When steel is used in the construction of piston rings, it is usually with the ____________.

The use of steel in the construction of piston rings is primarily associated with the oil control ring. This is because steel offers excellent wear resistance and durability, which are essential qualities for the oil control ring as it plays a crucial role in regulating the engine's oil consumption. The oil control ring helps prevent excess oil from entering the combustion chamber, thus minimizing oil burning and ensuring efficient engine operation.

The choice of material for piston rings is important; while compression and sealing rings are typically made from cast iron or other materials that provide good sealing properties, the robust nature of steel allows for enhanced performance and longevity in the oil control ring. This makes steel an ideal option for managing the lubrication system within an engine, leading to better performance and a longer lifespan of engine components.
