union spares Ltd. supply Wartsila marine diesel engine parts piston rings

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.

Known today Wartsila is a provider of large-bore diesel engines for marine propulsion systems and power plant applications,and we supply diesel engine parts such as piston rings for the engine provided by Wartsila .
