Developments in Cylinder Liner Lubrication - Class 4 Ex

Cylinder lubrication is an accessory applied to facilitate the operation of a two-stroke crosshead diesel engine. Failure in operation may cause considerable damage and can render an engine inoperative. All four cylinder lubrication systems described and considered below are assumed capable of performing their

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.

Marine Lubrication Stem to Stern | 3 Engine Oils 2.1 Slow-speed diesel engines Slow-speed, two-stroke crosshead engines are the predominant marine propulsion engines, also in use for land-based power generation applications. Lubrication of crosshead engines is separated into cylinder and crankcase lubrication. 2.1.1 Cylinder lubrication

Cylinder Liner Lubrication of Marine Two Stroke Crosshead .

This article discusses the problems in cylinder lubrication today in two stroke crosshead marine diesel engines due to burning of lower quality, high sulfur, catalytically cracked residual fuels. Also the engine developments in the past few decades which have increased the power output per cylinder has made the conditions harsher for the lubricants.

marinediesels.co.uk The Two Stroke Crosshead Diesel Engine .

The most powerful diesel engines in the world are two stroke crosshead engines. Some of these engines have cylinder bores approaching 1metre with a stroke of over 2.5 metres. The crankshaft can weigh over 300 tons, with the engine weighing in excess of 2000 tons. Click here to see some more photos.
