Question 1 of 270705eccefa1bacbc34ba4d47712

After each speed change, the compression of the diesel engine governor speeder spring is returned to a constant value, regardless of the amount of movement of the fuel control mechanism and engine load. Hence, this results in __________.

Question 1 of 27070

🔍 Key Concepts

• Governor speed control characteristics (how speed changes with load) • Difference between isochronous and speed droop governing • Role of the speeder spring compression in setting engine speed

💭 Think About

• Ask yourself: if the speeder spring compression always returns to the same value after a speed change, what does that say about how the governor treats speed versus load? • Consider which type of governing keeps the set (reference) speed effectively constant once adjusted, and which type allows a deliberate change in speed as load changes. • Think about whether a constant speeder spring compression would allow or prevent a permanent speed drop when load increases.

✅ Before You Answer

• Verify which governing mode has no permanent speed change between no-load and full-load at a given setting. • Check the definition of speed droop: does it involve a constant or changing speeder spring compression as load changes? • Confirm how isochronous governing is usually described in textbooks with respect to reference speed and governor spring setting.
