The ignition system works in cooperation with the injection system, namely: all sensors and probes that are intended for the ignition system also affect the ignition system, and above all at the moment of ignition. An ignition timing sensor installed in the region of each cylinder provides information to the system controller about the position of the crankshaft journal at the moment of ignition, so that the ignition timing can be determined accordingly.
The ignition distributor is installed at the end of the cylinder head and is driven by a camshaft. Like other ignition distributors in the engines of the company «Volkswagen», the ignition distributor has a Hall sensor, that is, the ignition impulses are transmitted to the candles by means of impulses from the ignition distributor rotor to the contacts.
The battery voltage, after being converted in the ignition transformer, is fed to the impulse sender of the ignition distributor, and from there through the spark plug cables to the spark plugs. Cylinder sequence: 1-5-3-6-2-4.
The middle cable of the ignition distributor conducts a strong current, and this current through the rotor of the ignition distributor, which moves alternately through six segments in the cover that separates the breaker from the ignition distributor, and through the high-voltage cable enters the corresponding spark plugs.
The ignition is set electronically using the engine's electrical equipment, that is, the distributor itself does not have any centrifugal mechanism or a vacuum ignition timing controller.
