Wow, a very interesting topic.
Getting back to the original engine concept, back on page 2 of this thread, 4lf4-155 asked "....but what are the benefits of doing this?"
I don't think this was suitably explained (although I may have simply missed it, in the 18 pages of responses).
I believe the answer is in the PV diagram that was shown much earlier. The compression stroke and the expansion stroke are not symetrical. Most of the readers here understand that a higher compression ratio engine is more efficient. Buts its not compressing the air that does "work", its expanding the air.
This engine could, theoretically, be more efficient by have a high expansion ratio while maintaing a reasonable compression ratio.
Ok, thanks, with zauwazsz very complicated relationships in this engine. Some even try to describe them. It can brighten a lot of things.
I also am a mechanical engineer from internal combustion engines. My thesis I made the first prototype engine. he had a 3.5 hp power, and I was very pleased with this design at all worked so quickly
When I stepped outside the magic circle outline of the cylinder, it turned out that I have much better
Next I decided to make a prototype, but so to the races. All the assumptions made in the project was envisaged to power about 100 hp. When designing the engine, I knew that if I could get such power, then I'd be happy.
On the project and making the engine and research in motion spent about 1000 days.
Of course, well have erred, and if not for the positive experience with the first prototype, then at some point I gave up work.
I write these numbers are not there to praise my designs (though worth it), but so that future contractors did not commit the same mistake as me in compounds, because then it prevents the use of the engine, because it will simply disintegrated from overcapacity.
Until after I learned about all that at the end of the engine tests, and the messages they are possessed thanks to my work. Later we began analyzing, whence so great to be able to take. And believe me, everything has its reasons.
and Now, I would not have heart, if I had not shared this information. But also, no one would have no heart, if not further develop this design. Because it is a surprisingly promising.
And I say now that the next engine will have 420 hp with a capacity of 1000 ccm,
At 10 000 rpm, and it will be a diesel.
So they say my experiences.
And it consists of many elements, and advantages that you need to teach about half of the academic year.
The engine looks simple, but its proper design requires a lot of the west and coordinate data.
Almost all of the information, what are the traditional engine, the changes are enormous, so that past, are hardly useful.
I think that just by motor sport should promote the construction .
It's just that not everyone smiles almost from scratch to learn the internal combustion engine.
I think that the decision had already been taken, but is not yet known when the study will begin ..
Because we have enough teachers ...
I already have this distance of 35 year old, and says that we have the heart to this structure.
This is really the only way to know everything, and why do we think this unlikely. I experienced it myself, so I am not surprised at anything.
As mentioned, this engine different from almost all existing structures, although the animation looks very friendly ..
But the present one case, for example, I did not encountered in traditional designs. Such matters is much more.
And it has a very significant impact on the derived parameters.
Watch the animated film exactly, and look on how the smallest exhaust piston is on a big crank. Notice that during the ignition the crank is finding him on the maximum arm of the crankshaft (About 70 grad post TDC )
And the maximum working pressure of 3 times smaller ,than the piston surface area of the main piston, but it is the crank arm 6 times bigger. In total, the smallest exhaust piston, and so gives 2 times longer, torque to the system.
This case makes it to the receiver should power the whole engine with the upper shaft !!
This property, it causes that the right engine is the engine of the upper shaft, and that the bottom is only fast charging pump.http://www.new4stroke.com/silnik.exe
Also, the smallest chamber combustion, isn't, as this way as in the normal engine in 360 deg. As things are now minimum chamber (largest compression ratio) it is around 370 deg game piston . Therefore generally we are making a profit on the torque.
I think that even half a year and we will fully understand.
