Question 1 of 27070

A change in engine speed is required before a governor is able to make a corrective movement of fuel rack. This aspect of governing is commonly expressed as a percent and is known as __________.

🔍 Key Concepts

• speed droop in engine governors and how it relates to % change in speed • difference between sensitivity (smallest detectable change) and droop (required change to act) • meaning of isochronous governing (constant speed regardless of load)

💭 Think About

• Ask yourself: which term is specifically defined as the percent change in speed between no‑load and full‑load at which the governor changes fuel to maintain control? • Consider: does sensitivity describe a required speed change before motion, or the minimum speed change the governor can notice? • Think about isochronous governing: would an isochronous system allow any intentional speed change with changing load?

✅ Before You Answer

• Identify which term is usually expressed as a percentage of rated speed between two load conditions • Confirm which choice refers to steady‑state speed regulation under varying load, not response time • Eliminate any option that describes response speed (how fast it reacts) rather than how much speed must change before it reacts
