"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. :wave:
