Toyota Ignition Coil Pack
Ignition coil according to the magnetic circuit is divided into
open magnetic type and closed magnetic type two. The traditional
ignition coil is an open magnetic type, and its iron core is
stacked with 0.3mm silicon steel sheets, and there are secondary
and primary coils around the iron core. The closed magnetic type
uses an iron core similar to Ⅲ around the primary coil, and then
winds the secondary coil outside, and the magnetic field line is
formed by the iron core. The advantages of the closed magnetic
ignition coil are less magnetic leakage, small energy loss and
small size, so the electronic ignition system generally uses the
closed magnetic ignition coil.
