🔍 Key Concepts

• thermal stresses in the cylinder head material • the role of cooling water passages in temperature control • how local overheating around valves or in the head can cause cracking

💭 Think About

• Think about which option would most likely cause part of the cylinder head to run much hotter than surrounding areas, creating high thermal stress. • Consider how problems with heat removal versus problems with air or gas flow affect metal temperature in the head. • Ask yourself: which condition would persist over time and gradually weaken the metal rather than just slightly change performance?

✅ Before You Answer

• Verify which option directly affects cooling water flow or heat removal from the cylinder head. • Check whether each option would increase localized metal temperature in the head area. • Eliminate options that mainly affect engine performance (power/combustion quality) but not the head’s ability to get rid of heat.
