1 - Flywheel2 - Toothed wheel3 - Phonic wheel for rpmThe flywheel makes the engine turn smoothly,
by accumulating energy during the active stages (expansions) and
returning it during passive stages. The flywheel is designed to allow the engine
to idle without stalling and overcome the friction developed by
the engine during no-load operation.
