🔍 Key Concepts

• heat flow from piston crown to cooling spaces in large low-speed two-stroke diesels • typical failure modes from overheated piston crowns vs piston skirts vs crossheads • properties of heavy fuel oil combustion (high temperature, deposits, corrosion)

💭 Think About

• Which piston area is directly exposed to the hottest combustion gases, especially with heavy fuel oil? • If cooling is insufficient, which component will see the earliest and most severe temperature rise? • Which of the listed effects is directly caused by localized overheating at the combustion surface rather than by fuel chemistry changes?

✅ Before You Answer

• Identify which component (crown, skirt, crosshead, fuel) is most dependent on effective internal cooling to survive gas loads • Ask whether cetane number is something the engine can change, or a property of the fuel as delivered • Consider which failure mode is commonly associated with burning, melting, or corrosion of surfaces in direct contact with combustion gases when burning heavy fuels
