What does the flywheel do in a lawn mower engine?

The flywheel on a Briggs & Stratton small engine was originally developed to maintain constant angular velocity of the crankshaft. Simply, it stores the momentum from combustion to keep the crankshaft turning in between the engine's power strokes.

Correspondingly, what is the main function of a flywheel?

A flywheel is a mechanical device specifically designed to efficiently store rotational energy. Flywheels resist changes in rotational speed by their moment of inertia. For example, flywheels are used in reciprocating engines because the active torque from the individual pistons is intermittent.

Why do we need flywheel?

A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed.
