The first issue is that this is offered as a solution for an
unidentified problem. There is mention of the output shaft having
different frequency than the piston oscillation, but no
explanation is given for this being needed.

Oh, I am sorry,
Let me give a description of the biggest loss of energy output
of a regular 4 cyl engine.

It is merely a feature, not a 'loss', and it has been amply
addressedwith the addition of a flywheel.

The flywheel does not change the 4:1 ratio that it works off of
at all.
that is 4 bangs to 1 revolution.
It is a feature for "torque"
torque need not be close to that high to turn a generator.

The flywheel averages out the torque, so that the angular speed of the
crankshaft is constant. For electricity production, it is a bad
example to pick on the four cylinder, as it shakes too much. Diesel
generators (unless they are really small) are usually inline six or
vee twelve engines, as they are naturally balanced at the fundamental
and first harmonic. The number of bangs to turn the crank is of
little issue; unless the flywheel cannot provide enough rotational
inertia to regulate the speed.

The number of bangs to makea turn is the issue that burns the
gas.
It is the most important issue.
This has nothing to do with regulating the speed.
It has to do with getting more spins per bang.
And more spins per bang = less gas burned.
Simple as that.
An engine with a gearbox is just more stuff that can break or
need oiling etc...
and If you want, you can also put a gearbox on this and gain
even more revs more than likely but why add gearing at all
if not necesary.

If the cost of maintenance is less than the cost of running a less
efficient engine, you just pay for the mintenance.

The cost of maintenance is cheaper in a "less parts" engine
in almost all cases.
It again, is a very simple fact.


The faster you want the turbine to spin, the smaller the turbine
gets. Forcing fluid through a small is lossier than forcingfluid
through a large hole. You do not want a large turbine, as the larger
it gets, the slower it turns.

Correct, but the larger it is the more torque it can make.
The path of the fluid will be the same all the way through
the design.
no constrictions of size of liquid flow should be used of course.


Mass does not matter,
We are talking abotu a stationery on the ground electric production
for this engine,
It is not for a car and any auto except maybe large ocean ships
Where the mass hardly matter as long as you can make it float.

The mass does matter, as energy expended to reverse the flow at each
end of the stroke is not recoverable.

The fluid will not be hiting with a hammer type force,
It will be compressing the next stroke.
adn such compressing slows down if not stops the hammer
effect completely.
It will be more like a fast slowdown, not an instant stop.


For a large engine it is a severe problem as the peak pressure does
not just happen above the piston crown at top dead center, but is
transmitted to every surface in contact with the fluid. In a normal
engine, the geometry of the crank and connecting rod bring the piston
to a halt, in time for the next stroke. Your engine will still have
the piston and fluid moving up. Each bang afer the firs one has to
bring both pistons and the fluid to a complete halt and accelerate it
back the other wa

The pressure is not a problem,
we have metals that take such pressure no problem at all.
and even at very large forces if wanted.


What constriction(s)?
The only constriction is the force needed to turn the generator
wheel,. what other constriction is there?

The two constrictions are the entry and exit ports of the turbine.
The faster that you want the turbine to spin, the smaller it is and
the smaller the ports are. Among the larger losses of the engine is
forcing all of the fluid through the turbine.

The path of the fluid will be the same bore all the way
through the engine.
a bigger wheel will produce higher torque but lower rev speed
and the reverse of course.

Why is this design better than what is currently in use?

Multiple turns of generator for single bang.
It is that simple.
If you think that does not make a difference,
you should really think about it.
We do not need multiple bangs for one turn unless
we need massive amounts of torque.
