Cylinder liner for Scania TID61

The cylinder liner, part number 89352110, acts as the primary sliding surface for the piston as it travels within the engine block of the Scania TID61. It is positioned inside the cylinder bore to manage the internal environment where combustion occurs, providing a stable interface for the piston rings to maintain compression and control oil consumption. By housing the piston movement, this component helps manage the thermal transfer from the combustion chamber to the engine cooling system.

This component is specifically engineered for fitment in the Scania TID61 engine. It functions as a replaceable wall for the cylinder, allowing for the restoration of the bore surface without requiring the replacement of the entire engine block. The liner is manufactured to precise tolerances to ensure a secure fit within the engine crankcase and to maintain the necessary clearances for reciprocating parts.

In heavy-duty diesel engines, cylinder liners provide a controlled surface that withstands the mechanical and thermal stresses of the power stroke. They are critical for maintaining the seal between the combustion chamber and the crankcase, which is necessary for efficient engine operation and consistent power output.
