🔍 Key Concepts

• Lubricating oil system components in a diesel engine (pump, relief valve, filters, coolers, bearings) • Difference between pressure-regulating devices and things that just cause a pressure drop • Normal location and function of a pressure relief or bypass device in an engine lube system

💭 Think About

• Which component in a lube oil system is specifically designed to keep pressure from going too high, regardless of downstream restrictions? • Do filters and orifices actively control pressure, or do they just create resistance to flow that results in some pressure loss? • Think about what protects the system and bearings if the oil is cold and thick and the pump is trying to deliver too much pressure.

✅ Before You Answer

• Identify which choice is an active pressure-controlling device, not just a passive restriction. • Consider which component is normally adjustable or spring-loaded to open at a set pressure. • Eliminate any options that only describe flow restriction or filtration, not true pressure regulation.
