Abstract:

Apparatus and method for a plasma discharge for ignition in an internal combustion engine. A digital electronic system controls ignition performance and can provide an ignition discharge throughout an entire power stroke of a piston in a cylinder. The discharge can be controlled by a signal from a conventional distributor, crank trigger or other source. Controllable discharge of a capacitor occurs through the primary winding of an ignition coil. In addition, the capacitor may be both discharged and recharged in an oscillatory manner through the primary of the ignition coil. Such oscillatory discharging and recharging of the capacitor results in energy being delivered to the spark plug during both discharge and recharge cycles, thereby resulting in the delivery of discharge energy to the spark plug on a substantially continuous basis.
