Example 1
The spark discharge occurs at a high voltage, the duration of the discharge is short.
The cause of the malfunction is the spark gap is too large.
Example 2
The spark discharge occurs at a low voltage, the trailing edge is gentle, and the duration of the discharge is long. The final phase of the discharge is distorted. With this form of signal, misfiring of the working mixture is possible.
The cause of the malfunction is the spark gap is too small.
Example 3
The spark discharge occurs at a low voltage, the trailing edge is gentle, and the duration of the discharge is long. However, no signal distortion is observed.
The cause of the malfunction is the spark gap is clogged.
Example 4
The spark discharge occurs at a high voltage, the duration of the discharge is short. The difference between this waveform and the waveform in example 1 is very difficult to catch.
The cause of the malfunction is the high voltage wire is frayed, the contact of the tips is broken.
Example 5
There are no vibrations in the damping region.
The cause of the malfunction is the short circuit of the turns in the ignition coil.
