The
flywheel is installed on the rear end of the
crankshaft. Its inertia keeps the flywheel turning at a
constant speed, while
the
crankshaft tends to speed up
during the power stroke and to slow
down
during other
strokes.
The
flywheel has a ring gear, which mesh with the
drive pinion of the starter.
The
flywheel has
also
marks
TC and fuel injection
timing lines on its
outer
rim.
The
lines
of
fuel injection
timing shows the fuel injection timing and the
mark
TC
shows
the
piston's
top
dead center,
when
they
are
aligned with the alignment
mark
on the rear end plate.
On
the
circumference of the flywheel are stamped the
top dead center (1TC)
mark
for
the 1st cylinder and four
lines indicating every
0.087
rad. (5°) of
crank
angle from
0.175 rad. (10°)
to
0.436 rad. (25°) before
mark

the
air flow, is
absorbed
by
the element (1) and thus prevented from
