The
purpose of the flywheel in an IC engine is :
To
regulate the fuel supply
To
keep the output power constant at the crank shaft
To
increase the power capacity of the engine
To
reduce the vibration in an engine
To
keep the output power constant at the crank shaft
(i)
A flywheel is used to control the variations in speed during each cycle of an
engine.
(ii)
A flywheel attached to crank-shaft makes moment of inertia of rotating parts
quite large.
(iii)
When supply of energy is more that it stores energy and when it is less, it
releases energy.
Hence,
the correct option is (B).
