摘要

对柴油机燃用生物柴油-0号柴油混合燃料的NO_x和Soot排放特性进行了仿真研究。在柴油机参数不作任何改变的情况下燃用体积分数分别为10%，20%，30%，40%和50%的生物柴油混合燃料，与原机的NO_x和Soot排放特性进行对比。研究表明：随着混合燃料中生物柴油体积分数的增加，柴油机Soot排放降低，NO_x排放增大。EGR的引入使柴油机NO_x排放降低，同时也使Soot排放增加。在1 800 r/min中低负荷工况下，大比例生物柴油0号柴油混合燃料应用于柴油机时，可通过调节EGR率使得柴油机NO_x和Soot排放都控制到与原机相当。

Abstract

The NO_xand soot emissions of diesel engine fueled with biodiesel and 0# diesel blended fuel were simulated and analyzed. Blended fuels with the biodiesel volume fractions of 10%, 20%, 30%, 40% and 50% were fueled on the same engine and their NO_xand soot emissions were compared with those fueled with pure diesel. The results showed that soot emission reduced and NO_xemission increased with the increase of biodiesel volume fraction. Under medium and low load at 1 800 r/min, the NO_xand soot emissions of high concentration biodiesel and 0#diesel could be adjusted to the original level by adjusting the EGR rate.
