Which of the listed conditions could result in the failure of an auxiliary diesel engine to stop running when a normal shutdown is attempted?

🔍 Key Concepts

• How diesel engines shut down under normal conditions (fuel cut-off vs. air cut-off) • What happens when lube oil or other combustible fluids get into the intake air stream of a diesel engine • The role of overspeed/ emergency trip devices versus normal shutdown systems

💭 Think About

• Think about which option could provide an uncontrolled fuel source to the engine, even after the normal fuel shutoff has been operated • Ask yourself: which choice describes something that could let the engine keep getting energy to run, despite the fuel racks being at zero? • Consider which choices are more likely to affect how the engine runs (efficiency, temperature, pressure) rather than whether it can be stopped at all

✅ Before You Answer

• Identify which options relate to combustion air/fuel supply versus those that mainly affect engine performance • Decide which condition could effectively act as a substitute fuel entering with the intake air • Confirm which item is associated with normal running or protection systems rather than emergency overspeed shutdown only
