Increasing the energy efficiency of the marine propulsion systems currently represents one of the priorities that have been placed in front of all subjects of maritime shipping market. More and more ship owners aspired to larger and more powerful diesel engines demanded from the marine engine manufacturers to implement various technological modifications to increase the engine efficiency, extend the life of engine components, and thus prolonge regular overhauling period of them. One of the way

The aim of this paper is to present structural modification of tribological system "cylinder liner - piston ring - piston" of large bore slow speed marine diesel engine to reduce friction problems in mentioned system.
