Abstract
As marine diesel engine output increases, the combustion chamber will be put under ever much strain. Recently, the contamination of Bunker Fuel Oil by FCC has seriously damaged moving parts and wear and tear of them have reportedly affected the safe navigation of ships. In order to know the wear and tear of moving parts within the combustion chamber, inspection and maintenance are carried out at anchor; if wear and tear could be studied on board at sea, such data could improve engine operation and help to prevent engine troubles. Let us introduce the skill of continuous monitoring and analysis of cylinder oil drain from large-output marine diesel engines. Consequently, a reduction in the amount of cylinder oil used will contribute to cutting costs.
