🔍 Key Concepts

• Follow the scavenger air (intake air) flow path shown in green and see where it enters the cylinder head. • Distinguish between inlet (intake) valves and exhaust valves by looking at which manifold (air vs exhaust) they connect to. • Note what parts like springs, valve stems, and ports are being labeled by the different letters/numbers near the top of the right‑hand cylinder.

💭 Think About

• On the right cylinder head, which label is pointing directly to the valve that opens to the incoming air passage, not the exhaust passage? • Which of the marked items is actually the valve itself (valve head/seat or stem), and which are just related components such as springs, rocker arms, or ports? • How does the color code (green for scavenger air, orange for exhaust) help you see which side must be the inlet side and which labels lie on that side?

✅ Before You Answer

• Verify which labels are connected to the green scavenger air passage rather than the orange exhaust passage. • Confirm that the label you pick is marking the valve component itself, not the rocker arm, spring, or guide. • Make sure the label you choose is on the right‑hand cylinder head, since the answer choices reference that side’s numbering.
