🔍 Key Concepts

• Engine governor functions on a diesel or marine engine • Difference between speed control (keeping RPM steady) and response time (how fast the governor reacts) • How a governor behaves when the load suddenly increases or decreases

💭 Think About

• Which term best describes how WELL the governor holds engine speed steady when the load changes, not how FAST it reacts? • Think about which option refers to maintaining a nearly constant RPM under varying loads, rather than limiting maximum load or describing a setting/characteristic. • Which of these terms would you expect to be used when evaluating if an engine runs smoothly at a constant speed despite waves, current, or electrical load shifts?

✅ Before You Answer

• Be clear on the difference between governor accuracy/constancy and governor response time. • Check which term is commonly used in marine engineering texts to describe resistance to speed variation under load changes. • Eliminate any choice that mainly refers to a maximum permissible load or a deliberate speed error setting rather than smoothness of speed.
