Cylinder liner for DAF

The cylinder liner, part number 159289, serves as the internal wall of the cylinder within the DAF engine block. It provides a dedicated surface for the piston and its rings to travel against during the engine cycle. By housing the piston, the liner facilitates the transfer of heat from the combustion process to the engine coolant circulating through the block. This component is essential for maintaining the necessary compression levels required for efficient engine operation and helps manage oil consumption by ensuring a consistent seal for the piston rings.

This component is engineered for specific DAF engine configurations. The actual manufacturer of this part is DAF. Cylinder liners are installed within the engine block to provide a replaceable wear surface, which protects the block itself from the direct friction and heat generated by the reciprocating motion of the pistons. By replacing the liner, maintenance technicians can restore the internal geometry of the cylinder, which is vital for the overall performance and longevity of the engine assembly.
