How many Sparks does an ignition coil generate?
Within 3.5 milliseconds, each ignition coil has to generate three sparks. Each spark lasts approximately 0.5 ms. This requires a powerful ignition system, where the charging time for the coil should be very short. Charging time in this situation is only 0.7 ms. The first two sparks are “canceled” which results in energy remaining in the coil.
