Abstract

The purpose of this study is to investigate the effect of ethanol content on the emission of nanosized particles from a diesel-ethanol blended fuel engine. The engine combustion and exhaust emission characteristics of a singlecylinder diesel engine were analyzed using an emission analyzer and an SMPS(scanning mobility particle sizer). The analysis revealed that soot emission increased with the ignition delay. When the ignition delay was fixed, an increase in the ethanol content caused a decrease in the soot emission. With an increase in the ethanol blending ratio, the number concentration and mass distribution of nanosized particles generally decreased. However, for 30% ethanol blending, large particles were observed because of the agglomeration of soot particles, and consequently, the particle mass increased.

본 연구의 목적은 디젤-에탄올 혼합연료로 운전되는 디젤엔진에서 에탄올 혼합비율이 나노 크기 입자 배출 특성에 미치는 영향을 분석하는 것이다. 엔진의 연소 및 배기 배출물 특성은 배기량 373cc 의 단기통 디젤엔진과 배기 배출물 측정 장치, SMPS 를 이용하여 실험하였다. 그을음(soot) 배출은 착화지연 기간이 길어짐에 따라 증가하였다. 에탄올 혼합비율이 증가함에 따라 나노 입자의 총 개수 및 질량은 대체로 감소하는 경향을 나타냈다. 그러나 에탄올이 30% 혼합되었을 때 그을음(soot) 입자의 응결로 인해 큰 입자의 수 분포가 증가하였으며, 질량 또한 크게 증가하였다.
