🔍 Key Concepts

• Engine monitoring systems on modern vessels • Typical causes of engine damage (overheating, loss of lubrication, overspeed) • Difference between a single-parameter alarm and a comprehensive protection system

💭 Think About

• Think about what physical conditions, if they go out of normal range, can quickly destroy an engine and therefore need automatic protection. • Ask yourself: do marine engines usually have just one type of sensor for protection, or several different kinds working together? • Consider real engine panels you’ve seen: what kinds of warning lights or gauges are there that could trigger an alarm or shutdown?

✅ Before You Answer

• Identify which listed options are commonly monitored on engine control panels (look at normal gauges and warning lights). • Consider which conditions can cause catastrophic engine damage in seconds or minutes if not corrected. • Verify whether marine engine protection systems are typically designed around one parameter or multiple parameters.
