Ignition Voltage Rate-of-Rise

Posted on: Friday October 7, 2016

Ignition Voltage Rate-of-Rise There are a lot of myths associated with ignition systems and the fast voltage rise before spark breakdown with CD ignition is one of them. The voltage rate-of-rise is determined primarily by the coil, not whether it is used inductively or with a capacitor discharging through it. The difference in the voltage rate-of-rise only becomes noticeable when a shunt resistance is applied across the spark gap and then the CDI rate-of-rise doesn't slow down nearly...

Ignition Voltage Overshoot

Posted on: Friday February 5, 2016

Ignition Voltage Overshoot by Fred Winterburn, January 2016 It's commonly written that the voltage required to initiate a spark with an ignition system is dependent on the width of the plug gap and conditions at the plug gap including electrode shape, polarity, electrode temperature, and density of the fuel/air between the electrodes. There are probably other factors as well that determine the threshold voltage required. While all of this is true, none of the commonly written explanat...

Condenser Action And More

Posted on: Sunday October 2, 2016

Condenser action with added information pertaining to spark duration Fred Winterburn, December 2015 An ignition coil used inductively to create a spark does so by a process known as self-induction. When a current flowing in an inductor is suddenly interrupted, the voltage rises higher than the voltage difference that was required to move the current in the first place. To think of this in terms that make it easier to understand, consider the following water hammer analogy. If a column of w...
