7.4.4. Examples of oscillograms of a high voltage of faulty system of ignitionExample 1
The spark category occurs at big tension, duration of the category is small.
Cause of defect – the spark gap is too great.
Example 2
The spark category occurs at low tension, the back front – flat, duration of the category is great. The final phase of the category is distorted. At such form of a signal admissions of ignition of a working mix are possible.
Cause of defect – the spark gap is too small.
Example 3
The spark category occurs at low tension, the back front – flat, duration of the category is great. However thus it is not observed signal distortions.
Cause of defect – the spark gap is littered.
Example 4
The spark category occurs at big tension, duration of the category is small. A difference between this oscillogram and the oscillogram in an example 1 to catch very difficult.
Cause of defect – the wire of a high voltage frayed, contact of tips is broken.
Example 5
On a site of attenuation there are no fluctuations.
Cause of defect – short circuits of rounds in the ignition coil.
