Cylinder liner for Scania TD71A

The cylinder liner, part number 89370110, acts as a sleeve inserted into the engine block of the Scania TD71A. It provides a precise sliding surface for the piston to travel against during the engine cycle. By housing the piston, this component protects the engine block from direct contact and wear resulting from the constant movement of the piston assembly. It also manages the internal pressures and temperatures generated during the combustion process, ensuring the integrity of the cylinder environment.

This component is compatible with the Scania TD71A engine found in various industrial cranes and heavy machinery. It is engineered to meet the specific dimensional requirements of this engine block to ensure a proper fit and seal. Maintaining the condition of the cylinder liner is necessary for preserving cylinder compression, which supports efficient combustion and overall engine output.

In internal combustion engines, cylinder liners serve as the primary interface for the piston rings. They are designed to contain the combustion gases and facilitate heat transfer from the piston to the cooling system. Proper installation and surface condition of the liner are critical for preventing oil consumption and maintaining consistent power delivery across the operating range of the machine.
