TFZ ignition system

The TFZ ignition system works on the same principle as the EZL ignition system, with the following differences.

In the TFZ ignition system, the ignition timing is determined by a sensor installed in the ignition distributor. This design makes it possible to set the initial ignition timing by turning the housing of the ignition distributor relative to the distributor shaft.

When the engine is running, the ignition timing is partly controlled by an electronic device, and partly by a vacuum regulator installed on the ignition distributor. The electronic control device increases the ignition timing with increasing engine speed, and the vacuum regulator - with increasing load.

On models with a carburetor, when the engine warms up, the thermal switch and control valve change the ignition timing through the vacuum correction unit.
