🔍 Key Concepts

• Relationship between cam/tappet stroke and the plunger’s actual up‑and‑down travel • How the control rack and gear segment change fuel quantity by rotating the plunger helix, not by changing cam lift • How injection is ended in a jerk‑type fuel pump (spill port aligning with the helix)

💭 Think About

• Look at what part "A" physically contacts as the pump operates. Does that contact change with rack setting, or is it fixed for every stroke? • Ask yourself: in this design, what feature actually determines when injection stops – a flange at the bottom of the plunger, or the position of the helix relative to the spill port? • Consider whether the component at "A" would need to rotate with the plunger, or stay fixed, for its function. How does that affect which of the options can be true?

✅ Before You Answer

• Identify which component sets plunger stroke (cam/tappet travel vs. any stop or flange). • Trace how the rack (right side) and gear (E) interact with the plunger: what motion do they transmit? • Decide whether the function described in each option would require controlling rotation or controlling vertical travel of the plunger, then match that to what a flange in that location can realistically do.
