Regarding a diesel engine crankcase, the general arrangement and installation should preclude the possibility of __________.
• Crankcase explosion prevention on diesel engines • Role of ventilation and sealing in the crankcase • How oil mist, air, and ignition sources can create a dangerous condition
• Which situation inside a crankcase could lead to an explosion or fire if not properly controlled? • Think about what the main safety concern is in crankcase design: is it more about air, water, oil leakage, or temperature? • Which choice describes a condition that designers most want to avoid because it could create an ignitable mixture?
• Identify which option directly relates to forming a flammable or explosive mixture in the crankcase • Ask: which choice would engine designers most urgently prevent from a safety standpoint, not just cleanliness or maintenance convenience? • Verify which condition would be specifically addressed in crankcase ventilation and relief system design guidance
