Most interesting Andrew but you won't find the answer to my question in the workshop manual, you will only find it by experiences caused by working on this type of engine.

It was, as I said a very common occurrence caused solely by not decoking the engine.
The excessive backpressure, as shown by the gauge on the control panel clearly showed the fault.
The bar magnet was used to get the broken part of the engine out, when ground correctly this part, being made of carbon steel would make an excellent addition to your tool box.
A crosscut chisel f.o.c.
That crank, sure it's not a wrist watch crank?
Think about the back pressure load on parts caused by excessive carbon build up on two strokes. Qoute./

Yes Merlyn, you do not even know how much I appreciate your remarks. because I know that I will not find them in the workshop manual ... It's good that you want to work with me with your experience. As you know, I do not have too much, because I had to find these codes in music .. That's why your help is great .. I now add my cody and maybe something good will be ...
You have noticed the excessive accumulation of carbon. Now that we have a new type of engine Feliks Commer, where there is no classic crankshaft, only pins with a diameter of 30 mm, we can approach the issue in a different way, as it was so far. These small plates do not need such lubrication as large crankshaft bearings, besides they do not even turn round, and do semi-turn .., so the lubrication can be a little smaller .. I do not know if you remember that two-stroke engines for motorcycles, are lubricated only with oil in the fuel and in a ratio of 1: 50. And these engines, completely protruding .. so I thought that my Felix Commer can be lubricated with normal diesel fuel, also with the addition of this oil, let's also say 1; 50 as we will take into account that diesel fuel already has good lubrication in the sona .. Imone would be poured into the engine instead of lubricating oil. Well, when 10 liters of such fuel are needed for lubrication, the amount of oil added would be 0.2 liters .. No and I think that this quantity would not plug the windows, because the rest would be the same as the main fuel, it would be fired without coke .. And I think that this should solve the problem of this too nagar. Simply a new lubricant oil felix, i.e. diesel fuel plus 1:50 oil for two strokes ... .. poured into the engine, instead of lubricating oil ..
It would have such advantages that in the winter it would not be too dense, and in the summer too sparse ... ... and this price is not too high ..
So even with a large amount of "oil" you would not have to worry about ... because also coke would not be created ... because, from burning fuel, it does not arise ...
I just do not know what oil companies are doing ...
here, one bottle is enough to make 50 liters of "feliks oil"

And here the drift part of the watch, which I personally will do on an ordinary lathe. The material to do this crankshaft weighed 80 KG and the shaft lasts 4 KG. It lasted for a month ...


You know how you see the problems of crankshaft production, and that's why I know it's not a simple thing ...
Here are a few examples, however, that the crankshaft is not necessarily a successful construction .. and despite its thickness, sometimes it ends ... And I will ask if ever seen such a broken clutch shaft, despite the fact that it is much thinner than the crank

Here, such a connecting rod of my idea .. For a semi-rotary shaft, it can be such, because all forces act by pushing the connecting rod to the lever .. only incidentally it is possible to act detachment parts from each other, so its protection can be negligible .. During normal engine operation, piston it is only pressed against the lever all the time ..
However, the cooperating surfaces are relatively large, and the connecting rod weight is smaller .. Formy Feliks Commer ..

What is a "Feliks Roller"?

this is the roller between the levers ... I let it be named ... I do not have to be about a larger diameter than a clutch shaft .

it's just a diagram that does not have to have a crosshead, but only a normal short connecting rod.

Here the red line is marked by the piston path associated with the lever. At 90 degrees the pressure of the piston on the cylinder wall is equal to 0, and with the traditional system the maximum .. And then we have virtually full torque ..

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

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:
