Ignition system — general information

The ignition system is designed to ignite the working mixture in the engine cylinders with a spark discharge, which must be created at a strictly defined moment.

On engines with a working volume of 1.1 dm³, a classic contact ignition system is installed, and on other engines, since 1985, only a contactless ignition system has been installed. Depending on the type of engine, either a transistorized ignition system is installed (TSZ), or electronic ignition system (ESC-II – Electronic Spark Control).

The transistor ignition system has centrifugal and vacuum ignition timing controls. In the electronic ignition system, the function of the ignition timing regulator is performed by an electronic unit located on the left pillar in the engine compartment.

Since September 1988 on engines with a displacement of 1.3 dm³ (46 kW/ 63 hp) a non-contact ignition system without an ignition distributor is installed.
