For most auxiliary diesel generator engines, the over speed trip device will stop the engine by __________.

🔍 Key Concepts

• Overspeed trip device function on diesel generator engines • Relationship between governor and fuel rack / fuel supply • Why stopping an engine by cutting lubricating oil is not used as a protection method

💭 Think About

• When an engine overspeeds, what is the fastest and safest way to remove the source of power driving the crankshaft? • Is the overspeed trip usually an adjustment of normal speed control, or a separate safety mechanism that acts independently of the operator? • Think about which component the overspeed trip must act on directly to be reliable even if the governor has already failed.

✅ Before You Answer

• Eliminate any choice that relies on damaging the engine (e.g., removing lubrication) as a standard safety measure. • Decide whether an overspeed trip should act on normal speed-setting controls or on a dedicated shutdown linkage. • Confirm that the method involves directly stopping fuel and/or air so the engine cannot keep accelerating.
