If the a main propulsion diesel engine governor works irregularly with a jerking motion, a possible cause can be __________.

🔍 Key Concepts

• how a diesel engine governor responds to changes in speed and load • which components would cause intermittent, jerky motion versus a one-time trip or steady malfunction • difference between linkage/control problems and protective devices like overspeed trips or overload cams

💭 Think About

• Ask yourself: which option would most directly affect the smoothness of the governor’s mechanical motion as it moves to control fuel? • Consider: which items are designed to act suddenly only at specific conditions (like overspeed), rather than causing continuous jerky behavior? • Think about whether each choice would tend to cause a gradual/steady error, a single shutdown event, or repeated irregular motion.

✅ Before You Answer

• For each choice, decide whether it operates continuously with the governor or only at specific limit conditions (overspeed, overload). • Identify which component actually moves with or influences the fuel control rod/linkage during normal operation. • Eliminate any option that would more likely cause a trip or shutdown rather than ongoing jerking movement.
