Cylinder liner for Scania D9B

This component is a cylinder liner for the Scania D9B engine. It functions as the internal sleeve within the engine block, creating the chamber where the piston travels during the combustion cycle. The liner is engineered to maintain the necessary seal for combustion pressure and to facilitate the transfer of heat from the piston and combustion gases into the engine cooling system.

The part number 22104272 is specifically configured for fitment in Scania D9B engines. These engines are utilized in various heavy-duty applications, including transport trucks and industrial machinery. Maintaining the integrity of the cylinder liner is necessary for engine compression and overall combustion efficiency.

In internal combustion engines, cylinder liners serve as the primary contact surface for piston rings. They are designed to withstand the cyclic thermal and mechanical stresses generated during engine operation. By providing a controlled surface for the piston assembly, the liner helps manage oil consumption and protects the engine block from direct wear caused by the reciprocating motion of the piston.
