In an auxiliary diesel engine "bypass type" lubricating oil system, what does the main lube oil pump do?

In an auxiliary diesel engine utilizing a bypass type lubricating oil system, the primary function of the main lube oil pump is to force some oil through a filter. This process is crucial for maintaining the cleanliness of the oil that circulates within the engine.

By sending oil through a filter, the system effectively removes contaminants and particles that could potentially harm engine components. This filtration process ensures that cleaner oil is delivered to the engine's vital parts, reducing wear and tear and enhancing overall performance. Bypass systems often allow a portion of the oil flow to be filtered while the remainder circulates directly within the engine, thereby ensuring efficient lubrication while maintaining oil pressure. This design also helps in prolonging the life of the lubricant and the engine itself.

Understanding this function highlights the importance of lubrication in engine operation, particularly how effective filtration contributes to engine longevity and reliability.
