A piston ring is a split ring that fits into the grooves on the outer diameter of a piston in an internal combustion engine. Its primary function is to create a seal between the piston and cylinder wall, ensuring compression is maintained within the engine's cylinders during operation. Piston rings are essential for preventing leakage of gases or oil between the piston and cylinder wall. They also help to transfer heat from the piston to the cylinder walls, contributing to efficient cooling of the engine. In this context, piston rings play a crucial role in automotive engines, specifically within the oil pump system, where they aid in maintaining proper lubrication of engine components by controlling the flow of oil between the piston and cylinder wall.
