🔍 Key Concepts

• Diesel engine protective devices such as shutdowns vs alarms • Typical lube oil system safety functions on diesel auxiliaries • What engine condition can cause immediate damage if not corrected

💭 Think About

• Which of these conditions, if allowed to continue for even a short time, is most likely to cause rapid engine damage or failure? • For each option, decide whether it is more commonly associated with an alarm only, or with an automatic shutdown for protection. • Think about which parameter is most critical to maintaining an oil film between moving parts in the engine.

✅ Before You Answer

• Identify which lube oil parameter indicates a loss of lubrication rather than just a sub‑optimal condition. • Consider whether high exhaust temperature is usually handled by load reduction/alarms or full automatic shutdown. • Ask: which of these is most likely to be wired to a pressure‑activated trip on the engine safety system?
