On a diesel engine equipped with an isochronous governor, if the 'speed droop' control is reduced to the 'zero' setting, the engine __________.

🔍 Key Concepts

• Isochronous governor characteristics in diesel engines • Meaning of speed droop and what a zero droop setting implies • Relationship between engine speed, load changes, and fuel supply in governor-controlled systems

💭 Think About

• Think about what an isochronous governor is designed to do with respect to engine speed when the load increases or decreases. • Ask yourself: if the speed droop is set to zero, how much change in speed is the governor trying to allow as load changes? • Consider which of the answer choices describes behavior that matches a governor whose main purpose is to keep speed nearly unchanged under varying load.

✅ Before You Answer

• Be clear on the difference between droop control (speed decreases as load increases) and isochronous control (speed remains the same with load changes). • Check which options describe unstable or unsafe behavior that a properly adjusted governor is specifically designed to avoid. • Verify which choice best matches a system where fuel flow is automatically adjusted to maintain nearly constant speed as load varies.

speed will drop drastically with any increase in load

will stop due to zero fuel supply

will stall upon application of load
