Q

Which of the following problems may occur when using fuel oil with a high sulphur content?

🔍 Key Concepts

• Fuel oil sulphur content and how it behaves during combustion • Formation of sulfurous/sulfuric acids in the engine and exhaust system • Effects of acid formation on engine metals and components over time

💭 Think About

• When high-sulphur fuel burns, what chemical compounds can form in the exhaust and on cool metal surfaces? • Which of the listed problems is most directly linked to acidic by‑products attacking metal parts rather than affecting timing or lubrication? • Think about long‑term effects on engine parts like exhaust valves, turbocharger, and exhaust gas passages—what type of damage would acids cause?

✅ Before You Answer

• Identify which choice is clearly a chemical/material damage issue rather than a timing or combustion event issue • Ask: Which option would most likely show up as damage to metal surfaces in exhaust or cylinder areas? • Eliminate any options that deal mainly with ignition timing or fuel mixing with lubricating oil, not with acid attack.
