When a fuel injection nozzle overheats, which of the problems listed can be expected?

🔍 Key Concepts

• Fuel injection nozzle function in a diesel engine • Effects of overheating metal parts on precision components • How fuel is metered and atomized through an injector

💭 Think About

• Think about what a fuel injection nozzle actually does in normal operation. What changes if its tip gets too hot? • Which option describes a gradual performance problem rather than an immediate catastrophic failure? • How would overheating affect the nozzle’s ability to control fuel flow and spray pattern?

✅ Before You Answer

• Identify which options are sudden, extreme events (like an explosion or a cracked head) versus control/precision issues. • Consider which component is directly affected: is the problem happening inside the nozzle or elsewhere in the engine? • Ask yourself: does overheating a nozzle more likely change how much and how well fuel is delivered, or does it instantly destroy major engine parts?
