Abstract
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
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 tribological system
“cylinder liner - piston ring - piston” of large bore slow speed
marine diesel engine to reduce friction problems in mentioned
system.
