🔍 Key Concepts

• Function of the scavenging space in a slow-speed diesel engine • Typical causes of scavenging fires (sources of fuel and ignition) • Standard engine-room prevention practices for avoiding fires in air and gas passages

💭 Think About

• Which option actually reduces or removes the fuel source for a scavenging fire, rather than just responding to a different problem? • Which choice relates specifically to conditions inside the scavenging space, not in the crankcase or bearings? • Ask yourself: is preventing air entry realistic for a running diesel engine that depends on air for combustion?

✅ Before You Answer

• Identify which choice directly addresses cleanliness and oil accumulation in the scavenging space. • Separate measures related to crankcase explosions from those related to scavenging fires. • Verify which option is a preventive measure rather than an emergency response or unrelated monitoring task.
