Piston rings suitable for power plant- and marine diesel engines
MAN B&W - Hyundai Himsen - MaK - Wartsila
Piston rings have three important tasks:
- The compression rings seal the combustion chamber from the crank
space and thus prevent an increase in pressure (blow-by) in the crankcase.
- The piston rings transmit the during the combustion process formed
heat to the cylinder liner and thus support the necessary cooling of the
piston crown or the piston, respectively.
- The oil scraper ring controls the oil film on the running surface of the
cylinder liner, thus creating the optimal tribological conditions for trouble-
free engine operation.
Referring now to the highly dynamic, mechanical stresses to which the piston rings are exposed to during engine operation, so it is clear, that long-term experience and comprehensive technological knowledge is required for the development and production of these components.
Therefore, we rely solely on the expertise of German suppliers.
