Cylinder liner for DAF DA475

The DNT620/N cylinder liner acts as a replaceable sleeve inserted into the engine block to provide a sliding surface for the piston. It contains the combustion process and guides the piston movement, ensuring a seal that maintains the necessary compression for engine operation. This component also facilitates the transfer of heat from the piston and combustion gases to the engine cooling system to help maintain stable operating temperatures.

This part is compatible with the DAF DA475 engine. The inner surface is machined to provide an interface with the piston rings, which assists in managing friction and oil consumption during the engine cycle.

Cylinder liners are used in internal combustion engines to form the cylinder wall. By providing a renewable surface, they allow for the restoration of engine tolerances without requiring the replacement of the entire engine block. They are engineered to withstand the pressures and thermal loads inherent in the operation of heavy machinery engines.
