24 – the ignition coil;
25 – the plug 1 (–);
26 – the plug 15 (+);
27 – the plug 4;
28 – a protective cap of the coil of ignition

Contactless system of ignition of engine MS with one gauge of a detonation

1 – the gauge of frequency of rotation of a cranked shaft;
2 – the gauge of a corner of an advancing of ignition;
3 – the detonation gauge;
4 – a ljambda-probe;
5 – the frequency valve;
6 – the management block;
7 – connecting колодка the management block;
8 – a vacuum hose;
9 – connecting колодка the gauge of a corner of an advancing of ignition;
10 – connecting колодка the gauge of frequency of rotation of a cranked shaft;
11 – connecting колодка the detonation gauge;
12 – connecting колодка ljambda-probe heating;
13 – connecting колодка a ljambda-probe;
14 – an arm

On models of later release the contactless system of ignition FEI is established. This system is similar described above electronic system of ignition.

It is necessary to consider that on engines MS of later releases two gauges of a detonation are established. System FEI has "memory" in which the information on possible malfunctions of system of ignition contains. This information can be "read" by means of the special equipment for diagnosing.

At work with system FEI it is necessary to carry out following security measures:

– It is forbidden to touch conducting, to separate and connect it, to connect to conducting of system of ignition any equipment (including for diagnosing) at the working engine;
– If it is necessary to turn the engine a starter, to disconnect колодку from the ignition switchboard;
– To scroll a starter with the help зарядного devices it is supposed no more than 15 with at pressure not above 16,5 In;
– To wash the engine it is authorised only at the switched off ignition;
– At performance of welding works on the car the storage battery should be completely disconnected;
– Before car towage it is necessary to disconnect колодку from the ignition switchboard;
– It is forbidden to change бегунок the ignition distributor on бегунок other type. The corner of an advancing of ignition is set by the block of management of ignition, however it can be checked up and adjusted how has been described earlier (subsection 12.2.1.3 see), thus it is necessary to disconnect a vacuum hose from the block of management of ignition.
