🔍 Key Concepts

• Diesel engine surging (speed repeatedly rising and falling under steady load) • How the fuel delivery system affects engine speed stability • Mechanical problems that cause irregular fuel flow to the injectors

💭 Think About

• Which choice would cause fuel to be delivered in a jerky or inconsistent way instead of smooth, proportional to throttle setting? • Think about which option would MOST directly affect how evenly fuel reaches the cylinders on every cycle, rather than just reducing power overall. • Which problem could make the governor constantly "chase" the correct speed because the fuel setting is not responding smoothly?

✅ Before You Answer

• Identify which components directly control or meter fuel quantity to the cylinders (focus on governor, rack, and injection pump). • Eliminate options that mainly cause low power or hard starting rather than speed hunting or cycling. • Ask: which fault would make the fuel control move in small jumps or hang up, instead of adjusting smoothly with engine load?
