Cylinder liner for Scania D/D N/D

The cylinder liner 89366110 serves as the internal surface within the engine block where the piston travels during operation. It provides the necessary interface for the piston rings to maintain a seal, which is required to contain the pressure generated during the combustion cycle. By forming the wall of the combustion chamber, this component also facilitates the transfer of heat from the piston and combustion gases to the engine cooling system.

This part is compatible with Scania D/D N/D engines. It is engineered to meet specific dimensional tolerances to ensure proper fitment within the engine block and to maintain the required clearance for piston movement. Proper installation of the liner is necessary to support consistent compression levels and to manage the thermal loads experienced during engine operation.

In heavy-duty engines, cylinder liners are used to define the bore of the cylinder. They are often replaceable, allowing for the restoration of the cylinder wall surface without requiring the replacement of the entire engine block. The liner must maintain its geometry under the thermal and mechanical stresses of the engine to ensure efficient operation and to prevent gas or oil leakage between the combustion chamber and the crankcase.
