The secondary winding of the ignition coil is connected to high voltage wires and spark plugs. The induced voltage in the ignition coil causes a spark to flash, first between the distributor pin and the high voltage wire of the corresponding cylinder, then between the spark plug electrodes in the cylinder.
During the opening of the breaker contacts, small sparks arise between them, which eventually burn the contact plane. Very strong sparking limits the capacitor, which is attached to the outside of the ignition distributor. After a certain time, it is necessary to adjust the gap between the contacts or replace them. In order to limit maintenance, transistorized ignition systems have been introduced that do not have moving breaker contacts.
