1.	What is the function of the oil ring?(a) To allow charge to the crankcase(b) To increase friction(c) To reduce the frictional losses(d) To compress chargeI have been asked this question in my homework.The query is from IC Engine in portion Design of IC Engine Components of Automotive Engine Design
Answer» Right option is (C) To reduce the frictional losses To explain I would SAY: OIL RING is also known as Oil scrapper rings PLACED below compression rings, they provide proper lubrication of the cylinder liner and reduce frictional losses.
