However, my engine, whether it's for steam or for compressed air, is unrivaled for now.

Well, there is one big advantage of such a crosshead. We can freely change the stroke, piston in relation to the crankshaft stroke .. For example, the stroke of the piston is the same, and the crankshaft stroke even twice as long .. Everything will depend on the demand, and what is most important in a given engine application ..
Of course, the rope has to go exactly in the axis of the piston ..
 
So that his way of placing the crankshaft, as you can see in the figure, from the side, will make the engine will be much lower ..
Of course, only for marine engines 102 rpm

What if you made Teflon so much ? 
And maybe in diesel it would be enough to lubricate them with fuel ?
 
And the rolling bearings on the crank with the grease in the middle ?
 
This ... the engine could have been WITHOUT lubricating oil. 
 
  Just what would Castrol say ?

Or maybe a carbon fiber line ?

The efficiency of a heat engine (a technical term) is dominated by the thermodynamics, the linkages used to transmit the power are a necessary but secondary consideration.

:well:   

 

Not true at all, because how will it change and overcome the efficiency of the engine, if the rotating mass will be doubled? with the same displacement? .. It determines the efficiency of the engine, and no thermodynamics ..

The temperature of the burning gases is >700 deg C and can be almost double that. Pistons are deliberately cooled so they don't get too hot, that is one reason why piston skirts are used, it transfers heat from the hot top of the piston into the cylinder liners, which are water cooled..

 

No, the mass of the engine parts has only a small effect on efficiency, for sensible designs at lowish speeds.

Such gases may have such a temperature, but the piston has as it appears in the figure, and maybe even lower, because the piston is also in large engine cooled water ..
 
And what about low revolutions, what influences the release? Maybe the combustion chamber, which has been literally unchanged for hundreds of years ? 
 
So why did the old engines, eg 1900 year , have such a small efficiency? The combustion chamber was similar to today ...
 
It was not until Ricardo changed something, but how to look at it increased the size of the chamber...
 
Okay, yes, do we continue to develop ideas ...
here one of the advantages: the possibility of completely separating the piston chamber, from the crankshaft chamber and main connecting rod .. This causes that the oil used for lubricating the shaft will not be contaminated with combustion products. He is in a clean state ... As someone will want to lubricate the piston with oil, it can use a different oil for this purpose.
However, I think that Teflon will fulfill its role ......

Feliks - your "Feliks Crosshead" mechanism is essentially the same as that used by Newcomen in 1712 in his pumping steam engine - but I don't think he invented the "straight line" mechanism - it was already in use.
Still used to this day in things like oil field production well pumps.

https://en.wikipedia...ospheric_engine

There are much more sophisticated methods of piston straight line movement - but none have proven to be any useful advance on conventional methods.

I have heard of Teflon "buttons" being used to locate gudgeon pins etc. in some engines - this area only reaches about 300 degrees C. You don't want to be around when Teflon does decompose at high temperature - I don't know if it is free fluorine gas or some compound of the gas - but it will certainly clear your sinuses.

Here all the forces in the crank mechanism ... Reduction in the stroke of the shaft twice reducing, with the same stroke of the piston causes a large increase in efficiency, by reducing the forces of inertia. Also the force Nm sometimes reaches up to 30% of gas force , which can be seen in the charts.

Andrew  :smoking:  :smoking:

 

 
 
When it does not exist at all, the average efficiency of these 10 to 15% of the engine will be higher. only because of its lack ..
 
Adding a fall in the shaft stroke by 50% from the inertia forces, even the next 10% increase in efficiency will be able to achieve ... in total, some 25% efficiency will be better ...

A traditional crosshead, usually unbalanced, to save a little on the construction .. But for this, when the command "whole back" is taken for the ship's engine, only 60% of the power can actually be used, because of this unsymmetrical crosshead, which can not withstand greater load, in the reverse than usual turnover.
In my solution, it does not matter which engine the engine is on, so "the whole back" can actually be "all", i.e. 100% ..
 
But in my solution, it may be asymmetrically, for the same reason as in the traditional one, it means that the piston is pressed down all the time, if not by the work stroke, then by the compression stroke ... (of course, it is 2 stroke ) .. Therefore, the second lower frame, can be "symbolic" and the thin line, just to keep the kinematic bond in some abnormal situations.
Of course, all this new mechanism can be in a separate housing, separating the oiled space, from the space under the piston, which can be cooled water ..
Developing further ideas for smaller engines, instead of a rope, we can use a toothed belt, whose durability is known from the mechanisms of timing ..    :D  But the revolutions can be a little bigger ..

Yes, here is the engine, in this also the piston does not beat the cylinder .. But too complicated and I still do not like modes. And the lateral force of the plunger and so-called tobaccos somewhere is lost ...
But he will read for it, what it gives ... I do not have to tire about writing the advantages of my crosshead .. :D

Star engines were characterized biggest always force density

starhalfrotate5.gif

elastic%20hose.jpg


Below picture of the star half rotate around 10 (40) with "cylinders". for the transparency of the picture one can see only 3 additional "cylinders" more than is at the animated film.
One can also see dimensions of the whole of the engine in the assumption that every cylinder has such dimensions for the picture half rotate with the set connecting rod of the Sulzer D= engine of 900 mm and stroke 2500 mm .

half10.jpg

So 10 (40) "cylindrical" engine half rotate about the same working capacity in comparing to the Sulzer 10 engine cylindrical on the picture below .

