Explain why dwell time is important to ignition system operation.

To determine

The reason for the importance of dwell time to ignition system operation.

Explanation

Due to the presence of reactance, the ignition coil primary takes some time to get fully magnetized. So the current flow in the primary winding for some time before the spark plug can be fired. This time period is known as the dwell time.

The ignition coil primary will get saturated only if the dwell time is long enough to allow maximum current to flow through the primary winding. If the dwell time is not sufficient, then the ignition coil will not get saturated and it will produce less voltage...
