IGNITION COILS

(Bae 920A)
(Beru 0.040.100.029)
The coils are fastened by means of a bracket
to the camshaft covers and are closed mag-
netic loop type. They are formed from a lay-
ered pack, whose central core (broken by a
narrow gap) carries both windings.
The windings are placed in a moulded plastic
container embedded in epoxy resin, which
gives them exceptional dielectric properties.
Because the primary winding is so close to
the magnetic core, little magnetic flux is lost
and coupling with the secondary winding is
maximised.
