🔍 Key Concepts

• Function and purpose of valve rotators in diesel engines • Which cylinder head valves experience the highest heat and gas flow during engine operation • Difference between service/operating valves and special-purpose valves like starting, relief, and blowdown

💭 Think About

• Think about which valve operates every power stroke and is most exposed to hot combustion gases • Consider which type of valve is most prone to burning, pitting, or carbon buildup and would benefit from even wear on the valve face and seat • Ask yourself: which valve’s reliability and sealing is most improved by slowly rotating it during normal engine operation?

✅ Before You Answer

• Identify which listed valves are in continuous cyclic operation during engine running versus only occasional or emergency use • Recall that valve rotators help prevent concentration of wear and carbon on one spot of the valve seat • Verify which valve, if it fails to seal properly due to burning or distortion, will most directly affect engine performance and exhaust gas flow
