4.1.1.8. Ignition system
THE GENERAL DATA

The system of ignition an accumulator room, transistor includes:

  – The distributor of ignition with the contactless gauge with the Hall converter;
  – The ignition coil;
  – The switchboard;
  – Spark plugs.

The distributor of ignition BOSCH

Characteristics of an advancing of ignition of the distributor of ignition BOSCH of the engine 1,3 д дм3

And – a centrifugal regulator,

In – a vacuum regulator

The prevention

During check at the stand (the ignition distributor is removed) values of number of turns of the engine are necessary for reducing by half. During check of the distributor established in the car, to size of an advancing of ignition it is necessary to add size of an initial corner of an advancing of ignition.


Characteristics of an advancing of ignition of the distributor of ignition BOSCH of the engine 1,6 д дм3

And – a centrifugal regulator,

In – a vacuum regulator

The prevention

During check at the stand (the ignition distributor is removed) values of number of turns of the engine are necessary for reducing by half. During check of the distributor established in the car, to size of an advancing of ignition it is necessary to add size of an initial corner of an advancing of ignition.


Characteristics of an advancing of ignition of the distributor of ignition BOSCH of the engine 2,0 дм3

And – a centrifugal regulator,

In – a vacuum regulator

The prevention

During check at the stand (the ignition distributor is removed) values of number of turns of the engine are necessary for reducing by half. During check of the distributor established in the car, to size of an advancing of ignition it is necessary to add size of an initial corner of an advancing of ignition.
