1 Battery
2 Ignition starting switch
3 Ignition coil
4 Switchgear
5 Transmitter
6 Ignition distributor
7 Spark plug(s)
FUNCTIONING OF THE IGNITION SYSTEM
The ignition system consists of the following components:
Battery (1) as the energy source. The primary current flows from the battery through the ignition starting
switch (2) (when switched on) and the primary winding of the ignition coil (3) back through the switchgear
(4). The activation of the interruption of the primary current by the switchgear is controlled by an induction
pulse generator (5) in the ignition distributor (6).
At the moment when the primary current is interrupted, a high voltage is induced in the secondary winding
of the ignition coil, which is distributed by the ignition distributor to the appropriate spark plug (7).
