So here in slow motion you can see how the valve works in a four-stroke internal combustion engine .. You can see perfectly the "precision" of this mechanism .. It is best to watch it on the maximum screen .. You can see how the valve is when not pressed (and then there is a stroke of work with high pressure ) we are simply shaken by the effect of spring vibrations bouncing off the valve face and inertia .. At the bottom of this valve there is a "mushroom" which closes the way to the cylinder .. But since the valve stem dances so, the mushroom also makes such movements .. A since it performs these movements, even when it is "theoretically" closed, it really does not close the cylinder tightly, despite the fact that it is subject to a stroke pressure of up to 100 atmospheres. And we can imagine how much of this pressure escapes from the cylinder, on the effect of these "supposed" small, but very spoiling cylinder tightness, the movements of this mushroom .. Because at a pressure of 100 atmospheres, we can imagine that even a small gap, however, can even drop to 30 atmospheres make .. this mechanism is economical, and produced in virtually all internal combustion engines .. And complacency that the valve will be tight, because it presses it to the seat, high pressure in the cylinder is only the "wishful thinking" of the designers of such a system. because you can see that this is not true, because the valve sways and bounces off the socket, just when it should be closed ... This film helped me understand why my engine without these valves has such high efficiency and power, because how it receives in the cylinder, these 100 atmospheres, I will never lose my tightness all the time, closing the "valve", maybe like 2 atmospheres .. Well, but the amount of energy to use will be 3 times greater than in a traditional engine ... because 98 atmospheres .. And so on every cylinder .. adding to this even 40% more displacement, and twice as high achievable maximum revolutions, it also receives incredible power ten times greater than the original factory engine ... the load. Well, to find out about all this, I had to do [for 3 years of hard work a prototype of this engine, and say that it is so, although at first it did not seem to me at all, that so much is possible .. But it is thanks theoretically, to drive a Toddler (Fiat 126), with the same power as the original, you need a motor that will be smaller these ... 10 times .. But all this can not be determined by just watching the animations of my engine and criticizing me .. You need to spend your private million dollars to find out that this is the case ... And this film also shows that it is possible with all the imperfections of the current valve system ...
Even an indicator pressure test on an oscilloscope shows us that the pressure drops, but does not show us WHERE it escapes ...

Unfortunately, the Carnot engine is only a fragment of the reality surrounding us related to heat engines .. But most try to explain it as a generally applicable law. In the meantime, for example, you can do a simple experiment at home with a "cold engine". Just pour cold water into the sink and put a screwed plastic drink bottle into it. We will see how it will change its shape due to the cooling of the air inside by cold water. Based on the change in its appearance, we see that also the engine would be possible on this principle. Everything is relative in physics .. But learning about heat omits many important physical quantities such as evaporation, freezing and most important - time. And theoreticians come to the conclusion that entropy is steadily increasing, but what about the scientific approach cannot be reconciled too much, because what will happen if this entropy is ever going to run out ?
I present here, probably the largest heat engine that a man can build (It is suitable for the Guinness book of records ) And theoretically, the pressure does not play any role in it, because the balloon from below is open .. the air heats up and the balloon can rise even at 5000 meters (record is 20,000 m), then the first balloon empties from warm air and fills the second, which thanks to the scrolling line to their tether will do electricity in the generator. Then the cycle repeats, from what we release at the top warm air and the bottom one, we fill it ... The old good principle and pressure does not play any role .. It's just a curiosity that not everything with heat is a Carnot engine ..
By the way, a hot air balloon is the longest-lasting machine in the air so far - the record is over 10 days ...
This shows because maybe there are other heat engines with higher efficiency than currently known .. Anyway. there is already a contribution to new thinking ...

Here is the thermodynamic problem .. We have in a box, in a vacuum is a set of thermal engines with generators ... Will this set be more efficient than it would be normally installed without a box?
it's about how laws of thermodynamics work on the Equator, and how on the Pole.
Different temperatures
on the Equator 40 degrees Celsius and at the Pole - 40 degrees Celsius also for efficiency and the layout of the engine will be important ...?

