Cylinder Lubrication System for Diesel Engines | S

Large 2-stroke crosshead diesel engines (bore diameter 350 - 960 mm) on container vessels, oil & gas tankers and bulk carriers require huge amounts of lubricating oil, resulting in high operating costs and emissions. To meet this challenge, SKF has developed the fully electronically controlled SKF Cylinder Lubrication System CLU 4 and CLU5. The guide feed rate for large two-stroke diesel ...

Crosshead - Wikiped

The large two-stroke marine diesel engines are usually of this pattern. A crosshead is essential in a double-acting diesel engine (see also: H-class battleships: 12 MAN double-acting 2-stroke 9-cylinder diesels). Large diesels often have a plunger oilpump directly attached to the crosshead to supply oil under high pressure to the crosshead bearing.
