[연료 및 윤활유부문] 에멀젼 연료를 이용한 디젤엔진의 분무 및 배기특성 연구 = Spray Characteristics and Exhaust Emission Tests for a Diesel Engine Using Emulsified Fuels

다국어 초록 (Multilingual Abstract)

Experiments have been conducted to investigate the effects of emulsified fuels on the spray characteristics and exhaust emissions in a diesel engine. Four different fuels were examined; diesel, emulsified fuels with water contents which were varied with 13, 15, and 17%. Characteristics of fuel spray were measured by an optical method. PLLIF(planar liquid laser induced fluorescence)<br/>
Compared to diesel fuel, emulsified fuels which had relatively high kinematic viscosity showed smaller spray angle and longer spray tip penetration. The Qualitative droplet distributions of emulsified fuels showed. worse atomization process than that of diesel fuel.<br/>
As the water contents were increased. PM and NOx could be reduced simultaneously. It was specially noted that the emulsified fuel with 17% water content was obtained best reducing rates, NOx 30% and PM 40%.<br/>
