A Study on the Effects of the Swirl Flow on the Distribution of Soot in the D.I. Diesel Engine

스월 유동이 직분식 디젤엔진 내의 Soot 분포에 미치는 영향에 관한 연구

Abstract

Recently, many researches have been performed to improve performances of the combustion and emission in the D.I.Diesel engine. Especially reduction of the soot formation in tole combustion chamber is the essential to acquire the improvement of the emission performance. These emission of the diesel combustion is effected by the characteristics of air-fuel mixing. Thus, in this study, the distribution of soot in the diesel combustion is measured by LII(laser induced incandescence) and LIS(Laser induced scattering) method. From this experimental results, it is confirmed that the swirl flow intensified by SCV(swirl control valve) is effective on the reduction of soot in the combustion chamber.
