PISTON RING Meaning and
Definition
-
A piston ring is a critical component of an internal combustion engine that is designed to seal the gap between the cylinder wall and the piston in order to prevent the leakage of combustion gases and to ensure efficient engine performance. It is a circular ring made of resilient materials, such as cast iron or steel, that is placed in grooves on the outer surface of the piston.
The main function of the piston ring is to create a reliable seal between the piston and the cylinder wall, thereby separating the combustion chamber from the crankcase and preventing the escape of gases and oil. It achieves this by exerting pressure against the cylinder wall to maintain a tight fit without causing excessive friction.
Piston rings are usually in sets, consisting of two or three separate rings, positioned above each other on the piston. The top ring, known as the compression ring, is responsible for sealing the combustion chamber against any gas leakage, while the second and third rings, known as oil control rings, are responsible for regulating the amount of oil on the cylinder wall and preventing its entry into the combustion chamber.
Due to the tremendous heat and pressure involved in the combustion process, piston rings are subject to wear and tear. Regular maintenance and replacement are therefore necessary to ensure optimum engine performance and to avoid potential issues such as decreased power output, increased oil consumption, and loss of compression.

Etymology of PISTON RING
The word "piston ring" has a straightforward etymology, with each component contributing to its meaning:
1. Piston: The word "piston" is derived from the Old French word "pistoun", which originally referred to the pestle of a mortar used in grinding. It can be traced back to the Latin word "pinsere", meaning "to pound" or "to beat". Over time, "pistoun" evolved into "piston", which came to specifically refer to the moving component in a cylinder engine.
2. Ring: The word "ring" is derived from the Old English word "hring", which can be traced back to the Germanic word "hringaz". Its original meaning referred to a circular band, typically made of metal or other materials, worn as an ornament or used for various purposes.
