Q

When starting an auxiliary diesel engine in preparation for operation, what parameter must be checked FIRST upon start-up to avoid immediate engine damage?

🔍 Key Concepts

• Engine start-up sequence for diesel auxiliary engines • Purpose of lubricating oil versus fuel oil and cooling water • Which loss or failure would cause the fastest, most serious mechanical damage immediately after start

💭 Think About

• Right at the moment of start, which system absolutely must be functioning to keep metal parts from contacting each other without protection? • Which of these pressures, if low or zero, would destroy the engine within seconds rather than minutes? • Which option is directly tied to protecting bearings, crankshaft, and camshaft from friction at the instant the engine begins to turn?

✅ Before You Answer

• Identify which choice is directly linked to bearing and moving-part protection • Consider which system damage would show up immediately versus after some delay • Verify which pressure is normally designed to be established before or instantly at start-up on marine diesels