Sulzer: 10 Cylinders 20 m long , 15 m hight , 1500 Ton weight

Half rotate star : 10(40) "Cylinders" 4,5 m diameter , 4,5 m long
about 70 ton weight.

sulzer1.jpg

And most importantly.. Since in the engine half rotate mass innertia are several times Sulzer smaller than in the engine, engine half rotate can work with the much greater rotation speed.
Slzer : 102 RPM 60 000 KW

Half rotate 250 RPM 150 000 KW

In same intake work volume .

And now, the efficiency of the engine, due to the friction of the walls of the cylinder to rise about 5%. That is, it is the most efficient machine for the heat, whose efficiency exceeds 50% of the.

Well, here is a motor that does not need crosheads ... but it has 40 cylinders our stroke ..
But instead of the engine cylinders, it can be a nipple instead of a cros-heads (feliks crosheads). Just hook the ropes to the poles of rotation, and the ropes, normal pistons ...

Yes, we slowly develop this way of bypassing the lateral force of the piston .. here, that's all you have to do is one lever that has a half-ring at the end, but the other way round. This way one pulls up and the other down during the movement of the lever ... It can be used for a full four-stroke engine .. Well, see how easy we can cool the water piston ..

Does not this remind you of the mechanics drawn by James Watt ? But it's necessary to back 250 years back ..

 

440px-The_Kinematics_of_Machinery_Fig_1.

 

Hand-drawn diagram by James Watt explaining his discovery of the "parallel motion" in a letter to his Sohn: "The idea originated in this manner. On finding double chains, or racks and sectors, very inconvenient for communicating the motion of the piston-rod to the angulat motion of the working-beam, I set to work to try if I could not contrieve some means of performing the same form motions turning upon centres, and after some time it occured to me that AB, CD, being two equal radii revolving on the centres B and C, and connected together by a rod AD, in moving through arches of certain length, the variations from straight line would be nearly equal and opposite, and that the point E would describe a line nearly straight, and that if for convenice the radius CD was only half of AB, by moving the point E nearer to D, the same would take place; and from this the construction, afterwards called the parallel motion was derived."

 

 

 

Of course, instead of a rope, you can use any type of parallel movement mechanism.  :smoking:

 

 

https://en.wikipedia...Parallel_motion

 

 

And of course, it's getting higher and higher speed after that ...

Well a Watts link makes more sense than bits of string. Of course what you really need is a Peaucellier-Lipkin linkage. Might limit your top speed a bit.

So this Wats is not bad anymore .. but this string can have such a form of springs from the watch's bannister .. and then it is the simplest solution and guaranteeing higher revolutions .. obviously the ideal is Peaucellier-Lipkin, but also is the most complicated .. But after some analysis, to which the arms attach to the connecting rod, i.e. which carries the main forces, the rest may not have to be a monstrous size ..
 In any case, the use of a traditional crosshead certainly became archaism ... because with the use of any of these solutions, the side force on the crowd does not occur, and was not moved below, to crosshedas, and was liquidated at all ..
 
Also from my drawing you can see that a very easy way we can do cooling with the water of the piston ..
This can give us, due to its very low temperature, a change to Teflon efflorescence and one would be tempted to completely give up the oil.
And this is a very important matter, which allows us this construction, so it seems to me that maybe you can do practically this matter and try some teflon bearings and seals ..

Which to use? Well that's where you have to do engineering as opposed to watching youtubes. For a given stroke and rpm you can work out the required structural  properties and so the inertias and dimensions, and the forces, and the losses in the bearings. Then compare that with the losses in a conventional crosshead, and a conventional piston/conrod. Depending on your priorities you might want to consider total mass, cost, efficiency, reliability and ruggedness, and overall package size.

 

My first step would be to find out how big the losses are in a conventional piston conrod, as that gives you a bogey figure to work against. Of course you may find that a piston/conrod with a long length to stroke ratio is actually quite good, and certainly scores well on many of those measures.

 

From what i remember the piston rings actually contribute most of the friction in an engine, which means if your goal is high efficiency that'd be the place to start rather than reducing friction at the skirts. Unfortunately modern piston ring designs are complex and arcane, so far as i know all OEMs outsource both the design and manufacture to piston ring companies.

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 ..

Here are a few more alternatives..

 

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 ...

"I wonder where this side force acting in the crosshead has died?" it is reacted at the pivots that are grounded. In total it will be (force on piston top +vertical acceleration forces)*stroke/2*cos(conrod inclination angle)+a bit to rotate to the conrod+whatever is needed in the mechanism itself.

Yes you are right, she must be in these grounded pins ... Only that, in total, the frictional force coming from this force, will be very small on the small radius of the bolt in comparison to the large sliding side force of the piston or the traditional crosshead ... something similar to the side of the piston in relation to the piston pin, which only has to transfer this lateral force ... it is several dozen times easier to do .. I think that this time we have a free dinner ..

 

I think that this free dinner will still be important in other mechanical constructions also ..

 

As you can with a second person, think about the hidden new discoveries, it's easier to think about it.

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 ...

"I wonder where this side force acting in the crosshead has died?" it is reacted at the pivots that are grounded. In total it will be (force on piston top +vertical acceleration forces)*stroke/2*cos(conrod inclination angle)+a bit to rotate to the conrod+whatever is needed in the mechanism itself.

 

 

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 ..

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

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....

Such possible variations ...
It can be connected by a beam through all cylinders ..

The Watt mechanism has already hit the suspension ... now its turn to the internal combustion engine ..

"Metallica" played in Krakow on his concert cover "Dżem" with whom I worked as a sound designer in 1984-1987. Here also "Dżem" from my work time

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:
