steam in the Rankin. You are using a hit and miss engine, exce

I know im claiming a hi efficiency on the expander of 60%. I dont know what it will take to prove that.
Just as an aside Harry is making us that are in genuine effort, look bad. 30% total efficiency BIG DEAL....
I was at Harrys shop a couple times and all they wanted me to do was to sign a non compete. I wouldn't sign it and they showed me the door straightaway...
I honestly believe Ha

Dont worry about the knee jerk reaction of my previous posts. Im not used to someone saying hey I find something interesting about that.
Im going to come clean,,, about projected efficiency I want to achieve 60% eff. some steam is being reused without condensing.

You like a solid fuel, renewable, system.
Back in the day when I was burning 4 to 6 hours a day, the only way I could, was using corn kernels as the primary fuel it was just cheaper thats the reasoning for it.
On the next combustion chamber its going to have an auxiliary kerosene vaporizing burner as a secondary on the afterburner unit..

Hi Rick,
Yes the injector valve can handle SC steam. The construction is 316L and a special graphite impregnated spring loaded seal. The tolerances are super tight and probably work without the seal.
The injector is electronically actuated. So the user can use variable cutoff advance and such. The solenoid is 12vdc with a water cooled wire. The real innovation is that its variable lift thru

Hi Rick,
Its rained the past couple days. I was thinking about doing a mock-up with all the components on film, if your interested let me know.
Im talking electronics the whole nine yards etc. There is a control panel that know-body has seen and Im still working on and the dam super-heater. But the mock up will be really close to the final design.
