🔍 Key Concepts

• Study how the bridge contacts the two valve stems and the single rocker arm above it. • Look closely at the arrows on the valve head in Figure 2 and how they relate to movement or rotation. • Notice the indicated oil flow path and what internal parts it passes through inside the bridge.

💭 Think About

• Ask yourself: What motion from the rocker arm is transmitted through this bridge, and how many valves receive that motion? • Does the internal spring-and-plunger assembly look more suited to opening/closing, to lubrication, or to causing turning/rotation of the valve? • Why would a designer want the exhaust valves to move or behave differently from simple up‑and‑down motion, and which choice best matches that purpose?

✅ Before You Answer

• Verify which choice specifically mentions more than one valve being operated by a single component. • Check which answer choice best matches the circular arrows on the valve head shown in Figure 2. • Confirm whether the illustrated oil flow and internal parts are there mainly for lubrication, closing force, or to support some other function.
