Q

Motor vessels usually have independent lube oil systems for main engine and main reduction gears because __________.

🔍 Key Concepts

• lube oil system functions in both diesel engines and reduction gears • difference between contamination and temperature control in lubrication systems • how additives and wear particles in engine oil compare to what gears require

💭 Think About

• Think about what happens to the lubricating oil as it circulates through a diesel main engine. What kinds of by‑products and particles might end up in that oil? • Compare the operating conditions of a main engine (combustion, high temperatures, soot, fuel dilution) with those inside a reduction gear box. Which system is more sensitive to dirty or chemically altered oil? • Ask yourself: is the main concern about cooling equipment, oil additives, or protecting precision gear surfaces from something coming from the engine?

✅ Before You Answer

• Identify which option focuses on protecting the reduction gears from something that originates in the engine • Eliminate any choices that talk about equipment (coolers, centrifuges) rather than the reason separate systems are used • Verify which choice deals with engine-generated contaminants or by‑products and their effect on gear operation
