🔍 Key Concepts

• Hydraulic governor operation and what the compensating needle valve actually controls • The importance of steady, representative operating conditions when making fine adjustments • How engine load and temperature affect governor response and stability

💭 Think About

• In what condition will the engine and governor behavior best represent how the system normally runs over time? • How would changing load during adjustment affect your ability to judge whether the governor is stable or hunting? • Why is engine temperature important when setting any control related to fuel delivery or speed control?

✅ Before You Answer

• Verify under which condition the engine speed and temperature are most stable and repeatable • Check which choice gives a situation that is easy to hold steady for observing small speed changes or hunting • Confirm that the selected condition matches how the manufacturer expects the governor to be tuned for normal service
