🔍 Key Concepts

• Diesel engine cool-down procedures • Effects of high temperature and load on turbochargers and pistons • Importance of gradual temperature change to prevent damage

💭 Think About

• What happens inside a heavily loaded diesel engine (turbo, exhaust valves, pistons) if you stop it instantly at high temperature? • Which option best allows the engine to cool and stabilize temperatures evenly before you secure it? • Among the choices, which one reduces stress on engine parts and lubricating oil, rather than increasing it just before shutdown?

✅ Before You Answer

• Identify which option involves removing or reducing load before shutdown. • Check which choice would avoid heat soak and coking of lubricating oil in hot parts (like turbocharger bearings). • Eliminate any choice that suggests immediate shutdown under heavy load or adding load right before stopping.

Before shutting down the main propulsion engines on a fishing industry factory ship, ideally what should be accomplished FIRST?

The engine should be operated with the load removed from the engine for several minutes, then shut down.

The engine should be operated at rated load for several minutes, then shut down.

The engine should be operated at a steady, but substantial load for several minutes, then shut down.

The engine should be shut down immediately with no delay period, regardless of the engine load.
