Question 243Motor Plants - 1st Asst/Chief

The correct answer is D) prevent governor hunting. The compensating adjustment in a diesel engine hydraulic governor is used to prevent the governor from hunting or oscillating around the desired engine speed. This is achieved by introducing a damping effect that reduces the sensitivity of the governor to minor speed fluctuations, ensuring a more stable engine speed control. The other answer choices are incorrect because: A) Compensating adjustment is not used to compensate for low oil level, which is typically monitored by a separate system. B) Increasing governor promptness is not the primary purpose of the compensating adjustment. C) Limiting engine load is not the function of the compensating adjustment; that is typically handled by other governor mechanisms.
