The cylinder liner with part number 3948095 acts as the internal wall of the engine block for the Cummins 6CTAA. It creates the sliding surface for the piston assembly and contains the combustion process within the engine cylinders. This component is engineered to maintain the necessary dimensional tolerances for proper piston ring sealing and heat transfer from the combustion chamber to the cooling system.
This liner is compatible with the Cummins 6CTAA engine platform. It serves as a replaceable sleeve that allows for the restoration of cylinder geometry during engine overhauls or rebuilds, ensuring the engine block maintains its structural integrity and compression specifications.
In internal combustion engines, cylinder liners are used to manage the friction between the piston rings and the cylinder wall. They provide a controlled environment for the piston to move while facilitating the transfer of thermal energy to the engine coolant, which is necessary for maintaining consistent engine operating temperatures and preventing premature component failure.
