Cylinder liner for Cummins 6CT

The cylinder liner, identified by part number 3800328, serves as the internal wall of the cylinder where the piston travels. It functions as a replaceable wear surface for the piston and its rings, shielding the engine block from direct friction and heat generated during the combustion process. By maintaining a precise internal diameter, this component ensures the necessary seal for compression and efficient combustion within the engine.

This component is designed for use in Cummins 6CT and 6CTAA diesel engines, which are commonly found in various heavy machinery and industrial equipment. The internal surface is machined to a specific finish to facilitate proper lubrication and optimal seating of the piston rings, which helps manage oil consumption and supports consistent engine performance.

In internal combustion engines, cylinder liners are used to define the combustion chamber and provide a path for heat transfer from the piston to the cooling system. They allow for the restoration of the cylinder bore without requiring the replacement of the entire engine block. Proper installation and maintenance of the liner are necessary to prevent loss of compression and to maintain the operational integrity of the engine assembly.
