What Is the Purpose of Piston Rings? The main role of piston rings in cars is to regulate the amount of oil cars consume. Piston rings form seals around combustion chambers, which allows them to transfer heat to cylinder walls.

en.wikipedia.org/wiki/Piston_ring

A piston ring is a split ring that fits into a groove on the outer diameter of a piston in a reciprocating engine such as an internal combustion engine or steam engine.. The main functions of piston rings in reciprocating engines are: Sealing the combustion chamber so that there is minimal loss of gases to the crank case.

# Purpose of Piston ring: If there is a large clearance between the piston and the cylinder wall, the piston wobbles as it executes a reciprocating motion. In other words the motion of the piston won't be exactly vertical, it will also have some undesirable side ward motion.

Piston rings transfer heat from the piston crown to the cylinder. When gas ignition takes place, the temperature inside a piston reaches approximately 300 C. If heat accumulates inside the piston, the engine may be damaged. For that reason, it is necessary to release the heat build-up. Piston rings help release this heat.

en.wikipedia.org/wiki/Piston

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms.It is the moving component that is contained by a cylinder and is made gas-tight by piston rings.In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod.

Piston and Piston Rings. A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process.The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head.

The Piston Rings seals off the gap between the cylinder walls and the piston. This is why the fluids on both ends of the piston head do not mix. This is the same reason why if the piston rings are damaged, then your engine oil will start mixing with the combustion mixture and end up in a smoky exhaust.
