The flywheel stores energy during the power stroke and supplies it to the crankshaft during the idling stroke i.e suction, compression and exhaust. This is also called as “store of energy” in the vehicle.

The size of flywheel depends upon the number of cylinders and general construction of the engine. The size of flywheel is small for two-stroke engine as there is alternate power stroke, but size of flywheel is more in case of 4-stroke engine due to only one power stroke out of four strokes.
