🔍 Key Concepts

• Diesel engine runaway conditions and why they can keep running without normal fuel injection • Difference between stopping fuel flow vs. stopping air supply on a diesel that is burning lube oil or vapor as fuel • Safety risks (explosion, catastrophic failure) if an overspeeding engine is not quickly starved of both fuel and/or air

💭 Think About

• If the engine is already burning lube oil drawn into the cylinders, will moving normal fuel controls immediately stop combustion? Why or why not? • Which action(s) directly affect what the engine actually needs to keep running: fuel from injectors, unintended oil fuel, and intake air supply? • In a real engine room emergency, what is the safest immediate way to starve a diesel that is self-fueling from oil mist or lube oil?

✅ Before You Answer

• Check which choices only affect injected fuel versus which affect intake air as well. • Verify which option would still allow the engine to run on lube oil alone if air is available. • Ask yourself: in a true runaway, which control can you realistically reach and use fast enough to avoid mechanical failure?
