🔍 Key Concepts

• Bypass lubrication system versus full-flow filtration in diesel engines • Where oil pressure and temperature are most suitable for feeding a centrifuge • Effect of taking oil from suction, discharge, sump, or header on engine lubrication and centrifuge performance

💭 Think About

• In a bypass system, is the centrifuge cleaning all the oil going to the bearings, or just a small side stream? How does that affect where you tap the line? • At which location will the oil have enough pressure and flow for the centrifuge to work properly without starving the engine of lubrication? • Think about where you would want to return the cleaned oil and work backward: from what point in the system would it be most logical to take the dirty oil?

✅ Before You Answer

• Identify which points in the system are under positive pressure and which are under suction or static in the sump. • Decide at which point the oil is already pumped and warmed, but removing a small portion will not reduce supply to the bearings. • Confirm which connection point matches the definition of a bypass (side-stream) filter, not the main full-flow path.
