Cylinder liner for Scania DS94

The cylinder liner with part number 64034580 is a component for the Scania DS94 engine. This cylindrical part installs into the engine block to provide the internal surface for the piston to slide against during operation. It serves as a replaceable interface between the moving piston and the engine block, managing the friction and heat generated during the combustion process. By maintaining the integrity of the cylinder wall, the liner helps preserve the compression levels necessary for engine efficiency and power output.

This component is compatible with the Scania DS94 engine model. It is designed to be seated within the engine block to facilitate heat transfer away from the combustion chamber and to maintain the geometry of the cylinder bore. Proper installation of the liner is a standard procedure during engine overhauls to restore the sealing surface and ensure the engine block remains protected from direct wear.

Cylinder liners function as the primary wear surface in internal combustion engines. They allow for the restoration of the cylinder bore without requiring the replacement of the entire engine block. By providing a controlled environment for the piston rings, liners assist in maintaining oil film thickness and gas sealing, which are necessary for the operation of heavy-duty machinery engines.
