Function of governor in IC engine

Governor is the mechanical device that helps to control the speed of the engine by regulating fuel supply.

It helps to maintain the mean speed of the engine by controlling the supply of fuel to the engine.

When the load on the engine increases, the governor increases the supply of the fuel and when the load on the engine decreases, the governor decreases the supply of fuel.

Therefore, the main purpose of the governor is to maintain the mean speed of the engine by regulating fuel supply.

The governor is mainly classified into two types which are the centrifugal governor and inertia governor

The centrifugal governor is consists of centrifugal masses attached to the revolving arms. As the governor starts to rotate, these centrifugal masses move away from its axis of rotation.

The movement of these balls is used to control the movement of the sleeve at the base of the spindle. The mechanism connected to these sleeves controls the supply of fuel.

Function of governor in IC engine:

The main function of the governor is to maintain the mean speed of the engine. For that purpose, the governor controls the opening of fuel supply as per the load on the engine.

When the load on the engine increases:- When the load on the engine increases, the speed of the engine decreases. as the speed decreases, the governor helps to increase the opening of the fuel supply valve.

Therefore with an increase in fuel supply, the speed of the engine also increases to the mean speed.

When the load on the engine decreases:- As the load on the engine decreases, the speed of the engine suddenly increases. In this condition, the governor helps to decrease the opening of the fuel supply valve.

Therefore with decreases in fuel supply, the speed of the engine also decreases to the mean speed.
