Abstract
A plasma ignition system is described herein that can produce plasma ionization around a spark plug gap using a single power circuit for the spark and plasma ionization. The system results in fewer components and higher reliability, allowing the system to be more easily integrated with existing ignition circuitry or in new ignition system designs. The plasma ignition system adds a one-way current path between the primary and secondary windings of the high voltage transformer. This allows energy stored within the capacitor after the creation of the spark to flow out of the capacitor, across the one-way current path, and through the spark plug gap. Thus, the plasma ignition system provides a dramatically better ignition spark with relatively little increase in components. The system does so without requiring a secondary power supply circuit to generate the current for producing plasma ionization.
