Abstract

This paper describes the effect of canola biodiesel blended fuel on the combustion and emission characteristics in a four cylinder CRDI(Common-rail direct injection) diesel engine. In this study, using the biodiesel fuel(20%,40% of biodiesel-canola oil and 80%, 60% of ULSD(ultra low sulfur diesel) by volume ratio with change of engine speed and injection pressure. The experiment results of increasing biodiesel ratio fuel show that NOx emissions increased. However, soot emission were reduced BC fuels compared to ULSD. Soot emissions largely increased at low injection pressure.

본 논문은 카놀라 바이오디젤 혼합연료를 승용디젤엔진에 적용하였을 때 나타나는 연소 및 배기배출물 특성에 관한 연구이다. 본 연구에서는 카놀라 바이오디젤을 20%, 40%를 ULSD 80%, 60%와 체적비로 혼합한 혼합연료를 사용하여 ULSD 결과 데이터와 비교하였다. 엔진 회전속도, 엔진부하, 연료분사압력 변화를 실험변수로 사용하였으며. 카놀라 바이오 디젤의 혼합비가 증가 할수록 NOx 배출량은 증가하였지만, Soot 배출량은 감소하는 결과를 나타내었다. 또한 Soot 배출량은 낮은 연료분사압력에서 높은 배출량을 보였다.
