Hi Jakobnev
I know the conrod doesn't cause the problems, but I think it can solve the problems. The problems is caused in the combustion chamber above piston. The problem is caused by sudden combustion causing an impulse, this impulse is the sudden high pressures and temperatures. The conrod mod is to smooth the impulse and convert it into useful work.

See an example here

The resulting waveform with the modification will probably look something like the attached scan. The area of the graph above the spring pressure will be delayed and added where it is more useful to generate output work. Remember that all the pressure and heat at TDC does nothing for usefull work, it only heats combustion chamber walls and cooling fluid. The real work is only transferred to the wheels after TDC.
