What is the primary function of a governor in an engine?

The primary function of a governor in an engine is to regulate engine speed and maintain a constant performance. A governor achieves this by adjusting the fuel supply or other engine parameters based on the load conditions. This means that when the engine load increases (for example, when the vehicle is going uphill), the governor senses the change and increases fuel delivery to compensate and keep the engine running at a set speed. Similarly, if the load decreases, the governor will reduce the fuel supply to prevent the engine from exceeding a specified RPM.

This function is essential for applications where consistent engine performance is critical, such as in heavy-duty equipment and engines used in various industrial applications. By maintaining a stable speed, the governor helps ensure efficient operation and prevents engine damage that could arise from excessive RPM.
