My project Feliks Commer T4 engine will have about 500 hp, with a weight of about 500 KG, here you can make such a stellar version put together 10 engines (on the left and on the left side of the star) It will weigh about 6 tons and had 5,000 HP. .. It will be suitable for the propulsion of a small ship .. or for the production of 5 MW of electric energy .. with long durability and efficiency ..

In the whole engine there is only one bearing in the connecting rod. The rest are half-turn pins. So, the engine's failure will be significantly increased.




here's a discussion on how to match it to Formel 1

Here is the solution for a normal 4 stroke engine ... it can be 2 x 8 cylinders with heads ... And this roller is common to everyone, it can have diameters ... clutch shaft ... .

Yes and in this even 8 cylinder engine (8 x 2 piston), only one crank and one "real" connecting rod .. ..

Do you know how many reciprocating masses less?

But I like my cartoons ... here is what the prototype apparently traveled over a million kilometers .. Well, but I would certainly do without 2/3 crankshaft and 4 connecting rods less ...

and here, in this photograph, it is perfectly visible that if you replace these connecting rods and the crankshaft for these 3 additional cylinders 9 Next 6 pistons), for which you can clearly see that the place is, and outside put one crank with two connecting rods, then the strong , pratically with the same dimensional parameters and the same could be more likely to have TWO TIMES more power ... If like comon rail to use, then surely and the plane would be suitable with such parameters ..
One idea was enough.

Well, if we were to convert the Rootes T4 version, then it would be 400 Hp with a good speed for the propeller.

Here in the movie you can hear that when they "defraud" it's almost like Formula 1 rolleyes
And it would be twice as good ...

A small crankshaft at the front and an additional lever ... I would have put in a good turbocharger yet, but I would leave mechanical roots, too...

"I'll take real data even though it is hard to understand, compared with cartoons, thanks."

because if they learned from such scientists, which draw their conclusions a bit, it's no wonder .. And then they do not know what to pay attention to, and they deal with matters that are not very important, not important.
Strength tensions piston rings is `5 KG, and the side force of the piston is 150 KG, For them it is" half ".. :laugh:

link Rings

link Piston

It's good that you know someone who will lead you out of this error

Andrew

Eat here and imagine that this side force is one-tenth of this force which has been hit by a connecting rod ..



And in the era of steam engines, they did not know what the water cooling of the piston might be useful ... I know ...

"You think that 15% of the IMEP is absorbed in sidethrust on the pistons? Don't think so, most of the FMEP is piston rings."

Well, unfortunately this is not true ... But so far people have thought so ... If you liked playing with a calculator, which I published a few posts above, then you probably already knew how much the reaction of the piston to the cylinder ... Publishes again with my setting value, and clearly see that this force reaches even 30% of the value of the force giving the torque .. derived from the combustion of fuel .. Contrary to appearances, the force of pressure on the piston ring piston is small compared to this force, because it is in the pressure of relatively the small force coming from the bending of the piston ring, which, as you probably know, we can easily squeeze with fingers ... ..... So that the force in comparison to the force of lateral force is many times smaller, if the engine performs heavy work .. And is independent of the load of the engine, it has practically constant value ... independent of the engine load.
Here you have a screen shot in the picture, because as you can see, you do not like to play with calculators.

Principle of operation of a 6 cylinder engine with a crosshead, Watt type, Peaucelier or Feliks line crosshead .. So what gives us ... no friction piston by cylinder, so we can give up the oil for lubrication (oil pumps too), and gives 15% torque increase. Possibility of excellent cooling of the pistons with water, which will increase the compression ratio by 2 units. this is the next 10% .. Well, ecology, no oil burning, and less NOx, because in the chamber lower temperature ..

And the lack of crankshaft, because one crank with the connecting rod is hardly called a shaft ... if the engine has 16 cylinders .. :rolleyes:

Had the twilight of long crankshafts ready to be ready ... ?



The connector between the arms as they will have the diameter of the main bearings of the main crankshaft, this should be enough....

Always every two connecting rods and two cranks on the crankshaft in a 4 cylinder engine are always less .. :cheesy:

It's best to see in such a drawing .. so dead force can only give one's place on the casing in one place ... only pivot is in the place, which gives very little resistance to movement on a flat plane .. an element loaded with this force ..

Here are a few more alternatives..

Such animation, so that we know what we are talking about ..



Well, here's the crosshead but it's applied to my new 4 stroke ... we gain a lot ... for my experience with this engine, we now get 1 liter capacity of the main piston, about 300 hp at 5000 rpm.
Of course without NOx, because the pistons will be cooled with water ..
Well, that's what to fight for ...

And nowadays, how to design an engine that will save 10% of fuel in the ship's engine, because there is no friction in its traditional crosschead, then here you can see and count how much it can be ...

Which to use?
This is a good question ..
With a new construction a lot of unknowns ... here is one but also a new 3 ways to connect the connecting rod ..
And not only the mathematics of movement, but now all force must be determined ...
A lot of work for sure ..



I wonder where this side force acting in the crosshead has died?

Historical notes
Sylvester (Collected Works, Vol. 3, Paper 2) writes that when he showed a model to Kelvin, he “nursed it as if it had been his own child, and when a motion was made to relieve him of it, replied ‘No! I have not had nearly enough of it—it is the most beautiful thing I have ever seen in my life.’”



Which of these three mechanisms to use ... and here the magnitude of the lateral force on the piston in the C-spot ... as you can see on 1/3 of the torque it achieves .. THEREFULLY IT WILL NOT BE HERE ... :clap:
