(2) Ring gear

2.13.3 Function of flywheel

The flywheel stores inertial
combustion stroke and transfers this power generated
in the engine externally.
In addition, a ring gear is provided that receives power
from the starter while starting the engine and causes
the crankshaft to rotate.
Based on its inertia, the flywheel causes the engine to
rotate smoothly during
combustion stroke.
