The purpose of an engine governor is to provide ______ regardless of the load.

• A. increased torque
• B. variable rpm
• C. constant engine speed
• D. fuel economy

Answer: (C)

A governor’s job is to keep the engine speed steady. It continuously senses how fast the engine is running and adjusts the fuel delivered to match the set speed, so changes in load don’t cause the RPM to swing. When load increases and would slow the engine, the governor opens the throttle to raise fuel flow and restore the speed. When the load drops, it reduces fuel to avoid overspeed. So the primary purpose is maintaining a constant engine speed, not increasing torque, not allowing RPM to vary, and not primarily aiming for fuel economy.
