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 ...

In a world with no wind perhaps

10 days aloft is chump change. That is almost a holding pattern over LaGuardia.

Try 64 days

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 ...

That looks like quite an old motor (design).

Do I see pushrods?

In this film, you can imagine that on the other side of the valves there is the same disc as at the top and of course the wedges when it is to be closed, does the same at the bottom as this disc at the top of the springs

Well, here in the film you can see that the valves are almost not open at higher revolutions .. The same is seen this opening, the air that is to enter the cylinder ..

And the sound that this mechanism produces is huge .. You can take my word for it that the whole sound (95%) of the four-stroke engine comes from the timing mechanism ...
My engine has only 5% of this mechanical sound,

But on the exhale ... world record ...evil

Did you like my balloons? It is a buoyancy engine .. There are already such, but operate under water .. are exceptionally fuel efficient vehicles, which you once, then 3 seconds using energy and emerges again up .. Of course the circulation of Carnot have nothing to do, although in the level covers considerable distances but the faithful his followers will try to convince us that they have ... But they do not have an orthodoxy should not be ... despite teach this way at universities ...
First about the underwater glider, of course in English .. https://en.wikipedia.org/wiki/Underwater_glider

If someone needs it, you can already buy it ... maybe even a sailboat would be towed

Technical parameters .. http://www.teledynemarine.com/Lists/...VXQ4yHh0ayJsSM

We develop thinking further, not burdened by this Carnot ..

Do you know how much engine power goes to overcome losses in the timing mechanism? When designing, it is assumed that it is 10% of the maximum power of this engine .... But, after all, it is very rare to use the full maximum power .. to maintain speed in the city - 50 miles, usually not more than 20% of this is used maximum power .. .. But then the same amount of power goes to the camshaft ... as if we used the maximum power ... So, in fact, in driving in the city the timing drive goes up to 50% of the power used then ... we still have to overcome as much resistance as braking with a 4-stroke engine. I learned about it when I was driving a car with a two-stroke engine, which practically did not have engine braking ... So in summary - the timing drive and pressing the valve springs - I think, on average, there is 50% of the currently used power, which we need to overcome, thanks to our fuel. .. believe me.

Here, such false graphs are:

https://x-engineer.org/automotive-en...4V4_Mba2uTqzBg

There was once a discussion on this subject .. I used to think so until 1980 ... But later I looked at it differently and I know, as a result of years of reflection and experience, that all this is sucked from the finger, these heat and mechanical losses, unfortunately .. Here is an evident example showing that the resistance to movement of the crankshaft and the camshaft is several times larger, so these charts are a complete fairy tale ..
And that's why they are not building new efficient engines ... previous engineers. and until they revise their views, they will not build a better engine .. Here you stubbornly do not see that my engine with the same capacity, the main piston sucks 3 TIMES more air into the cylinder, and you try to compare it to a traditional engine that sucks 3 times less ,, And you say that the losses on my pistons according to these graphs are much larger .. Yes, maybe (but I'm not sure) but they suck these 3 times more charge into the cylinder and This is an undeniable physical basis, but my engine must be more efficient , no matter whether you acknowledge or not...


You can see that the shaft itself is very light, you can turn the hand, it is very difficult to mount the camshafts, even using a long arm wrench .. I think that even 5 times more force is needed for this .. I used to rotate several engines that I modernized and I repaired and I know that this is a big difference in this strength .. And this will also be confirmed by every efficient engine mechanic...
And that's why modern engineers, unfortunately, put them down and are unable to make a working engine from 23 HP to 250 HP ... and until they start to find out, however, it is, they will not do it ... And I do a lot so that they deign find out ... until health allows.



These and this graph shows that the valve train movement resistance, despite increasing the turnover by 6 times, does not consume more energy .. It's some wonders, because they also have their inertia, and bearing resistance also increases, similarly to the resistance in shaft bearings crankshaft ... and as a result of increasing turnover from 1000 to 6000, this green space should be much wider ... .. and this indicates a very unreliable development of this chart. Because the valves also have their inertia, which increases with the square of revolutions, and thus the friction in the drive system of these valves also ...

And here, as if someone wants to calculate the displacement of a new engine ... and thus everything you need then, is different from the current engine ..
and the first weld, which you will not see on the animation ... that the minimum volume of the combustion chamber is 370 degrees of rotation of the main crankshaft ..
