🔍 Key Concepts

• unit injector design and how fuel quantity is adjusted • difference between timing and metering in fuel injection • role of the rack, camshaft, and governor in a diesel fuel system

💭 Think About

• Which component can change position to vary how much the injector plunger’s effective stroke delivers, without changing when injection starts? • Which item mainly sets when the plunger moves versus which one sets how much fuel it delivers each stroke? • If engine speed doubles but that component’s setting stays the same, does the amount of fuel per stroke actually change?

✅ Before You Answer

• Identify which part is directly connected to the fuel control mechanism for each cylinder. • Separate injection timing (when injection happens) from fuel metering (how much is injected). • Verify which choice is adjusted by the governor and operator’s throttle control to regulate power output.
