Cylinder liner for DAF 105

The cylinder liner, part number 89861110, serves as a replaceable internal sleeve within the engine block of the DAF 105. It creates the chamber where the piston travels, maintaining the necessary compression for the combustion process while facilitating heat transfer from the piston assembly to the engine cooling system. By acting as the primary contact surface for the piston and its rings, the liner protects the engine block from direct friction and wear during operation.

This component is engineered specifically for the DAF 105 series engine. It ensures a correct fit within the cylinder bore, which is essential for maintaining proper oil film distribution and preventing gas leakage past the piston rings. Proper installation of this liner is necessary to preserve the integrity of the combustion chamber and to support the overall efficiency of the engine assembly.

In heavy-duty diesel engines, cylinder liners are used to manage the intense pressures and thermal loads generated during the power stroke. They allow for the restoration of cylinder geometry during engine overhauls without requiring the replacement of the entire engine block, providing a practical solution for maintaining engine performance over the service life of the machine.
