🔍 Key Concepts

• Full-flow vs. bypass lube oil filtration in diesel engines • How a high‑pressure supply gallery is fed in typical main bearing lubrication systems • Differences between shunt, bypass, batch, and centrifugal lube oil arrangements

💭 Think About

• Which type of system sends oil through the filter before it goes to the engine’s main oil gallery, rather than returning it to the sump? • For each option, ask: does the filter handle all of the pump output to the bearings, or only a portion that is cleaned and then sent somewhere else? • Think about which systems are mainly used for continuous inline filtration versus separate cleaning/conditioning of oil in the sump or a side stream.

✅ Before You Answer

• For each choice, decide whether the filtered oil goes to the bearings/high‑pressure gallery or back to the sump. • Identify which systems deal with oil in continuous service versus periodic cleaning (batch). • Make sure you can state, in one sentence, the flow path: pump → filter → ? for each option before picking an answer.
