Description
(1) ignition coil
"a" 3-way black connector
Make: DELPHI
Role
The ignition coil is for converting low voltage into high voltage
After convertion, the high voltage supplies the sparking plugs
Function
(1) Control of ignition coil
(2) earth
3 Power supply 12 V
(4) high voltage diode
(5) electromagnetic compatibility filtering device
(6) spark plug
(7) engine earth
The soft iron core channels and concentrates the magnetic flow
The greater and faster the variation in the magnetic flux in the coil, the higher the voltage created
The number of spirals of the primary coil differs from that of the secondary coil
The resulting induced voltage is equal to the ratio of the number of spirals of the primary coil to that of the secondary coil
