Cylinder liner for Scania TD103

The cylinder liner, part number 479380, functions as the internal wall of the cylinder within the Scania TD103 engine. It provides a precise surface for the piston to travel against while maintaining the necessary compression for the combustion process. By acting as a barrier between the piston assembly and the engine block, it facilitates heat dissipation and prevents direct wear on the block itself. The interior surface of this component is machined to ensure a seal with the piston rings, which helps manage oil consumption and prevents gas leakage during operation.

This component is compatible with the Scania TD103 engine model. It is designed to meet the specific dimensional requirements of this engine block to ensure proper fitment and alignment during installation. Maintaining the integrity of the cylinder liner is necessary for engine performance, as worn or damaged liners can lead to a loss of compression and reduced power output.

In internal combustion engines, the cylinder liner provides a replaceable wear surface that can be serviced when the engine block itself does not require replacement. It must withstand the thermal and mechanical stresses generated during the combustion cycle while maintaining its geometric shape to support the movement of the piston and rings.
