Which device will normally shut down a diesel engine after it exceeds its maximum speed setting?

🔍 Key Concepts

• Governor vs. trip device – what each one does in a diesel engine • Difference between controlling speed continuously and emergency shutdown • How an engine is protected when the governor fails or is overridden

💭 Think About

• Ask yourself: which device works all the time to regulate speed, and which device acts ONLY when speed goes dangerously beyond the safe maximum? • Think about what happens if the main speed control fails or the engine suddenly runs away—what special protective device is there just for that? • Look at the words in each choice: which sound like a control/adjustment function, and which sound like a final protective action?

✅ Before You Answer

• Identify which device is meant for normal speed regulation during operation versus safety protection in an emergency. • Check which option describes a device that will actually shut the engine down, not just reduce or limit fuel. • Confirm that the device you pick is designed to act only at a set overspeed point, independent of the operator.
