초록

저온에서 경유의 파라핀 왁스 생성 및 침전현상은 차량의 저온성능에 악영향을 준다. 본 연구에서는 경유에 바이오디젤, 등유, 저온특성첨가제를 혼합한 연료에 대해 연료조성에 따른 담점, 필터막힘점, 유동점 변화를 분석하였고, 경유의 저온특성에 따른 차량의 저온성능에 대해 평가하였다. 경유는 유동성향상 첨가제(WAFI)와 등유유분의 혼합량이 증가할수록 저온특성이 개선되었으며, 바이오디젤 혼합량이 증가할수록 저온특성이 악화되었다. WAFI는 필터막힘점 개선에, 등유유분은 담점 개선에 효과적이었다. 차량의 저온성능에 대하여 필터막힘점과 유동점의 영향성은 확인하였으나, 담점은 큰 영향이 없었다. 필터막힘점은 차량에 대해 저온에서의 운행가능 한계를 반영하였다.

At low temperature, Wax build-up and settling can affect adversely the cold weather performance of the diesel vehicle. In this study, we test the cold properties of diesel by blending ratio of biodiesel, kerosene and WAFI. Also, we test the cold weather performance for diesel vehicle by fuel cold properties. Cold properties of diesel are improved by adding the WAFI, kerosene and get worse by adding the biodiesel. WAFI is effective to improve a cold filter plugging point(CFPP) and Kerosene is effective to improve a cloud point(CP). CFPP and pour point(PP) are related to cold weather performance of diesel vehicle but CP is unrelated. CFPP indicate a limit temperature of vehicle driving possibility.
