Hello Andrew, I know you love a good venturi tube, did you know they use them to extinguish oil well fires?

Or maybe a two-wheel car would do ... There's no need for an differential and anything .. see the Segway
There is no steering wheel, and what's the return .. because let's say on wheels 1.5 meters in diameter ... for every trimmer will come ..



Such a Segway with a comfortable seat and visor, it could be called Feliks Car

A two wheel'd vehicle with a seat and windscreen?



That's a bike mate.

So, while I was interested in the development of my Segway Car Feliks, I found some helpful solutions on the web. It turned out that with the help in developing motorization, come ... Disabled and their machines .. It's such a Segway with a chair because after all the disabled can not stand ....
And there are companies that Segwaya adapt to them ...
Now it's enough for such a vehicle, make a canopy with doors and windshield wipers, teeth do not reach us, a phone holder in which there is a speedometer and other important things, and the front energy-absorbing plastic bump so that not immediately at what, With your feet flickering .. after you get the blinkers, the vehicle becomes a capable Segway Car Feliks ..
I also see the way to develop such a car, not even a multiplayer, with the increase of wheels and the use of such solutions .. but not for acrobatics and normal driving ..
Also, I think of a small diesel engine that drives an alternator, and this whole 15kg system would give that car an unrestricted reach, of course when adding gasoline. But not much, because my four stroke engine would be as good as 30 ccm.

Here are some examples from the internet ..

So I have to thank that good people brought me to the ground with my Segway Car Felix ... I of course have invented it completely unmistakably, never seen such a solution .. But I was provided with my much earlier (2011) professional Segway rules here a few photos. As for Nisan's solution, it is quite complicated.

Well, this is my new idea ... I decided to get rid of force, guide the piston ...
*This gives an average of about 10% higher efficiency of the engine, because we do not waste energy on friction .. In marine, eolnobrotowych, so far used to be used crosshed.
Instead, I used such a machanism, based on oil like a pump, with a rope as a working element .. Because the rope can not be "pushed", I put the other such arm in motion to the other side .. And from this simple connecting rod driving the crankshaft. Thanks to this, there is no side force anywhere in the whole mechanism .. It is in a traditional design, very large force, reaching up to 1/6 of the total force in the connecting rod driving the crankshaft .. Here its size is calculated .. I think that the average 10% of the engine's reliability will be obtained. The engine has very small orots, 100 rows per minute, and I think that this will work ... In the steam locomotive, we will get rid of the slider, and its efficiency will increase significantly ..
Certainly the demand for oil, which suppressed this large friction, will be much smaller ..
Maybe someday it will go to F1

The film shows that with 3 movements of the arm, the vehicle travels about 10 meters .. with a piston stroke of 50 cm, having 300 cubic centimeters of air, a liter will travel 30 meters .. from 100 liters 3 km, and from a pressure of 200 atmospheres 60 km. .. 10 such tanks, and we have a range of 600 km .. 100-liter tank is a pipe with a diameter of 24 cm and a length of 2 meters in a square meter will fit 16 such tanks .. ie in the tank 1 m x 1 m x 2 m, 200 atm, it we have a range of 1000km ... I am wrong somewhere, because through my miastenia , I have a double vision .. Such an idea for a Polish family-owned electromobile car .. And it is with us (Poland) REAL, most importantly ..
No Tesla ..


with a simple and light, cheap engine, pneumatic cylinder .. Just 3 cm in diameter, if the pressure is 10 atmospheres ..

[Feliks]

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 ?

moking: moking:

Or maybe a carbon fiber line ?

[Feliks]

we lost forge Nm


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 ......



Andrew

[Feliks]

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.

http://www.new4stroke.com/sily%20w%20cylindrze.pdf

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 ...

Nice video, and at the end you can see how fast it can turn,

So I continued to divide the hair into four...

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 ..


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.

https://en.wikipedia.org/wiki/Parallel_motion

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

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

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:

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 ...

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 ...




Andrew

[Feliks]

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 ..



Andrew

[Feliks]

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....
