🔍 Key Concepts

• Crankcase explosions in large diesel engines • Conditions that create an oil mist inside the crankcase • Early warning devices used to prevent bearing failures and fires

💭 Think About

• Which part of the engine does an oil mist detector monitor, and what dangerous condition can develop there? • What engine problem would produce very fine oil droplets (mist) due to high local temperatures? • Which of the answer choices would most directly lead to a fire or explosion risk inside the crankcase?

✅ Before You Answer

• Focus on problems that occur inside the crankcase area, not in external systems • Ask which condition would cause localized overheating of metal parts in contact with lube oil • Eliminate options that do not naturally produce an oil vapor/mist hazard
