      fueling with water-containing butanol diesel blends.

AB  - The manufacture of water-containing butanol diesel blends requires no excess 
      dehydration and surfactant addition. Therefore, compared with the manufacture of 
      conventional bio-alcohols, the energy consumption for the manufacture of 
      water-containing butanol diesel blends is reduced, and the costs are lowered. In 
      this study, we verified that using water-containing butanol diesel blends not 
      only solves the tradeoff problem between nitrogen oxides (NOx) and particulate 
      matter emissions from diesel engines, but it also reduces the emissions of 
      persistent organic pollutants (POPs), including polycyclic aromatic hydrocarbons, 
      polychlorinated dibenzo-p-dioxins and dibenzofurans, polychlorinated biphenyls, 
      polychlorinated diphenyl ethers, polybrominated dibenzo-p-dioxins and 
      dibenzofurans, polybrominated biphenyls and polybrominated diphenyl ethers. After 
      using blends of B2 with 10% and 20% water-containing butanol, the POP emission 
      factors were decreased by amounts in the range of 22.6%-42.3% and 38.0%-65.5% on 
      a mass basis, as well as 18.7%-78.1% and 51.0%-84.9% on a toxicity basis. The 
      addition of water-containing butanol introduced a lower content of aromatic 
      compounds and most importantly, lead to more complete combustion, thus resulting 
      in a great reduction in the POP emissions. Not only did the self-provided oxygen 
      of butanol promote complete oxidation but also the water content in butanol 
      diesel blends could cause a microexplosion mechanism, which provided a better 
      turbulence and well-mixed environment for complete combustion.
