Only on carburetor engines without the catalyst the ordinary distributor of ignition which regulates the ignition moment under the influence of centrifugal force and depression which join depending on number of turns and engine loading is established. At increase in number of turns of the engine centrifugal грузики in the carburetor move under the influence of centrifugal force outside of, against force of a small returnable spring, turn thus an adjusting cam concerning a distributor shaft so earlier ignition is established. The vacuum device is connected to the carburetor the small pipeline. At high depression, earlier ignition is established, however is established back when the engine is under big loading.

The drive of the distributor of ignition is carried out from one of cam-shafts. On injector engines the moment of ignition is regulated by an electronic monitor to provide the best the fuel and air relation under all service conditions. These adjustments of ignition register in memory of a monitor. The monitor receives information, for example, duration of injection and position of the crankshaft and operates the key transistor, during the set moment. Adjustment of the moment of ignition is established on optimum value at engine start, at its warming up, idling, at acceleration and at movement nakaty.
