🔍 Key Concepts

• Diesel engine cooling and lubrication behavior when changing from full power to stop • What happens to engine temperatures (pistons, valves, turbocharger) right after heavy load is removed • Difference between preventing overheating/damage versus cleaning or auxiliary functions (like stack, boiler)

💭 Think About

• Think about what parts of the diesel engine are still very hot right after operating at high load and what idling does to those temperatures. • Ask yourself: which choice deals directly with protecting the engine itself, rather than other attached systems or side effects? • Consider which option would still be important even if there were no exhaust stack or waste heat boiler connected.

✅ Before You Answer

• Which option is about internal engine protection rather than external equipment? • Which function of idling is related to allowing cooling and oil circulation before fuel is shut off? • Eliminate any answers that depend on equipment you might not always have (like a waste heat boiler).
