🔍 Key Concepts

• Crankcase explosions in diesel engines usually involve oil mist and an ignition source inside the crankcase • How crankcase ventilation, leakage, or vacuum affect the buildup or removal of oil vapors • Why proper crankcase vacuum is a safety measure on large marine diesels

💭 Think About

• Which option would make it easier for oil mist and vapors to accumulate inside the crankcase instead of being safely removed? • Think about whether each choice would increase or decrease the chances of an oil mist cloud igniting inside the crankcase. • Which condition represents a loss of crankcase integrity or control, rather than a normal or protective operating condition?

✅ Before You Answer

• Identify which options describe normal safety practices (proper vacuum, safe venting) versus abnormal conditions. • Ask: Does this condition contain vapors safely, remove vapors safely, or let them escape or leak in an uncontrolled way? • Consider which choice is most likely to allow hot spots or backfiring flame to reach oil vapors in or near the crankcase.
