secondary-simultaneous ignition will be shown as Figure 4-8.

Fig. 4-9 below shows the valid and invalid ignition waveforms. Under
the working status of valid ignition, the breakdown voltage and spark
voltage are higher because the cylinder is filled with fresh
combustible mixture gas, which has a lower ionization level and vice
versa.
