Cylinder liner for Scania TD120

The cylinder liner is a cylindrical component that inserts into the engine block of the Scania TD120. It forms the inner wall of the combustion chamber and provides the sliding surface for the piston to travel during engine operation. By containing the combustion process, this component facilitates the transfer of heat from the piston and combustion gases to the engine cooling system while maintaining the seal necessary to preserve compression.

This part is compatible with the Scania TD120 engine. It is engineered to meet the specific dimensions and tolerances required for this power unit to ensure proper fitment within the engine block.

In internal combustion engines, the cylinder liner acts as a replaceable barrier between the piston and the engine block. This design allows for the restoration of the cylinder bore surface without needing to replace the entire engine block. Liners are critical for maintaining engine efficiency, managing thermal loads, and ensuring that the piston rings maintain a consistent seal against the cylinder wall throughout the power stroke.
