Outline of Final Research Achievements

We propose plasma-assisted combustion that is different from conventional combustion to reduce harmful exhaust emissions as well as carbon dioxide in this study. The purpose of this study is to investigate the relation between ignition and combustion and non-equilibrium plasma under the conditions from room temperature and atmospheric pressure to high temperature and pressure both physically and chemically. And then, fundamental phenomena were revealed to create a new research field of smart combustion and these findings were applied to heat power engines. The effect of microwave plasma on radical density and combustion, radical behavior and combustion characteristics in the process of laser ignition superimposed with non-equilibrium plasma, and the effect of microwave on wet ethanol combustion and chemical reaction were investigated. A propagating flame could be controlled spatially and temporally with microwave. As a result, the possibility of new combustion with microwave was found.
