The secondary winding of the ignition coil is connected to the high-voltage wires and spark plugs. The induced voltage in the ignition coil causes a spark to break down first between the distributor pin and the high-voltage wire of the corresponding cylinder, then between the electrodes of the spark plug in the cylinder.
When the breaker contacts open, small sparks occur between them, which eventually burn the plane of the contacts. Very strong sparking is limited by a capacitor, which is attached to the outside of the ignition distributor. After a certain time, it is necessary to adjust the break between the contacts or replace them. In order to limit maintenance, transistor ignition systems have been introduced, in which there are no moving contacts of the breaker.
