A Study for Characteristics of Performances and Exhaust Emission on Blending Rates of Biodiesel Fuel in a Common-Rail Injection Diesel Engine

커먼레일 분사방식 디젤기관에서 바이오디젤유의 혼합율에 따른 성능 및 배기배출물 특성 연구

Our environment is faced with serious problems related to the air pollution from automobiles in these days. In particular, the exhaust emissions of diesel engine are recognized main cause which influenced environment strong. In this study, the potential possibility of biodiesel fuel was investigated as an alternative fuel for a naturally aspirated common rail diesel engine. The smoke emission of biodiesel fuel 30vol-%(max. content) was reduced in comparison with diesel fuel, that is, it was reduced approximately 60% at 4000rpm, full load. But, power, torque and brake specific energy consumption didn't have no large differences. But, NOx emission of biodiesel fuel was increased compared with commercial diesel fuel.
