🔍 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.
