| Outline of Final Research Achievements |
In this study, detailed two dimensional computational simulations of nanosecond pulsed DBD (dielectric barrier discharge) or pin-to-pin discharge in a lean methane/air mixture were conducted at 10 atm and 600 K for plasma assisted ignition in an internal combustion engine. The fundamental characteristics of the nanosecond pulsed discharge and the radical production processes in the typical operating condition of internal combustion engines are clarified with understanding the partition of electron energy for radical production. Lastly, the effect of plasma produced radicals on enhancement of ignition delay has been clearly shown.
