🔍 Key Concepts

• difference between starting air and scavenge air on a diesel engine • what an overspeed trip does and when it activates • what a banjo oiler line is used for

💭 Think About

• If the engine is cranking at proper speed, what systems are already working correctly? • Which item in the choices is most directly related to why fuel will or will not be injected and burned when the engine is already turning? • When would an overspeed device normally trip: before the engine starts, during normal speed, or when speed is already too high?

✅ Before You Answer

• Confirm which system is responsible for getting the engine turning versus keeping it from firing • Think about whether scavenge air pressure exists before the engine is actually running • Recall that an overspeed trip usually prevents the engine from exceeding a safe RPM, not from initially cranking at normal starting RPM
