M502.73 3
Objectives
On completion of this period , you should be able to
Know
• What is Fly Wheel?
• Function of Fly Wheel
• Applications of Fly wheel
• Comparison between fly wheel and governor
M502.73 4
• A device which acts as a reservoir of energy.
• Absorbs energy when an excess energy is delivered
from engine / prime mover
• Releases the energy to meet the requirements of the
engine / machine load.

COMPARISON
FLYWHEEL• Reduce the Cyclic
variation of speed due to difference in input and out put.
• Action is continuous from cycle to cycle.
• Regulates the supply of energy during a cycle.
• No control over the quality of working fluid.
GOVERNOR• Maintain a constant speed
of Prime mover when the variation of speed is due to fluction of load.
• Action is Intermittent when load changes on engine.
• Regulates Input energy according to the Load from cycle to cycle.
• Changes the Quantity of the working fluid.
