🔍 Key Concepts

• Crankcase explosions in diesel engines and how they start • Role of lubricating oil mist/vapor and a hot spot as an ignition source • Difference between causes that create a hazardous condition versus normal operating conditions

💭 Think About

• Ask yourself: Which choice describes a situation that actually creates an ignitable mixture inside the crankcase, not just normal oil movement or contamination? • Think about what two things are needed for an explosion: fuel (oil mist/vapor) and an ignition source. Which option clearly leads to both? • Which options describe conditions that might be common or harmful, but do NOT directly and specifically describe how a crankcase explosion starts?

✅ Before You Answer

• Identify which option involves vaporized or misted lubricating oil inside the crankcase, not just liquid oil • Check which option clearly implies the presence of an ignition source (such as a hot spot or high temperature surface) within the crankcase • Eliminate any options that describe situations that are bad for the engine but do not directly form an explosive mixture in the crankcase
