Piston Oil Control Ring

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.

Piston oil control ring.

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 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. Taper sided compression rings are utilised to control ring sticking problems in high output engines. 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. Improving heat transfer from the piston to the cylinder wall. Oil control piston rings designed and manufactured for diesel engine applications. The oil ring is also the primary stabilizing component of the ring pack.

For the oil rings take out the rings marked 3 which are the rails and flex vents. Then spiral the first rail into the groove below the spacer followed by the remaining rail into the groove above the spacer. Oil control rings and seals are used in light vehicle gasoline engines and truck diesel engines. They are available in single piece and spring energized configurations with a wide range of scraping land designs.

Oil control piston rings and seals are used in conjunction with other rings or as stand alone applications. The main functions of piston rings in engines are. The oil control ring if the top compression ring has the most difficult of tasks in the engine then at the other end of the piston ring pack the oil control ring doesn t have it much easier. Generally the second and third compression ring are taper faced and supplied to improve oil sealing.

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. Oil control rings can break if there is excessive piston to cylinder clearance allowing too much piston slap to occur. An oil control ring is fitted into the lower groove of the piston. It must not be fitted in grooves other than ones of the same section.

You will have twice as many rails as you have flex vents. The first step is to place the spacer in the groove.
