🔍 Key Concepts

• Governor hunting: what it means and what typically causes it in a hydraulic governor system • Difference between steady‑state speed setting changes (like droop or speeder spring) versus stability/damping adjustments • Role of the compensating (damping) system in preventing oscillations in engine speed

💭 Think About

• First, think about what governor 'hunting' looks like in terms of engine RPM. Is it a stability problem, or simply the wrong speed setting? • Which component in a hydraulic governor is specifically intended to slow down or smooth out rapid corrections so the governor doesn’t overshoot? • Look at each choice and ask: does this change the desired speed/speed-load relationship, or does it change how aggressively the governor responds?

✅ Before You Answer

• Be clear on the definition of hunting: repeated over‑correction and oscillation of speed, not just being at the wrong speed. • Identify which adjustment is normally used to change stability/damping rather than changing speed or load‑sharing characteristics. • Verify in your study materials how a compensating (damping) needle/relief affects the rate of oil flow and governor response.
