Abstract	Non-equilibrated (non-thermal) plasma generated by short (ns), high-voltage (kV) pulses has attractive electron characteristics that fundamentally and favorably alter pre-combustion chemistry and physics [1]. This technology has been demonstrated in applications for airborne engines, including pulse detonation engines [2], in collaborative studies with Nissan in applications for internal combustion engines [3], as well as for more fundamental studies [4]. We report recent studies where two compact power modulator systems are used to produce non-equilibrium plasma in the transient, formative phase of an arc, and are applied to ignition and combustion (transient plasma ignition or TPI) in a constant volume reactor. In this work, ignition delays, a key parameter in the application to pulse detonation engines, were measured in transient plasma ignited C2H4-air in a constant volume reactor at atmospheric pressure. Two compact power modulators were used; a 12 ns SCR-switched magnetic compression based pulse generator and an 85 ns pseudospark switched line-type pulse generator. The results show that despite the difference in energy delivered (70 mJ vs. 400 mJ), both systems achieve similar ignition delays across a broad range of equivalence ratios, and produce ignition delays up to two times shorter than with traditional spark ignition, confirming previous results obtained in an flowing system (pulse detonation engine) [5]. The results indicate that lower energy, more compact power modulators may be used for this application.
