🔍 Key Concepts

• Understand what governor droop means in diesel engine speed control • Difference between isochronous (zero droop) and droop governing modes • Relationship between engine load and RPM in each mode

💭 Think About

• Ask yourself: In a zero droop / isochronous system, what is the governor trying to keep absolutely constant, even as load changes? • Consider: With increasing load on the generator, what would normally happen to RPM if the governor did nothing, and what must the governor do in zero droop mode to prevent that? • Look at each choice and ask: Does this describe the RPM changing with load, needing manual control, or staying constant automatically?

✅ Before You Answer

• Verify whether zero droop means some RPM change with load or no RPM change with load • Check if a properly functioning governor in zero droop mode would ever require manual RPM adjustment just because load changed • Eliminate any options that suggest the governor has no control or that RPM will fall off significantly under load in zero droop mode

How is the diesel engine operating RPM affected when a 'ZERO DROOP' setting is selected on the governor?

The RPM will drop to low idle when load is applied.

The RPM must be manually controlled by the load limit knob.

The governor has no control over RPM in this mode.

The RPM will remain the same with or without load.
