11.6.4.3. Controller of electronic ignition

In system of ignition of the engine 3313 the controller of electronic ignition of the M3313 type which is located on a front board behind a motor-compartment partition is used.

View of the controller from a motor-compartment

1 – arm;
2 – controller;
3 – protective cover;
4 – cowl loop;
5 – screen wiper motor-reducer arm;
6 – welded bolt of an arm;
7 – nut and washers of fastening of the controller;
8 – vacuum tube;
9 – the socket is shtekerny

The controller provides:

  – management of an ignition advancing corner according to characteristics of the heated-up and not heated-up engine depending on tension on an entrance from temperature sensor for various temperatures of cooling liquid;
  – continuous sparking after giving on it of supply voltage, entrance signals and relative pressure according to its technical characteristic;
  – formation of impulses of current and value of the switched current through primary windings of coils of ignition (gap currents etc.).

The controller is not maintainable and in case of failure is subject to replacement. If in search result of malfunctions the validity of peripheral elements is confirmed, but MPSZ does not work, the controller is faulty.

Moment of an inhaling of nuts of fastening of the controller of 4,1-7,81 N · m (0,4–0,8 kgfs · м).

Purpose of conclusions of the controller is given in the table.
