- Abstract
- The effect of air/fuel ratio on combustion characteristics was investigated in a compression ignition engine fueled with biodiesel. For investigating the effect of biodiesel air/fuel ratio on combustion characteristics, the experiments were performed at various equivalence ratios and 120㎫ of injection pressure. In addition, lambda meter were equipped to measure air/fuel ratio, which is varied from 0.6 to 1.0 as using various EGR ratio. The results were compared with those results without EGR. For analyzing exhaust emission characteristics, nitrogen oxidies(NOx), hydrocarbon(HC), and carbon monoxide(CO) are measured under the various air/fuel ratios. The experimental results show that NOx emission gradually decreased according to the decrease of equivalence ratio, and HC and soot emissions significantly increased as advanced injection timing. The soot and HC emissions generally decreased and NOx emission was almost zero level according to retarded injection timing cases.
