🔍 Key Concepts

• Basic layout of a jerk-type fuel injection pump (which parts move vs. which are fixed) • Difference between a plunger and a barrel/sleeve in an inline fuel pump • How the control rack interacts with the plunger to change fuel quantity

💭 Think About

• Look at which part the label N is pointing to: is it the central moving shaft, the outer fixed bore, or the toothed bar on the right? • Trace how fuel would be pressurized: which part actually slides up and down to pump fuel, and which part simply forms the close‑fitting cylinder that it moves inside? • Find the gear teeth: which component do they turn, and which option name matches that side‑to‑side toothed piece?

✅ Before You Answer

• Identify the toothed horizontal bar first and match it with one of the answer choices (then you can eliminate that choice for N). • Decide whether N is the inner moving member or the outer cylindrical housing/bore around it. • Recall that in pump terminology, plunger = moving piston and barrel/sleeve = closely fitted stationary cylinder and match that to what N is pointing at in the illustration.
