🔍 Key Concepts

• Injector rack function – it is the common control bar that changes the fuel delivery of the injectors simultaneously • Difference between injector rack, fuel injector body, and high‑pressure fuel line in a diesel engine • Location of the governor linkage and how it connects to the injector rack on a V‑type medium‑speed diesel (like in MO-0122)

💭 Think About

• On the illustration, which labeled part looks like a long bar or rod that could connect to multiple injectors, rather than a single small component like a nozzle or spring? • Trace from the governor/control linkage shown on the right side of the engine: which label marks the piece that this linkage would move to change fuel quantity to the injectors? • Compare the parts directly over each cylinder: which labels clearly point to the injector body itself or its nozzle, and which one points to the separate control rack beside it?

✅ Before You Answer

• Verify which label is on a linear bar or rod running along the injector(s), not on a line, spring, or plunger. • Make sure the chosen label is connected (visually or logically) to the fuel control/governor linkage, since that must move the injector rack. • Eliminate any label that is clearly pointing to a fuel line or the injector nozzle rather than the control rack.
