Cylinder liner for Scania MD70B

The cylinder liner with part number 88469110 functions as a cylindrical insert within the engine block of the Scania MD70B. It provides the necessary surface for the piston and its rings to move during the combustion cycle. By acting as a barrier between the piston assembly and the engine block, it manages the heat and friction generated during operation while maintaining the integrity of the combustion chamber.

This component is compatible with the Scania MD70B engine. The liner is engineered to meet the specific dimensional requirements of this engine block to ensure proper fitment and alignment. It is manufactured by Scania to align with the original specifications for this engine series.

Cylinder liners serve as the primary contact surface for piston rings in internal combustion engines. They are designed to maintain a seal that preserves compression and controls oil consumption. When the internal surface of the liner wears down, it can lead to a loss of engine efficiency and increased oil bypass. Replacing the liner allows for the restoration of the cylinder wall surface, which is standard practice during engine overhauls to maintain operational performance.
