영문 초록

The using of diesel engine will be increased in the world for fuel economy. But diesel engine exhaust emission such as much NOx, smoke etc. In this study, Thís experiments were performed the spray characteristics of diesel spray in common-rail system according to fuel temperature, injection pressure, injector spray time and fuel viscosity etc. Diesel have different spray patten due to injection pressure and spray time in common-rail system. A Filter pressure is influenced by fuel temperature which is 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 show deteriorated results as the mixing ratio of biodiesel increased because of the high viscosity.
