Cylinder liner for Scania D7A/ B

The cylinder liner, part number 2711596, serves as a fundamental component for Scania D7A and D7B series engines. It is installed into the engine block to form the internal wall of the combustion chamber, providing a controlled surface for the piston to travel during the combustion cycle. This component maintains the structural integrity of the cylinder bore while facilitating heat transfer from the combustion process to the engine cooling system.

This specific part is engineered for compatibility with Scania D7A and D7B engine configurations. It is designed to meet the dimensional requirements of these engine blocks, ensuring proper seating and sealing within the crankcase. By providing a consistent bore diameter, it supports the function of the piston rings in maintaining compression and managing oil control.

Cylinder liners are used in internal combustion engines to create a replaceable wear surface for the piston assembly. By housing the piston and rings, the liner protects the engine block from direct contact with combustion gases and mechanical friction. Proper fitment of the liner is necessary to ensure the engine maintains its intended compression ratios and operational efficiency throughout its service life.
