RE: 4 Stroke Redesigned

[millen]

Regarding more prosaic designs, are there any view on whether https://carnotengines.com/the-engine has legs?
My limited understanding is they're looking at a broadly conventional ICE but with ceramic components components around the combustion chamber so there's much less waste heat to be dissipated and less need for lubrication except on the bottom end. It does sound a little far-fetched - not sure if they have a working model yet.

Well, as everyone on the forum knows, I started publishing about my new4stroke engine 15 years ago. By courtesy, this thread exists to this day and everyone who reads it up to that time is already familiar with my structure, and probably many like it, although it requires a deep understanding. I tried to explain it successively. But now, courtesy of SAE, I can also enter the competition. annually organized by her - "Create the Future". Here is my application for this competition.

And I think that forum readers know even more about my project than it is described there. Thanks to this, they understand it better and can vote for my project. But for credibility, in order to apply (and not only to mine), you need to register on this page, here: https://contest.techbriefs.com/account/registratio...

Can you explain how the foils work?

I can't see what's driving the flip in pitch... Also, the trailing foil will be sat in turbulent air from the leading foil.

Any plans to cfd model it?

You should take a look at https://www.youtube.com/watch?v=VUgajGv4Aok

Note that this is genuinely a wind powered vehicle, not an over unity device like some of those wierd ideas you've posted here.

Just watched that... Enjoyed it. Thanks.

Just needs wings and it's a 100 page PH thread

This is just an extension of my idea, which I published 6 years ago already ..

https://youtu.be/evC5y0wgOVM

And, contrary to the drawing, it is not about a vehicle, but about the production of electric energy in a large dimension .. also ships can be such modern sailing ships ..

Of course, there may be many wings, one above the other ..

That's disappointing. As a vehicle, it's an intriguing challenge to understanding of leverage and speed. As a power source, it's just an unnecessarily complicated windmill.

Well, finally closer to nature Doesn't it remind you of waving birds' wings?

So now it will be further about this climate warming. Here is the evidence that CO2 is not a greenhouse gas because it is twice as heavy as air, and it sinks to the ground itself, where it nourishes all plants (that's why grass grows so fast). And it does not rise to the atmosphere and therefore has no influence on it.
Here is a video of a miniature chimney in a power plant and you can clearly see that CO2 flows out of it and immediately falls down. Exactly the same happens with CO2 flowing out of a real power plant chimney, after some time ..

In this second film, at the very beginning, you can see how the band "Śląsk" stands in such "smoke" made of dry ice .. and it also just walks on the ground, without any lifting. So it is clear that CO2 cannot be a greenhouse gas. know, please do not tell about any "carbon footprint" anymore ..

Quoted for posterity. Following the same ludicrous logic, the next layer up from the ground is oxygen so we can breathe. Lastly, the remaining 78% is a thick layer of nitrogen above the oxygen, and that's why you can't breathe on top of Everest.

Before you call someone's logic absurd, he first takes a look at his illogical arguments. The weight of Nitrogen and Oxygen differs only by 10% and this allows them to stay in a mixture, which due to the movement of warm-cold air causes them to mix perfectly. On the other hand, the weight of CO2 is almost twice as good, and it is not so easy with this mixing. Well, unless for posterity a few who do not know about it, they will remain funny forever

Yes Ram Induction is important. Good thing in my new4stroke engine it is essential .. But also "valves" have an opening angle of 360 degrees (!) The precursor of this was Walter Kadden.And in the 80's there was no internet yet, and you had to look for news in libraries ... here one from Peenemünde, which I found some information for my exhalations
https://en.wikipedia...i/Walter_Kaaden

Here's more about this dynamic engine boost:

https://www.macsmotorcitygarage.com/secrets-of-chr...

So now I will try to authenticate the received power of my prototype ..
Well, in my opinion, you should simulate all the capacities of all 3 cylinders with pistons, because they are involved in every engine cycle, in its entirety.
we have this - The main piston has a capacity of 297 cubic centimeters
The suction piston has a capacity of 181 cubic centimeters
The exhaust piston has a capacity of 79 cubic centimeters
i.e. the sum of one engine cylinder is 297 + 181 + 79 = 557 cubic centimeters, i.e. with two cylinders, as in the prototype it is 1114 cubic centimeters.

Now, due to the very quick opening of the ports, the forces resulting from the induction frame (dynamic boost) are much greater than those of classic valves. Therefore, the entire space as shown in the drawing is perfectly "flushed" with fresh load, up to the maximum capacity of all cylinders. So it is possible to fill this 1114 cm volume completely ..






But now we have the displacement of the pipe between the carburetor tank and the cylinder, which, due to its inertia, will also fall into these cylinders and will not be retracted as with a classic cylinder, and will supplement the already sucked load.





