Improving surface characteristics of Porous medium reactor in diesel engine by Plasma technology.

ABSTRACT- Applying Porous Medium (PM) as a heat reactor in diesel engine has been considered as a promising concept to approach a near-zero emission system. It takes full advantage of PM geometry and material characteristics to perform homogeneous combustion, therefore reduces significantly emission under all operational conditions. The surface characteristic of PM plays a key role in fuel vaporization process inside the combustion chamber. This paper summarizes the results of our recent effort in applying plasma technology to improve its surface characteristic. The research activities focused on preventing reactor surface from forming, sticking of soot and unburned liquid fuel. It helped to increase specific area, energy recirculation efficiency and enhance vaporization ability of fuel during injection process. TECHNICAL PAPER- Porous medium (PM) was introduced as a reactor in Internal Combustion engine recently. With potential for homogeneous combustion under variable operational conditions, it is shown to be a key role for reducing NOx and soot emission from engine, especially for diesel engine. Many studies have focused on this novel concept to prove its advantages in supporting mixture formation and combustion processes. The dee
