🔍 Key Concepts

• Function of injection pump plungers in controlling fuel quantity and timing • How surface wear, erosion, or pitting changes clearances and sealing surfaces • Relationship between fuel metering, timing, and engine performance

💭 Think About

• Think about what the plunger is supposed to do each stroke. How would rough or worn surfaces change how much fuel is actually delivered? • Would damage to the plunger affect only one operating condition (like low speed), or could it influence the whole operating range? • Is it realistic that metal surface damage would be corrected by the normal flow of fuel over time, or would it tend to get worse?

✅ Before You Answer

• Identify the primary role of the plunger: is it more about sealing, timing, or mechanical strength? • Consider whether irregular surfaces increase leakage or change the effective stroke that delivers fuel. • Ask if any option suggests a condition that is self‑healing; verify if that is mechanically reasonable for hardened pump parts.
