Cylinder liner for Mercedes-Benz

The cylinder liner, identified by part number 89389110, serves as the internal sleeve for the engine block in Mercedes-Benz diesel power units. It creates a controlled environment for the piston assembly, facilitating reciprocating motion while maintaining the necessary seal for combustion pressure. By providing a consistent bore surface, this component supports the interaction between the piston rings and the engine block, which is necessary for efficient power generation and oil control within the cylinder assembly.

This component is engineered for specific Mercedes-Benz diesel engine configurations found in various heavy-duty applications. It is manufactured to meet the dimensional requirements of the engine block to ensure proper fitment and heat transfer during operation. The liner maintains the structural integrity of the cylinder bore, allowing for the correct clearance between the piston and the wall to minimize friction and prevent gas leakage during the compression and power strokes of the engine cycle.
