| Outline of Final Research Achievements |
Non equilibrium plasmas are receiving special interest to improve thermal efficiency of the internal combustion engines because of its potential on volumetric ignition achievement and the use of alternative chemical reactions. Physics of the non-equilibrium discharge formation for the volumetric ignition and enhancement of ignition and combustion by the irradiation of the plasma to the air/fuel mixtures were studied. The effect of spatial plasma distribution to the morphology of the successive discharge and the shortening of ignition delay on compression ignition were examined. It was found the formaldehyde is the plausible candidate which enhances the compression ignition of methane/air mixture based on the mass spectral analysis and chemical kinetic simulations.
