[디젤엔진부문] DME-경유 혼합연료의 기존 디젤엔진 성능 및 배기가스 특성

DME is a good alternative fuel for reduce the smoke to almost zero when used in a diesel engine while problems such as low lubricity and high compressibility exist. In the present study. single cylinder DI diesel engine was modified in order to application DME-diesel blended fuel. with a conventional pump-line-nozzle system. we used the DME-diesel blended fuel. which is consisted of DME 50% and diesel oil 50% by volume. The results showed that the torque and the power of the DME-diesel blended fuel was the same as that of pure diesel oil. and the brake thermal efficiency increased a little. Also. smoke emission was reduced a little. but NOx emission was increased.