The capacity of this pipe for one cylinder is about 400 cubic centimeters (diameter 5 cm and length 22 centimeters), i.e. for two cylinders it is 800 centimeters, which will be added to the previously calculated displacement, i.e. 1114 + 800 = 1914 cubic centimeters. that is, my prototym really sucks about 2 liters in capacity, it is no wonder that at 10,000 revolutions per minute, it will give us a power of about 250 KM .. (BMW 2002 ti at 10 000 rpm)




Now do you believe so much is possible ?

Do you think you are the only man in the world who knows about engines?
But cheer you up, I thought so too, and only a certain event changed my view on the matter ...
it is known that the ratio of air to gasoline, in order to be flammable, is quite a narrow range ... so if we overdo it with air 3 times, it can be quite bad, ..
Here, from another forum, a story about how I changed my mind ..

Quote: [quote=Merlyn post_id=16196 time=1626184004 user_id=2190]
Well reading between the lines here Andrew concerning the " I almost lost my life during testing " speech I am fantasising here and my mind is depicting you peering over that front pulley with that top of the range " membership to what tie on " and being drawn mesmerised into trying to ascertain which direction it is running in ( clock/anti-clockwise ) all at the expense of being introduced as yet another belt in the equation.
However it hurts just as much whatever the rotation unless you become like me when observing close ups during testing.
i.e.
Tie Less.
Or was it that quick reaction ducking when that rod sailed over your head with your name written on it?
Am I close here?
Just wondering.

Well, Merlyn, it's good that you write about your doubts, because probably other readers may have similar .. Besides, I have the opportunity to properly explain what may be the cause of doubts .. in my life I had two such chiles that did not last long but they stuck in my memory .. one is like a narrow road, at night, at 150 Km / h, I suddenly met a car on the way with similar speed .. Neither I nor he was doing, despite our driving, we were driving at full traffic light. We simply met at the top of a hill that was perfectly covered with bushes ..
Second time, when starting my engine .. In the three months that I started it every day, the engine has not been able to run faster than 3500 rpm. I did a lot of things, messed with exhausts, ignition, carburetor fuel jets from 120 to 240 and nothing. The engine, like enchanted, did not want to spin above the 3500 rpm. So after so many unsuccessful attempts, I fixed the carburetor throttles, permanently, with a wire at maximum opening, because the engine did not want to move higher .. I thought it was some kind of resonance, I moved the ignition device and similar things on the run .. And the throttle carburetor open to the max with this wire all the time. I always turned off the engine with electricity, cut the circuit to the battery ... But one time, standing next to it, I did not want to turn it off electrically, and I broke the gas tube, because I wanted to mess the main fuel nozzle again, and I thought that when replacing the nozzle the gasoline will spill anyway, so bending this hose, waiting for the engine to burn out to the end with the one that is still in the carburetor. And so, standing next to the engine, I was waiting for the moment to hold the engine (the throttle was tied with a wire full) and after a good moment, suddenly the engine was spinning at enormous speed of 10,000 or even 12,000 rpm / and it stopped immediately as a result complete lack of fuel .. Very scary
, because as an engineer, I understand perfectly well how it could have ended .. but I also understood what "hurt" my engine .. It turned out that the engine has too much fuel .. in relation to the flowing air .. The original nozzle of this carburetor in the bmw 2002 tii engine, has 135, and the cylinder that sucks 500 ccm .. I started to change the nozzles (after making smaller ones) and it turned out that the engine only works perfectly on the 80 nozzle, and easily screwed up to 10,000 rpm. My engine per cylinder has a capacity of 300 ccm .. And then I realized that my engine is about 250 HP, because the nozzles change their capacity with the square of their radius .. that is, the 80 nozzle is square 1600, and the BMW 135 nozzle is 4556 square, well over twice as much (2, 8), which is my two 600 ccm cylinders, the same as 6 BMW cylinders, i.e. 3000 ccm. Would you like to spend? So my engine is as powerful as a BMW with six cylinders at 10,000 rpm.
Can you imagine a 250hp engine quickly reaching that 10,000 RPM at full throttle? Now you understand that I am not exaggerating.
And now always take me seriously, because my engine design turned out to be fantastic, and had it not been for this incident, I might never have known about it. But I found out and communicated all this, that it is fantastic, I have a prototype to show with this 80 nozzle .. Everything depends on YOU



Well, it is good practice to re-learn this engine, but I think it will have to last as long as your learning about the old engine lasted .. Because why could it last less?

On the contrary. There are many many people who know more than me about engines. They would all say "Nah."



Sure, you made a poll among them, what do they think about it ..

Anyway, if they knew about it, they would have produced such engines a long time ago .. Because why couldn't they ?? :lol:

They are probably surprised that it is possible, however, more than they have imagined so far ..

Besides, they would have to learn so much ... so I prefer to keep saying NO .. :lol:

But this time it starts to be unfair i stareomie just not enough anymore ..

And here you have a book from which you can learn about classic engines .. so much that you have to reject 95% of this knowledge because this time it is unnecessary ,, but in its place you have to replace it with a new one .. which Wuzak will probably show you in depth ... :smoking: :smoking:
