Cylinder liner for Scania

The cylinder liner 89175110 serves as the internal sleeve for the engine block, creating the chamber where the piston travels during operation. It maintains the seal required for compression within the combustion chamber and facilitates the transfer of heat from the piston to the cooling system of the engine. By providing a consistent surface for the piston rings, this component ensures the engine maintains its intended operating pressure and efficiency.

This part is compatible with various Scania engine configurations. It is engineered to match the specific bore dimensions and cooling requirements of the engine block. Proper installation of the liner is a standard procedure during engine overhaul to restore the internal geometry of the cylinder and ensure correct ring seating.

In heavy machinery and transport engines, cylinder liners are used to manage the friction and thermal loads generated by continuous operation. They protect the engine block from direct contact with the piston and rings, allowing for maintenance of the internal cylinder diameter over the service life of the power unit.
