CDI means
Capacitor Discharging Ignition, which already describes the principle of work quite well.
«In this experiment, the technical difficulty is getting all the different
capacitor discharges to work at the right times with the right currents,» Degnan says, «and getting all the diagnostic equipment to work, because if you can't measure it, you don't know what happened.»
