Cylinder liner for Scania DS/D

The cylinder liner with part number 14-458190-00 serves as the internal sleeve for the engine block in Scania DS/D series engines. It creates the cylindrical path for the piston to travel during the combustion cycle, ensuring that the force generated by the ignition is effectively transferred to the crankshaft. This component also aids in the management of heat transfer from the combustion chamber to the cooling system, which helps maintain stable operating temperatures within the engine assembly.

This component is compatible with Scania DS/D engine models. It is designed to meet the dimensional requirements of the engine block to ensure a precise fit and proper sealing of the combustion chamber. Maintaining the correct surface finish and dimensions is necessary for effective piston ring sealing and oil film retention.

Cylinder liners function as the replaceable wear surface inside an engine block. By containing the combustion pressure and providing a controlled environment for the piston and rings, they protect the main engine block from direct friction and thermal stress. Proper installation ensures that the engine maintains the compression ratios required for consistent power output and efficient operation.
