🔍 Key Concepts

• Function of a diesel engine governor and what it regulates • What settings must be re-established after the internal hydraulic/oil system of a governor is opened or drained • Difference between permanent control characteristics (like idle, max load) and stability/response characteristics (like droop, compensation)

💭 Think About

• Think about which adjustment directly depends on the internal oil-filled control system inside the governor, and would be disturbed whenever the oil is drained and refilled • Ask yourself: after renewing governor oil, what is the FIRST critical setting you must verify so that the engine can be safely started and run without overspeeding or stalling? • Consider which of the listed items is a basic operating reference point for the governor, and which are more about fine‑tuning performance under varying load

✅ Before You Answer

• Make sure you know what speed droop actually changes in a generator/propulsion governor and whether it must always be reset after maintenance • Clarify what the compensation adjustment does in terms of stability vs. basic speed setting • Identify which one of the four options is the fundamental baseline speed control that the engine must have correctly set before adjusting anything else
