Grashof’s Law states that for a four-bar linkage system, if the sum of length of shortest and longest of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links , then the shortest link can rotate freely with respect to neighbouring link. In a four bar chain there are…
Belt drive is a mechanism in which power is transmitted by the movement of a continuous flexible belt. It is used to tranmit roational motion from mechanical element to another.A belt is looped strip of flexible material which is used to mechanically link two or more rotating shafts. A belt drive is found in almost…
It is also called Spring Loaded Governor. It is a special type of governor which has a spring attached between the balls of the governor. This spring is called Main Spring. The main spring is stretched and placed between the balls, this means that the main spring always exert a inward force to both the…
The balls in Inertia Governor are arranged in such a way that the inertia forces caused by angular acceleration or retardation of the governor shaft tend to change their position. Inertia Governor is more sensitive than centrifugal governor but in this governor, it is very difficult to completely balance the revolving part. So Inertia Governors…
Heat Balance Sheet is an account of heat supplied and heat utilized in various ways in the IC engine. Heat balance sheet is used to get necessary information regarding the performance of IC Engine. Heat balance sheet can be done on second basis or minute basis or hour basis. Since heat balance sheet is account of heat supplied and…
Porter Governor is a modification of Watt Governor with central load attached to the sleeve. This load moves up and down the central spindle. The additional force increases the speed of revolution required to enable the balls to rise to any predetermined level. Construction :- Porter governors has two fly balls which are attached to…
Proell Governor is a different type of governor in which the fly balls are connected to the spindle using an extended arm. The fly balls are mounted on this additional arm. Like the porter governor, proell governor also has central weight which increases the speed of rotation. Proell Governor functions much more accurately than other…

Hartnell Governor is spring loaded centrifugal governor. It contains an additional spring which is used to apply an additional force to the sleeve. This governor has a nut place at the top of the spring . This nut is used to adjust the force of the spring. Construction:- Hartnell Governor has a spindle which is…
Fins are the extended surfaces designed to increase the transfer rate for a fixed surface temperature or lower surface temperature for a fixed heat transfer rate.These are generally used to increase the heat transfer rate to the environment. It can most commonly be seen in the internal combustion engine to transfer heat to the environment…
