    Abstract : The Piston Ring - Cylinder Liner (PRCL) contact is the single largest contributor to frictional losses in an internal combustion (IC) engine, causing 20-40% of all mechanical losses. If these mechanical losses can be reduced by 10% then vehicle fuel efficiency could be increased by approximately 1.5-2.5%. READ MORE
