Abstract

<p>The promotion effect on ethanol fermentation was investigated by adding Kakkonto or Bofutsushosan residues which are waste materials from Kampo industry. Moreover, hydrous bioethanol was obtained by distillated from fermented liquid with Kakkonto or Bofutsushosan residues. These fuels were supplied to gasoline engine, and exhaust gas was evaluated. The ethanol fermentation was promoted by adding Bofutsushosan residue compared with additive-free medium. However, Kakkonto residue had not promotion effect. On the other hand, concentration of carbon monoxide and hydrocarbon exhaust gas by distilled ethanol including Kakkonto component were lower than gasoline or reagent ethanol.</p>
