Ignition type distributor (models) 40.3706, four-spark, unshielded with vacuum and centrifugal ignition timing controls. It has a built-in microelectronic sensor that generates voltage pulses when a slotted steel screen passes through its groove.
Switch type 36.3734 converts the control pulses of the sensor into current pulses in the primary winding of the ignition coil.
Ignition coil type 27.3705 - with an open magnetic circuit, oil-filled, sealed.
Spark plugs type FE65P.
Interference suppression tips type 31.3707.
Ignition switch type KZ81 (produced by Hungary) or 2108-3704005 (domestic production) with an anti-theft device and with a blocking against restarting the starter without first switching off the ignition. Some of the ignition switches can be equipped with an additional ignition relay type 111.3747.
