🔍 Key Concepts

• Crankcase explosions usually start with an internal ignition source plus an oil mist or vapor fuel source • Think about what component inside the crankcase can get hot enough to ignite oil mist • Distinguish between conditions in the scavenge air space, cooling water system, and inside the crankcase

💭 Think About

• Which option directly creates a local ‘hot spot’ or ignition source inside the crankcase itself? • Which options mainly affect areas outside the crankcase or would be more of a contributing/indirect factor rather than the immediate trigger? • For each choice, picture where the condition occurs and whether it can ignite oil mist in the crankcase volume.

✅ Before You Answer

• Verify which choice is located inside the crankcase and can overheat locally • Check which condition is best known in marine engineering texts as the primary ignition source for crankcase explosions • Eliminate options that mainly describe problems in the cooling water system or air supply system rather than inside the crankcase
