摘要:生物柴油是由动植物油通过酯交换技术得到,作为一种无毒、可生物降解和可再生的发动机代用燃料,已受到越来越多的关注。本文论述了生物柴油对柴油机NOx排放影响的各项研究结果,从喷油时机、燃烧过程和分子结构等方面分析了生物柴油NOx排放增加的原因,并提出了重新调整发动机、改进燃料和排气后处理等解决措施。

Abstract: Biodiesel is a kind of fuel
consisting of the alkyl monoesters of fatty acid from vegetable oil or animal
fat.More and more attentions to biodiesel appears for it is used as an
alternative,nontoxic,biodegradable and renewable diesel fuel.The paper
discusses research results on effects of biodiesel fuels to diesel engine NOx
emissions,analyzes the reasons resulting in increase of NOx emissions in diesel
engine which fuels biodiesel in terms of injection timing,combustion and
molecular structures of biodiesel,and also provide solution like engine
adjustment,fuel improvement and after exhaust treatment.
Keywords: Biodiesel;NOx;Emission
