Abstract

The using of diesel engine will be increased in the world for fuel economy. But diesel engine emits harmful emissions such as much NOx, smoke etc. In this study, experiments were performed to investigate the spray characteristics of diesel spray in a common-rail system according to fuel temperature, injection pressure, injection period and fuel viscosity etc. using a high speed video camera. Diesel oil has different spray patten due to injection pressure and injection period in a common-rail system. A Filter pressure was influenced by fuel temperature which was turned to fuel viscosity related to a fluid flowing. The effect of the bio-diesel fuel mixing ratio on the spray and atomization characteristics was also investigated at various experimental conditions. It shows that the droplet atomization characteristics of bio-diesel fuel showed deteriorated results as the mixing ratio of biodiesel increased because of the high viscosity.

디젤기관은 세계적으로 연료의 경제성 때문에 사용이 증가할 것이다. 그러나 NOx, 매연 등과 같은 배기가스를 배출한다. 본 연구는 커먼레일 연료분사 시스템에서, 연료온도, 분사 압력, 분사시간, 연료 점성에 따른 분무 특성을 실험하였다. 커먼레일 시스템에서, 디젤 연료는 분사 압력, 분사 시간에 따라 분무 형상이 다르다. 필터 압력은 연료 유동과 관련이 있는 연료 점성을 변화시키는 연료 온도에 영향을 받는다. 분무와 무화특성에 미치는 바이오 디젤 연료의 혼합율의 영향에 대해 많은 실험 조건에서 실험하였다. 바이오디젤 연료의 미립화 특성은 바이오 디젤 혼합비율이 증가하면 높은 점성 때문에 악화되는 것을 알았다.
