6.18) Ignition
unit:
)*
The
engine is
equipped with
a dual ignition
unit of
a breakerless,
capacitor
discharge
design,
with
an intergrated 250
W
generator.
The
unit consists
of the
generator
stator in
the ignition
cover, the magneto ring
on
the crankshaft, 4
external
trigger coils for ignition,
1
external
trigger
coil
for rev-counter
and
the
ignition
coils
and electronic box in
an
interference
suppression
box
attached on
the aircraft.
Two independent
charging
coils located
on
the
gendrator
stator
supply
one ignition
circuit
each. The energy is
stored
in
capacitors. At
the moment
of ignition
the
two each
external
trigger
coils actuate
the discharge
of the capacitor
to the
primary
circuit
of the
dual ignition
coils. The
operation
of the ignition
unit
is
completely free
of maintenance.
