One way to improve oil economy, reduce emissions, extend life cycle of combustion engine is compensation of ovality and taper in cylinders. It is clearly that clearances in the combustion chamber first of all depend on oval and taper of cylinder. Cylinder/piston clearances promote to increase of piston grooves wear and can lead to serious damage of the piston and rings.
As for sleeved engines (engines with removable liners) there is developed new method reducing of ovality from 150 to 15-20 micrometers. Developed method allows to return the cylinder/ piston clearances to original specification.
With it all cylinder sleeves remain in its original position inside engine and entire procedure takes 5 minutes per cylinder. This method allows to use old piston.
This method had been developed on the basis of similarity characters of ovality cylinder and ovality of proper circular liner compressed by two diametric opposite forces enclosed to the top of it.
So developed method allows correct cylinder deformation during life cycle of engine.
After applying of our method the oil consumption, guantity of blow-by combustion gases and guantity of toxic harmful exhaust droop approximately by 35%

I think you may be on to something there...then again...hmmmm. Would you mind running through that again, more slowly this time?

Golant, So, we finally hear from Novosibirsk! What you describe is very interesting, however, if I have to bring my motor to Novisibirsk, I guess I'll have to wait till this technology arrives in the U.S. (I would have tried to answer in Russian, but I can't figure out how to get my Cyrillic font to work...)
