Piston Ring Oil

The primary usage of the piston ring is to seal the chamber where the piston is moving which can be a combustion chamber of a 2 stroke or a 4 stroke engine marine engines have three or more types of rings fitted on the circumference of the piston.

Piston ring oil.

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. Compression ring the compression ring is the top or closest ring to combustion gases and is exposed to the greatest amount of chemical corrosion and the highest operating temperature. A steel napier second ring and industry leading cp 20 oil ring round out the package. Maintaining the proper quantity of the oil between.

Piston rings commonly used on small engines include the compression ring wiper ring and oil ring. The oil scraped off the cylinder wall moves into the slots in the back of the oil ring grooves in a piston and from there it returns to the oil pan. Piston ring has serviced the automotive aftermarket since 1953. The bottom oil ring is actually made up of three different rings two narrow rails and one expander.

We are a family owned and operated local company now in our third generation. Hastings offers piston rings for nearly any application worldwide from automotive and truck to agriculture industrial small engine as well as marine and high performance. A support rail was then necessary to provide a solid surface that the oil ring can rest without fear of bending into pin bore. Some rings of this type are installed with expander rings.

As you ll see in the photos this support rail must be installed correctly for optimum performance. In addition the second rings are reversed twist taper faced cast iron. At hastings we manufacture a bold and broad offering of piston rings one that spans thousands of applications for virtually any engine. The oil ring s main function is to control the amount of oil that makes it between the piston and bore which is necessary for lubrication and heat transfer purposes.

Improving heat transfer from the piston to the cylinder wall. Piston ring employs a team of knowledgeable parts professionals that focus on service and supply and partners with industry leading manufacturers. Sealing the combustion chamber so that there is minimal loss of gases to the crank case. For 1 5mm and 1 16 ring sets the top rings are positive twist ductile iron barrel faced plasma moly inlaid.

However the second ring also provides a bit of oil control. The expander spring increases the pressure of the ring on the cylinder wall which improves the oil scraping effect. Piston rings are manufactured and classified on the basis of function and usability. Hastings revolutionized oil control ring design with the invention of the hastings flex vent oil control ring and it is now the accepted standard in the industry.
