Cylinder liner for Scania

The cylinder liner, part number C71030, is a cylindrical component installed within the engine block. It serves as the internal surface for the piston and piston rings, protecting the engine block from the heat and friction produced during the combustion cycle. By acting as a replaceable interface, this component allows for the maintenance and refurbishment of the engine block without requiring a complete replacement of the block itself.

This component is engineered for Scania engines used in trucks, buses, and industrial machinery. It is designed to maintain proper cylinder compression and assist in oil control, which are necessary for the efficient operation of the engine. Proper installation of this liner is essential during engine overhauls to ensure that the piston assembly functions correctly.

Cylinder liners facilitate the sliding movement of the piston while containing the combustion gases within the cylinder. They are often used to manage thermal transfer and provide a consistent surface for lubrication, which helps maintain the seal between the piston rings and the cylinder wall. Replacing a worn or damaged liner helps restore engine performance and prevents further damage to the internal moving parts of the engine.