And finally, we have good access to this NASA CALCULATOR for flight profiles. No Java pieces are needed.
Well, you can see that there is a place on the air profile, where the speed of the air is 3 times higher than the speed of the general .. but this is only on a small part of the profile .. But there would be set turbine ..



here a link to this calculator and you can start learning aerodynamics yourself ... before the university is formed in this direction of aerodynamic energy

Now, when I was surprised by the Polish inventor Tadeusz Tański from 1925, but in my new Feliks Roller gaze, this simple engine system was created ......

This is 12 cylinder dual boxer or H engine .. name Feliks-Tański engine..
Its movable parts are a double piston, a single piston pin, and Feliks Roller with lever...



Now there is NO lateral force of the piston and the croshead also ...

Well now here is a picture as I imagine my Feliks Roller. This is the version of Felix Commer4 of course a two-stroke version. in which the main torsion forces are transmitted through the maximum large areas of the "connecting rod", and are supported at the point where they work, and do not cause bending, as in the classic crankshaft. That is why it does not tend to fatigue the matariału. and relatively long trouble-free work .. And a little lower costs of doing....


Well, of course, the masses reciprocating a little smaller ..

As it turned out, it's worth getting to know the history of the United States ...

https://en.wikipedia.org/wiki/USS_Monitor
Wikipedia

American Civil War 1861-1865. History talks about Abraham Lincoln and how he contributed to the excellent progress of technology as a result of the moment of this war, choosing the idea of ??the Swedish immigrant Jon Ericsson to implement ...

Monitor Ship

it's about the steam engine of the "Monitor" ship, which contributed to the victory of the Union, but later sank in bad weather. Since then, these genius technical solutions have been covered by the ocean. It was only after 140 years, an attempt was made to extract the "Monitor" engine, it was retrieved in 2001 and reconstructed for the next 10 years.
Thanks to this, they saw the light of day and became popular only, the technical solutions that were used there during the entire 150 years, when the ship was covered with the ocean, they were not remembered too much ..
Here, the history of the project and the way in which this ship and the steam engine was created .. here is also a movie about how the engine model works.

https://www.youtube.com/watch?v=VWn8gQ9Ykpk

I of course independently invented Felix Roller for a multi-cylinder engine, replacing the classic crankshaft, but I noticed that the engine "Monitor also had a part of my Felis Roller, and this solution worked well, in the engine 250 KW of power. Clearly, it has two such Shafts with levers, for longitudinal displacement of power. Also, the power take-off wheel is supported on one side (on the other only timing drive)
After covering the "Monitor" engine, I was very happy that my relationship had already been tested practically, but only for two cylinders .. It lay hidden under the water these 150 years .. but now everyone knows about it and can see that the solution works ... for 150 years, no one took it into account .. My Feliks Roller system I designed for 8 cylinders and 16 pistons ((Feliks Commer TS4) .. with the reception of the main power, on the crank shaft one-sided supported .. On the other hand it can be a small crank driving the shaft going to the front of the engine, driving the water pump, fan, generators and compressor, but flexibly coupled ... (as in "Monitor" driving the timing) Here is the animation that I made, showing how the main engine system The Monitor was working.



Yes, this story is coming round and that's why it's worth knowing .. This is the history of the United States ..

So since all of your designs rely on crank-like linkages, how are you going to prevent those failures?

Here in my hand the engine shaft from my new4 stroke ..

And because of the fatal mechanical distribution of the crankshaft forces, several cases of failure of the same shaft


A 8 times greater torque (first gear and differential transmission), they transfer to the wheels of the half-axle, which can be seen in the picture of the gearbox with the diverter, from the engine of which the shaft comes ...
they have a diameter of 25 mm and a long length ..
I have never seen a failure in these half-axes.
That is, to transfer 8 times more torque, this dimension is enough ..


The title is an explanation of why the classic crankshaft is a fatal construction and despite the large dimensions it bursts .. as seen in the pictures .. Here a little about the crush of such shafts, which even without load, under their own weight can be bent.
link

This is called the springing of the crankshaft.
On this link, how are you measuring this springs when the engine is standing. As a result of these crushing, the shafts are breaking up in the middle of their life, despite the fact that they are relatively thick ...
This causes a fatal rule of the "crankshaft" in its very construction.

link

SINGLE-supported cranks have no faults. Here is an example, from a locomotive, such a one-way crank in addition, on springs, which causes additional wheel movement. The power transferred is some couple of thousand horsepower ...
I have never seen damage ...


