DEFINITION

Classification: 123/406.57

And capacitor discharge for ignition spark energy:

(under subclass 406.56) Subject matter wherein the regulating means to vary spark ignition timing includes (a) a capacitor, (b) means to charge the capacitor, and (c) means to discharge the capacitor through an ignition coil primary winding thereby creating the high voltage used for combustible mixture ignition.
