🔍 Key Concepts

• Unit injector vs. pump-and-line systems on diesel engines • How high-pressure fuel is delivered to each cylinder (external lines vs. internal to injector) • Visual clues in the figures showing multiple delivery valves and line fittings versus a single, head-mounted injector body

💭 Think About

• Look at which figures obviously need separate high-pressure lines to each cylinder and which figure could be mounted directly in the cylinder head without external lines. • Ask yourself: in a system with no high-pressure lines, where must the pumping and injection functions be combined? In a separate pump housing away from the cylinder, or inside the injector itself? • Compare the shapes: which figure most closely resembles something that would sit in the cylinder head under a rocker arm, rather than on the engine side feeding several cylinders?

✅ Before You Answer

• Identify which figures clearly show multiple outlets or ports where high‑pressure lines would attach – those are less likely the right choice. • Focus on the figure that looks like a single-cylinder injector with its own spring and plunger, not a multi‑cylinder pump body. • Before choosing, ask: "If I removed all high‑pressure lines from this setup, would fuel still be able to reach the cylinder at injection pressure?" Pick the figure that makes this realistically possible.
