Lubrication is perhaps the most important single factor in the successful operation of diesel engines. Consequently, too much emphasis cannot be placed upon the importance of the lubricating oil system and lubrication in general. It is not only important that the proper type of oil be used, but it must be supplied to the engine in the proper quantities, at the proper temperature, and provisions must be made to remove any impurities as they enter the system otherwise it can ruin ship main engine.

To understand ship‘s lubricating oil system Ship‘s lubricating oil system function and parts, Importance of good lubrication oil in main engine.

The lubrication system of ship provides a supply of lubricating oil to the various moving parts in the ship‘s engine. Lubricating oil in a diesel engine is used for the following purposes: 1. To prevent metal-to-metal contact between moving parts. 2. To aid in engine cooling. 3. To form a seal between the piston rings and the cylinder wall. 4. To aid in keeping the inside of cylinder walls free of sludge and lacquer.
