Ignition
1 - ignition module (N 152); 2 - output stage of the high power ignition module - ignition coil (N 157); 3 - resistor (0.6 to 1.4 kOhm); 4 - connector; 5 - three-pole connector of the Hall sensor; 6 - shielding cover; 7 - distributor cover; 8 - distributor slider; 9 - dustproof seal; 10 – a bolt with an internal hexagon (M= 65 Nm); 11 - distributor with Hall sensor; 12 - washer: 13 - bolt (M = 20 Nm; M affects the function of the knock sensor); 14 - knock sensor G 61); 15 - two-pole knock sensor connector; 16 - spark plug (M = 25 Nm); 17 - connector on the candle (from 4 to 6 kOhm); 18 - high-voltage ignition wire; 19 - bracket
Electronic ignition consists of:
- control unit 1 AV, which calculates the angle of connection, the moment of ignition;
- distributor with Hall sensor;
- ignition module;
- high voltage ignition wires;
- spark plugs;
- details related to them.
For the ignition control system, the input information consists of basic and corrective information.
Basic information
- engine speed;
- the amount of incoming air;
- pressure and temperature of the incoming air.
Corrective Information
- detonation signal;
- incoming air temperature;
- coolant temperature;
- throttle potentiometer signal;
- battery voltage.
Functions of the ignition system
- ignition timing adjustment;
- calculation of the angle of ignition;
- idling stabilization;
- selective knock control.
The calculation of the ignition moment is carried out based on the characteristics stored in the memory of the control unit. When starting the engine, a fixed ignition timing is applied. The transition to normal operation occurs as soon as the first cylinder, as well as the three remaining ones, are recognized by the Hall sensor and coordinated accordingly.
