What is the function of a governor on an engine?

Limits the amount of fuel
Controls engine temperature
Limits RPMs
Regulates air intake

The correct answer is: Limits RPMs

The function of a governor on an engine is to limit RPMs, which is critical for maintaining safe and efficient engine operation. The governor monitors the engine's speed and adjusts the fuel supply to prevent the engine from exceeding a predetermined RPM threshold. This ensures that the engine does not operate beyond its designed capacity, which could lead to mechanical failures or safety hazards. By regulating the speed, the governor helps maintain optimal performance and prolongs the lifespan of the engine. Understanding this role is essential for anyone working with engines, particularly in the context of operating machinery that relies on controlled engine performance.