I have never seen damage ...
So a single-sided crankshaft is no longer so emergency, because it does not have this bending, as well as its design must be sufficiently strong.

And here is my design lever, to Feliks Roller, which is basically quadruple, and can be supported on the bearing in the cylinder axis, without causing any bending of my shaft ...
Only at the ends will be full bearings determining Feliks Roller

Most interesting Andrew but you won't find the answer to my question in the workshop manual, you will only find it by experiences caused by working on this type of engine.

It was, as I said a very common occurrence caused solely by not decoking the engine.
The excessive backpressure, as shown by the gauge on the control panel clearly showed the fault.
The bar magnet was used to get the broken part of the engine out, when ground correctly this part, being made of carbon steel would make an excellent addition to your tool box.
A crosscut chisel f.o.c.
That crank, sure it's not a wrist watch crank?
Think about the back pressure load on parts caused by excessive carbon build up on two strokes. Qoute./

Yes Merlyn, you do not even know how much I appreciate your remarks. because I know that I will not find them in the workshop manual ... It's good that you want to work with me with your experience. As you know, I do not have too much, because I had to find these codes in music .. That's why your help is great .. I now add my cody and maybe something good will be ...
You have noticed the excessive accumulation of carbon. Now that we have a new type of engine Feliks Commer, where there is no classic crankshaft, only pins with a diameter of 30 mm, we can approach the issue in a different way, as it was so far. These small plates do not need such lubrication as large crankshaft bearings, besides they do not even turn round, and do semi-turn .., so the lubrication can be a little smaller .. I do not know if you remember that two-stroke engines for motorcycles, are lubricated only with oil in the fuel and in a ratio of 1: 50. And these engines, completely protruding .. so I thought that my Felix Commer can be lubricated with normal diesel fuel, also with the addition of this oil, let's also say 1; 50 as we will take into account that diesel fuel already has good lubrication in the sona .. Imone would be poured into the engine instead of lubricating oil. Well, when 10 liters of such fuel are needed for lubrication, the amount of oil added would be 0.2 liters .. No and I think that this quantity would not plug the windows, because the rest would be the same as the main fuel, it would be fired without coke .. And I think that this should solve the problem of this too nagar. Simply a new lubricant oil felix, i.e. diesel fuel plus 1:50 oil for two strokes ... .. poured into the engine, instead of lubricating oil ..
It would have such advantages that in the winter it would not be too dense, and in the summer too sparse ... ... and this price is not too high ..
So even with a large amount of "oil" you would not have to worry about ... because also coke would not be created ... because, from burning fuel, it does not arise ...
I just do not know what oil companies are doing ...
here, one bottle is enough to make 50 liters of "feliks oil"

And here the drift part of the watch, which I personally will do on an ordinary lathe. The material to do this crankshaft weighed 80 KG and the shaft lasts 4 KG. It lasted for a month ...


You know how you see the problems of crankshaft production, and that's why I know it's not a simple thing ...
Here are a few examples, however, that the crankshaft is not necessarily a successful construction .. and despite its thickness, sometimes it ends ... And I will ask if ever seen such a broken clutch shaft, despite the fact that it is much thinner than the crank

Here, such a connecting rod of my idea .. For a semi-rotary shaft, it can be such, because all forces act by pushing the connecting rod to the lever .. only incidentally it is possible to act detachment parts from each other, so its protection can be negligible .. During normal engine operation, piston it is only pressed against the lever all the time ..
However, the cooperating surfaces are relatively large, and the connecting rod weight is smaller .. Formy Feliks Commer ..

What is a "Feliks Roller"?

this is the roller between the levers ... I let it be named ... I do not have to be about a larger diameter than a clutch shaft .

it's just a diagram that does not have to have a crosshead, but only a normal short connecting rod.

Here the red line is marked by the piston path associated with the lever. At 90 degrees the pressure of the piston on the cylinder wall is equal to 0, and with the traditional system the maximum .. And then we have virtually full torque ..
