The three conditions which cause engine shutdown are overspeed, low lube oil pressure, and which other condition?

🔍 Key Concepts

• Engine protective devices that automatically shut down to prevent catastrophic damage • Difference between temperature-related problems and pressure-related problems in cooling and lube oil systems • What happens to metal parts and clearances if an engine runs too hot or without enough lubrication

💭 Think About

• Which condition, if ignored for even a short time, is most likely to quickly destroy the engine? • Among temperature and pressure problems listed, which one is commonly wired into automatic shutdown rather than just an alarm? • Think about what the cooling system is protecting and what failure mode is most dangerous: too hot, too cold, too much pressure, or too little flow?

✅ Before You Answer

• Identify which options are temperature issues and which are pressure issues • Decide which condition is typically treated as an alarm only versus a full automatic shutdown on most marine diesels • Consider which condition directly threatens immediate engine seizure or major damage if it continues even briefly
