🔍 Key Concepts

• Fuel system layout: Look at how the high‑pressure fuel is created and delivered to the injector in the illustration. • Location of the fuel pump vs. injector: Decide whether they are combined in one assembly or separated and connected by lines. • Air vs. solid injection: Notice whether any compressed air line is feeding the injector nozzle.

💭 Think About

• Trace the path of the fuel oil (usually marked or colored) from the supply line up to the cylinder head. Does it enter a common manifold, a separate pump, or directly into a combined pump/injector? • Look closely at the injector body on the head: is there any connection to an air manifold, or is it operated purely by mechanical motion from a cam/pushrod/rocker? • Ask yourself: Does the engine appear to have one high‑pressure pump serving many injectors, or is each cylinder’s pumping action built right into the injector itself?

✅ Before You Answer

• Verify where the cam-driven plunger that creates injection pressure is located: in a separate pump body, or inside the injector housing on the head. • Confirm whether there is a common high‑pressure rail or manifold feeding several injectors, or only individual high‑pressure lines going to each injector. • Make sure there is no air line going to the injector if you decide it is not an air-assisted type.
