DME-바이오디젤 혼합연료의 DI 디젤엔진 성능 및 배기가스특성

Dimethyl Ether(DME) is a promising alternative fuel to reduce the smoke to almost zero level when used in diesel engines. However, neat DME may cause serious wear on the fuel injection system because of its low lubricity. In the present study, biodiesel which is another promising alternative fuel for diesel engine was used to improve the low lubricity of DME without deterioration of smoke-free characteristic of DME. Test results show that the DME-biodiesel blended fuels show almost zero smoke with good engine performance.
