The oil control rings regulate engine oil consumption. They scrape the excess oil on the cylinder walls back to the sump through the gaps in the piston ring and the holes in the piston while retaining a very thin layer of oil from friction-free running of piston rings inside the cylinder.

Remove wear ridge on cylinder walls before removing pistons. Failure to do this may lead to cracked or broken piston ring lands. Use a good ridge cutter to do this. Remove glaze of the cylinder bores by light honing or by a glaze breaker. Thoroughly clean the cylinder walls to remove all grit and carbon and smear them with light engine oil. Check the size of the cylinder bores and correctly choose the size of rings for trouble-free performance. Piston Rings are available from standard size to different oversizes for all engines. Chromium plated piston rings must not be used in chromium plated cylinder liners.

This is the most common and simple joint among all types of piston ring joints. The cut is made at an angle to create higher resistance to leakage of the combustion gases.

The compression rings prevent leakage of gases in a combustion engine or leakage of pneumatic.hydraulic pressure in compressors hydraulic applications.

This has an asymmetrical change in the cross section which causes the ring to twist slightly inwards when installed and brings the bottom edge into contact with the cylinder wall, producing better sealing effects. This is a compression ring with a rectangular cross section and its geometrically simple form provides an adequate seal under normal operating conditions.

Piston rings for hydraulic applications are many times made of sintered material for improved wear resistance and anti-friction properties esp. in dry condition.Piston rings can me made of other special materials also to suit the special application conditions.

This has two contact lands which are narrow and thus a high unit pressure is achieved to control the oil lubrication. This has outside edges of both lands chamfered in the opposite direction to improve the oil scraping effect.
