Contactless system of ignition




Device features

The system consists of a sensor-way valve with integrated proximity sensor, switch, and a high energy ignition coil.

Arrangement of elements of system of ignition TSZ

1 - Switch
2 - DLC

Location Switch (A) and DLC (B) of the ignition system TSZ

As usual sensor-distributor, electromagnetic sensor-distributor has centrifugal and vacuum regulators; Vacuum regulation is done by moving the screen with the teeth of the magnet assembly.

The switch is fixed on the mudguard wing to an aluminum lining, it provides cooling.

The switch is used to convert the signal of the pulse generator to the control signal.

It includes a device sensor signal allocator, the controller DC output amplifier consisting of the Darlington transistor and timer.

Ignition coil mounted near the control unit.


Pneumatic control system vacuum control ignition timing sensor-distributor ignition TSZ, depending on the temperature of the coolant in the engine is cold

When the coolant temperature is less than 60 ?� C thermostatic valve 5 is closed and the vacuum from the carburettor 1 enters the regulator 4 through the valve 3, thus providing an additional correction ignition angle 8-12 *.

A designation of color of wires:

  • ws - white
  • rt - Red
