Cylinder liner for Scania TD103

The cylinder liner, part number 134970, acts as the internal sleeve for the combustion chamber in the Scania TD103 engine. It provides the sliding surface for the piston and piston rings, managing the thermal and mechanical stresses generated during the combustion cycle. By housing the piston movement, this component maintains the necessary compression levels required for consistent engine power and operational efficiency. It also assists in transferring heat from the combustion process to the engine cooling system, protecting the integrity of the engine block from direct wear.

This component is specifically engineered for the Scania TD103 engine model. It is designed to meet the precise dimensional requirements of this engine series to ensure a proper fit during assembly or engine overhaul. Proper installation of the liner is necessary to maintain the seal between the piston rings and the cylinder wall, which prevents blow-by and ensures that the engine operates within its intended design parameters.
