The idea behind this question is how a governor keeps engine speed constant. A speed regulating governor is designed to hold the engine at a predetermined speed by using a feedback loop that meters fuel to counteract changes in load. When the engine tends to speed up, the governor reduces fuel; when it tends to slow down, it increases fuel, so the actual speed stays at the set value. This is typically achieved with a speed-sensing mechanism (like a flyweight system) connected to the fuel-control lever, creating a continuous corrective action to maintain the desired rpm. Other governors adjust fuel based on different principles—load sensing focuses on responding to changing load, and a proportional governor modulates output in proportion to speed error—but the defining purpose of a speed regulating governor is to keep the engine at a fixed, predetermined speed.
