centrifugal governor

A centrifugal governor is a specific type of governor with a feedback system that controls the speed of an engine by regulating the amount of fuel (or working fluid) admitted, so as to maintain a near-constant speed, irrespective of the load or fuel-supply conditions. It uses the principle of proportional control.

It was invented in 1788 by James Watt to control his steam engine where it regulates the admission of steam into the cylinder(s). Its widest use was on steam engines during the Steam Age in the 19th century. It is also found on internal combustion engines and variously fueled turbines, and in some modern striking clocks.

How does a governor works?

The governor system is like a cruise control system. It maintains the speed of your lawn mower or outdoor power products. When Briggs & Stratton governors are adjusted properly, they keep your speed steady regardless of engine load – the amount of work the engine must perform.

What is Governor in mechanical engineering?

A governor, or speed limiter, is a device used to measure and regulate the speed of a machine, such as an engine.

What does the governor do in a car?

A car speed governor, or speed limiter, is a device that sets and limits a car’s top speed. When a car that is fitted with a speed governor reaches a preset top speed, the device begins to curtail combustion and limits the supply of fuel and air to the engine.
