Structural Modifications for Improving the Tribological Properties of the Cylinder Unit in Two-stroke Slow Speed Marine Diesel Engines

Increasing the energy efficiency of marine propulsion systems currently represents one of the priorities in the maritime shipping market. Ship owners aspiring to larger and more powerful diesel engines demand that the marine engine manufacturers implement various technological modifications to increase engine efficiency, extend the life of engine components, and prolong the regular overhauling period. One of the ways to meet these demands, among other things, is to improve the tribological characteristics of engine components. The aim of this paper is to present structural modification of the tribological system “cylinder liner - piston ring - piston” of large bore slow speed marine diesel engines to reduce friction problems in the system.
