Piston Ring Oil Control

Oil control rings and seals are used in light vehicle gasoline engines and truck diesel engines.

Piston ring oil control.

Unlike the others the tension of the oil ring is controlled by the radial thickness of both of the oil rails as well as the size of the gap in the expander ring. By manipulating the different. They are available in single piece and spring energized configurations with a wide range of scraping land designs. It must not be fitted in grooves other than ones of the same section.

Hastings is the pioneer of oil control ring technology. Generally the second and third compression ring are taper faced and supplied to improve oil sealing. 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.

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. It is an excellent motor ring or seal. Taper sided compression rings are utilised to control ring sticking problems in high output engines.

An oil control ring is fitted into the lower groove of the piston. Oil control piston rings and seals are used in conjunction with other rings or as stand alone applications.
