Piston rings for power plant- and marine diesel engines

MAN B&W - Hyundai Himsen - MaK - Wartsila


The piston ring is a rather unimpressive acting component. However, no engine would work without him....

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.
