🔍 Key Concepts

• Heavy fuel oil properties and how its viscosity and temperature affect combustion and injector operation • Purpose of cooling injector components that are in contact with very hot fuel and combustion gases • Effects of overheating at the injector nozzle tips (e.g., deposits, erosion, preignition)

💭 Think About

• Think about what actually happens to injector parts when very hot, viscous heavy fuel oil is used over long periods. Which problem would cooling directly reduce? • Which option describes a problem that typically occurs at the nozzle outlet exposed to combustion heat and hot fuel, rather than deep inside the system? • Consider which of the listed problems is most closely associated with overheating and deposit formation on fine passages and holes.

✅ Before You Answer

• Match each choice to a known injector problem: corrosion, delivery rate, preignition, or nozzle deposits, and ask which one is strongly heat‑related at the nozzle tips. • Ask yourself: is the main goal of internal cooling to improve performance/economy, or to protect precision parts from heat‑related damage and fouling? • Mentally picture the very small holes in an injector nozzle and what excessive heat plus heavy fuel would tend to do there over time.
