Q

If a scavenging air space fire occurs on a slow-speed diesel engine and the engine is stopped, which of the following should be done to prevent distortion due to heat?

🔍 Key Concepts

• Scavenging air space on a slow-speed diesel and why the structure around it can overheat after a fire • What happens to a hot, heavy engine structure if it cools unevenly or is left with very high local temperatures • The purpose of a jacking gear and how slow turning affects temperature distribution in a large engine

💭 Think About

• Which option best helps distribute heat evenly through the engine components while the engine is stopped? • Which actions could make distortion more likely by exposing hot metal to cold air or by allowing one area to stay much hotter than the rest? • Think about what the jacking gear is normally used for and whether it can help in a situation involving localized overheating.

✅ Before You Answer

• Check which choice actively promotes even cooling of the engine structure. • Eliminate choices that would likely suddenly cool hot metal surfaces or leave a localized hot spot untouched. • Confirm which method aligns with standard slow-speed diesel engine practice for dealing with thermal stress and distortion after a scavenging air space fire.
