Piston Oil Control Ring

Oil control rings can break if there is excessive piston to cylinder clearance allowing too much piston slap to occur.

Piston oil control ring. The skirt of the piston and indeed the cylinder wall itself can be damaged and this damage can in turn wipe out the oil control ring assembly. With the most comprehensive line of piston rings compression rings and oil rings in the world we have a piston ring for practically any application racing automotive heavy duty transportation agriculture industrial small engine and more. Generally the second and third compression ring are taper faced and supplied to improve oil sealing. They don t have to seal against the bottom land either since the oil ring is not a compression ring but rather a control mechanism that cools and lubricates the piston by collecting oil and distributing it evenly on the cylinder walls.

The oil ring is also the primary stabilizing component of the ring pack. The main functions of piston rings in engines are. You will have twice as many rails as you have flex vents. Then spiral the first rail into the groove below the spacer followed by the remaining rail into the groove above the spacer.

Taper sided compression rings are utilised to control ring sticking problems in high output engines. Oil control piston rings and seals are used in conjunction with other rings or as stand alone applications. For the oil rings take out the rings marked 3 which are the rails and flex vents. An oil control ring is fitted into the lower groove of the piston.

Oil control rings and seals are used in light vehicle gasoline engines and truck diesel engines. The first step is to place the spacer in the groove. Oil control piston rings designed and manufactured for diesel engine applications. The main function of the ring in the bottom piston groove is to scrape oil from the cylinder wall meaning oil control rings play a major part in regulating an engine s oil consumption.

Sealing the combustion chamber so that there is minimal loss of gases to the crank case. Grover oil control piston rings and seals are designed for diesel engine applications. Maintaining the proper quantity of the oil between the piston and the cylinder wall regulating engine oil consumption by scraping oil from the cylinder walls. Our rings function in sets usually a top compression ring second groove compression or oil scraper ring and oil control ring and range from 1 125 to 8 875 bores.

It must not be fitted in grooves other than ones of the same section. A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine.
