Numerical Analysis on Soot Reduction Based on Butanol Blended with Gas Oil


In the present study, the effect of butanol blend fuel on soot reduction was investigated in a diesel engine theoretically as well as experimentally. The concept of the threshold sooting index (TSI), which has been proposed as the sooting tendency in fuel flames, was incorporated into the soot formation model in KIVA-3V code. The soot emission trend obtained in the experiments was clearly shown in the present simulation by considering the characteristic TSI values for butanol and gas oil as well as the alcohol blend ratio.ブタノール混合軽油の排気特性に及ぼすブタノール混合割合および排気再循環比の影響を実験的に追究し,ブタノール混合軽油のすす低減効果をKIVA-3Vを用いて数値解析することによって,すす低減はブタノールのすす生成性向TSIの低さに基づくものと,着火遅れの増加に基づく予混合化促進によることを明らかにした.
