Heat engine?
Why?

It transforms heat from your fuel to mechanical energy. That's a
definition of a heat engine.

Okee dokee,
no prob then,
Heat Engine it is.
but that still does not stop it from being better than
a traditional ICE.

First, it has no hardly any through space which is the biggest loss
factor, second, water wheels that used the correct amount of water
are not inefficiant at all.
20 lbs of water in a bucket falling and in turn getting 100's of lbs
of force
from such is hardly inefficient.

That's pretty much a non-sequiter.

Why would you say such?

I didn't, I said paddle type wheels are less efficient than propeller
type. That's why commercial windmills use propellers and not some
sort of paddle arrangement. That same is true of hydro. Hydro is
probably closer ro what you are claiming, it will operate to close
tolerance on its turbines.

Don, any idea on the upper limit to efficiency from Hydro generation?

Hydro from a dropping water source is still a bit different.
but I suppose it will be at least the same efficiency.

I can see you did not see the website?

I did, there's nothing but an assertion there. I think I see what you
are getting at, it's just completely irrelevant to your efficiency
assertions. Unless, of course you can show that a small fast propeller
is more efficient than a large slow propeller.

It is not a propeller like most propellers.
It would not have the "through space" that propellers have at all.

If I understand that rather sketchy diagram, you plan to have the
combustion in one cylinder push your working fluid through a generator
and push the opposing cylinder on an exhaust cycle. Then you repeat
with the opposing cylinder. Basically an ICE driving a hydraulic pump,
driving a hydraulic motor driving a generator.

Yes, basically .
In short.
1 bang for many turns of the prop instead of 1 bang for 1/4 turn like
a 4 cyl engine would do.

It also seems condemned to be a two stroke design.

Yes, kinda, but you could make a 4 cyl version
but at 2 cyl at a time would have to be synced

The length of the stroke is the key.

Which plays no role in efficiency. There is no reason that a longer
stroke will derive more energy than a shorter stroke all other factors
being equal. The only way for this to be more efficient is if flud
coupling is more efficient than mechanical coupling. That you have to
justify.

You do not see the length?
The stroke could be as long as the bang still pushes.
in some cases you might even be able to make a 20 foot stroke
and that will turn the main shaft a lot more than a single bang
fom any ICE of today.
A linked crankshaft is limited to 1/4 turn per bang of the main shaft
of the engine in a 4cyl.
The "super long" stroke could create 20 or more turns of the main
shaft with ease.


The engine on the website is the same "heat loss" as a normal ICE
per bang except the fact that less heat is generated per revolution
to begin with.

Then it will be less efficient. Lower initial temperature means a
less efficient heat engine.

It will not have lower heat in the bang itslef.
It will only run cooler because of the time it takes to
make the stroke complete.
There would be no extra loss because of such.


As an aside on what basis do you assert the temperature will be lower?

Basically the stroke will take longer to finish.
That would mean less heat "per second" so to say.


I did, as I said before it's a just-so story, not a design.

It is a design that needs people to look at and fix small problems
so far. no "physical nor mechanical" problem has been noted.
It is also better than throwing the pressure that could still be pushing
the piston in a normal ICE right out the exaust port.
In theory, it also might be much quieter and may not even need
a muffler at all since it will be mostly blowing much less compressed
air instead of releasing the bang because the piston can not travel far
enough
to capture the whole bang.
