Abstract

Our environment is faced with serious problems related to the air pollution from diesel engines in these days. In particular, the exhaust emissions of agricultural diesel engines are recognized main cause which influenced environment strongly. In this study, the potential possibility of biodiesel fuel was investigated as an alternative fuel for a naturally aspirated agricultural D.I. diesel engine. The smoke emission of biodiesel fuel was reduced remarkably in comparison with diesel fuel, that is, it was reduced approximately 50% at 2500 rpm, full load. But, power, torque and brake specific energy consumption didn't have large differences. But, NOx emission of biodiesel fuel was increased compared with commercial diesel fuel. Also, the effects of exhaust gas recirculation (EGR) on the characteristics of NOx emission has been investigated. It was found that simultaneous reduction of smoke and NOx was achieved with biodiesel fuel (20vol-%) and cooled EGR method($5{\sim}15%$) in an agricultural D.I. diesel engine.
