3.7.4. System of ignition

GENERAL INFORMATION

The system of ignition provides complete control over adjustment of a corner of an advancing of ignition. The electronic control unit defines an optimum angle of an advancing of ignition for this speed, temperature of the engine, the provision of a butterfly valve and depression in an inlet collector.

System of ignition with the ignition distributor

The system of ignition with the distributor of ignition is installed on all models, except models of 1998 of release. The system consists of the lock of ignition, the accumulator, the coil and the distributor of ignition, an electronic control unit, wires of high voltage and spark plugs.

System of ignition without ignition distributor (only models of 1998 of release)

This system consists of the ignition coil with a separate conclusion for each cylinder, and also the corresponding sensors and an electronic control unit.

PERFORMANCE ORDER

System of ignition with the ignition distributor

1. First of all, check connecting wires and reliability of connections. Check accumulator charging and the burned-through crossing points in a motive compartment.

2. Check existence of a spark on spark plugs.

3. If there is no spark, check a distributor cover, the runner and wires of high voltage.

4. Check presence of tension on a wire of the high voltage going from a secondary winding of the coil of ignition.

5. Check presence of tension on primary winding of the coil of ignition. Check resistance of windings of the coil of ignition.

6. Replace faulty elements.

System of ignition without ignition distributor

7. Check existence of a spark on each of spark plugs in turn.

8. Check resistance of windings of the coil of ignition. Check giving of tension for the ignition coil.

9. Check resistance of wires of high voltage. Replace faulty elements.
