🔍 Key Concepts

• Relationship between overspeed and safety/trip devices on diesel engines • How a governor controls engine speed versus how a fuel rack is positioned/latched** • What must be manually reset or repositioned before an engine will restart after an overspeed event

💭 Think About

• Think about what happens mechanically when a diesel engine overspeeds. Which component is designed specifically as a safety device to stop fuel flow in that situation? • After the overspeed event has stopped the engine, consider what condition would remain that would still prevent fuel injection even though you are cranking at normal speed. • Which of the choices describes a condition that is most likely to persist until someone takes a deliberate action, rather than damage that may or may not occur?

✅ Before You Answer

• Identify which options refer to a safety/trip mechanism versus normal governing action. • Ask yourself: which condition would leave the fuel rack locked or out of the injection position after the overspeed? • Verify which problem would prevent restart even if the governor and oil pressure are otherwise normal.
