Operating principle
Ignition system contactless, constant efficiency, supplies a high voltage to the spark at all engine operating modes. The system includes a sensor-distributor with integrated Hall generator, a switch and a special ignition coil.

 | The principle of operation of the pulse generator Hall |
According to the semiconductor passes control current coming from the connecting wires "A" and "B". When the magnetic field "H" intersects a plane perpendicular poleprovodniku between electrodes "E" and "F" potential difference. This phenomenon is referred to as the Hall effect. Generator Hall sensor integrated in the Distribution. It consists of a stationary (magnetic barrier) and movable (rotor) elements. Magnetic barrier consists of a screen mounted on the permanent magnet and the Hall sensor or Hall IC chip placed against a magnet on a ceramic holder. The rotor has four teeth corresponding to the number of cylinders of the engine. When the rotor teeth pass through the gap between the magnet and a Hall sensor. When a tooth is in the gap, the magnetic field is deflected and the Hall effect sensor is interrupted. With his disappearance trigger the transistor becomes conductive and passes the primary current of the ignition coil. Upon exiting from the tooth gap reappears and the magnetic field of the primary current flow is terminated, which gives rise, as in the conventional ignition coil, high voltage going to the spark plugs. The width of each tooth corresponds to the angle of the cam, i.e. this angle remains unchanged and does not need to be adjusted. As usual sensor-distributor, electromagnetic sensor-distributor includes centrifugal and vacuum regulators.  | Not be replaced by a rotor sensor-distributor others with different resistance. |
