🔍 Key Concepts

• Relationship between air filtration and abrasive particles in engine cylinders • Role of lubricating oil film in reducing metal-to-metal contact and wear • How fuel type/quality can affect combustion deposits and corrosion inside the cylinder

💭 Think About

• Ask yourself which of these factors can introduce or prevent abrasive or corrosive material from reaching the cylinder liner surface • Consider whether poor performance in any one of these areas could reasonably increase wear, even if the others are good • Think about how engineers try to extend cylinder life in large marine diesels—what systems do they focus on improving or monitoring?

✅ Before You Answer

• Verify which options directly influence abrasive wear (dust, particles) on the liner • Verify which options directly influence lubrication quality and oil film thickness on the liner • Verify which options directly influence corrosive or deposit-related wear due to combustion products and fuel impurities
