Cylinder liner for Scania D7C

The cylinder liner 101WN16 serves as the internal sleeve for the engine block, creating the chamber where the piston travels. It functions as the primary contact surface for the piston rings, ensuring a sealed environment for the combustion process while facilitating heat transfer from the cylinder walls to the cooling system.

This component is engineered for the Scania D7C engine model. The precision machining of the internal diameter is required to maintain proper clearance with the piston and rings, which is necessary to preserve engine compression and manage oil consumption during operation.

In internal combustion engines, cylinder liners are installed to provide a renewable wear surface for the piston assembly. By isolating the piston movement from the engine block casting, the liner allows for the restoration of cylinder geometry during engine overhauls without requiring the replacement of the entire block.
