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.
