Abstract

An experimental study was performed in order to compare with the case of using pure diesel the characteristics of combustion pressure and exhaust emissions when the engine speed was changed in a CRDI 4-cylinder diesel engine using biodiesel( Canola oil) blended and pure diesel fuel. As a results, the combustion pressure was decreased with increasing biodiesel blended rate when engine speed was 1,000, 1,500, 2000(rpm). but the combustion pressure of the engine speed 2,500rpm was increased with increasing biodiesel blended rate. The emission results show, that CO was decreased with increasing biodiesel blended rate and engine speed. The emission of $CO_2$, NOx, were increased with increasing biodiesel blended rate and engine speed.

본 연구는 4실린더 커먼레일 디젤기관에서 식물성 바이오 연료인 카롤라유(Canola oil)와 디젤연료를 혼합하여 사용하였을 때 바이오디젤 혼합율과 엔진 회전수 변화에 따른 연소 및 배기 배출물 특성을 조사하기 위하여 실험을 수행하였다. 실험 결과에 의하면 엔진 회전수 1,000, 1,500, 2,000(rpm)에서 연소 압력은 바이오디젤 혼합율이 증가할수록 감소하고, 2500rpm에서는 바이오디젤 혼합율이 증가할수록 증가 하였으며, 열 발생율은 바이오디젤 혼합율이 증가 할수록 모두 증가하였다. 연료 소비율은 바이오디젤 혼합율이 증가할수록 엔진 회전수가 상승할수록 증가하였다. CO 배출물은 엔진 회전수가 상승할수록, 바이오디젤 혼합율이 증가할수록 감소하였다. $CO_2$, NOx, 배출물은 엔진 회전수가 상승할수록 바이오디젤 혼합율이 증가할수록 증가하였다.
