STUDY OF THE WORKING SURFACE OF OIL SCRAPER RINGS AFTER APPLICATION OF POLYMERIC ADDITIVE "FORUM"
The mechanism of increase of operational characteristics of oil scraper rings, meaning that at back and forth motion of valves is not observed washing away of ultra disperse particles from a working surface of oil scraper rings for a long time that promotes elimination of a surface defects, increase in tightness of the given connection is presented.
