Cylinder liner for DAF

The cylinder liner, part number 159288, acts as the internal sleeve within the engine block where the piston travels during the combustion cycle. This component provides a dedicated surface for the piston and rings to operate against, protecting the engine block from direct friction and the thermal loads generated during operation. It facilitates the transfer of heat from the combustion chamber to the engine cooling system, ensuring that the block remains within its intended operating temperature range.

This liner is compatible with DAF engine applications. It is engineered to maintain precise dimensions and surface finishes to ensure a proper seal with the piston rings, which supports engine compression and operational efficiency. The component is installed into the engine block to serve as the primary wear surface for the reciprocating piston assembly.

Cylinder liners are used in internal combustion engines to provide a replaceable wear surface for the piston. By maintaining a consistent internal diameter, the liner allows the piston rings to maintain a seal against the high pressures of the combustion process, preventing blow-by and maintaining power output throughout the engine service life.
