1 mar 2021 · The period when the ignition system applies an electric current to the ignition coil’s primary winding is often referred to as the “dwell period” or “dwell time”. With modern ignition systems, the dwell period is controlled electronically so there is always sufficient time to fully charge the coil.

This article will explain how the terms “dwell” and “dwell angle” apply to modern inductive ignition systems, but note that “dwell angle” has largely been replaced by the term “dwell time”, which as a practical matter, has the same meaning as the older term.
Dwell, or ‘dwell time’ in ignition systems refers to the period of time that the coil is turned on, ie that current is flowing through the primary winding and the magnetic field is building up in the coil.
21 lip 2021 · Ignition Dwell is the time that the ignition coil has to charge between firings and a Pertronix Electronic Conversion Kit improves control and never needs adjustment. Learn more about Ignition dwell and why it is important to performance.
The appropriate dwell time depends on the individual ignition coil’s design characteristics (primarily, inductance) and supply voltage. The lower the supply voltage, the longer the dwell time needed.
30 kwi 2018 · In a four-cylinder engine, the angle between each ignition cam lobe is 90° and the period of points closure or "DWELL" is usually a bit over 45° of distributor rotation. In a six-cylinder engine, the lobes are 60° apart and the dwell time is 30° to 35°.
Triggering is arranged so that the ignition coil is charged in sufficient time before the actual ignition point. This requires the formation of a dwell period (coil saturation time) in the ignition system.
