Piston rings are circular metal rings fitted around the circumference of the piston.
They serve multiple functions:
*Sealing: Piston rings create a seal between the piston and the cylinder walls, preventing the combustion gases from leaking into the crankcase.
*Heat Transfer: They help transfer heat away from the piston to the cylinder walls, preventing overheating.
*Lubrication: Piston rings also help distribute engine oil along the cylinder walls for lubrication, reducing friction and wear.
Pistons and piston rings are integral components of internal combustion engines, contributing to their performance, efficiency, and longevity. By understanding their functions, types, and maintenance requirements, car enthusiasts and mechanics can keep their engines running smoothly for years to come.
