Q

Sudden unloading of a diesel engine can cause which to occur?

🔍 Key Concepts

• Diesel engine governor action when load suddenly drops • Relationship between engine speed, fuel delivery, and exhaust temperature • Typical visible and automatic responses to overspeed conditions

💭 Think About

• When you suddenly remove load from a running diesel, what happens to engine speed before the governor can fully react? • How would that rapid change in speed affect exhaust temperature, smoke color, and any protective devices? • Which of the listed effects is most immediate and critical to protect the engine when speed rises too high?

✅ Before You Answer

• Decide which option is a protective safety response rather than a gradual performance change • Consider whether smoke color and exhaust temperature usually rise or fall when load is suddenly removed • Think about the governor: what happens first in the seconds right after the load is taken off?
