Cylinder liners are used in a wide range of applications, depending on the type of engine and its intended use:

Cars and motorcycles (usually dry or integrated liners for small engines).
Heavy-duty vehicles (wet liners for large engines such as trucks, buses, agricultural machinery, marine engines).
High-performance vehicles (composite liners for racing cars and sports vehicles).
Generators and stationary engines (long-lasting and durable liners).

In internal combustion engines, cylinder liners are a critical component that increases the engine's resistance to wear, temperature, and pressure, extending the engine's efficiency and life. Their functions include preventing wear, providing thermal management, providing sealing, and providing ease of maintenance. These parts, produced in different types according to the engine design and application, directly affect the performance of the engine and ensure reliable operation of the engine.
