The throttle is pulled toward the closed position.Īs the load on the crankshaft increases, the flyweights spin more slowly. As they open, they apply pressure to the governor cup and governor crank, which are linked to the throttle.

ELECTRONIC GOVERNOR Mechanical Governor:Ī mechanical governor uses gears and flyweights inside the crankcase as a speed-sensing device that detects changes in the load and adjusts the throttle accordingly.Īs the crankshaft spins, centrifugal force causes the flyweights to open.

Types of Governor:įollowing types of governor are mostly used :

If parameters of the loop change, it will affect the entire loop and fuel will automatically be corrected to maintain the desired set point.

Closed Loop Definition: When used as an automatic control system for operation or process in which feedback in a closed path or group of paths to maintain output at a desired level.

The governor functions the same as the car driver.A way to stabilize the engine after a fuel change has been made.

A way for the governor to change the fuel to the engine or turbine(Moving the rack or fuel valve)(The driver moves the throttle).A way to compare the actual speed to the desire speed (The driver compares two item mentally ).A way to sense the actual speed (The driver refers to speedometer).A way set to desire the speed (The driver set the desired speed mentally.).Governor is a device which senses the speed of an engine or turbine and controls the fuel (or steam) to the engine or turbine to maintain the speed at a desired level to meet changes in load or horse power o/p required.įor further understanding take an example:
