生物柴油是一种环境友好的柴油机替代燃料，因为它可以减少可控和非可控排放。然而，大多数研究人员观察到，与石油柴油相比，生物柴油的NOx排放量显著增加。这一增加的确切原因尚不清楚；然而，研究人员认为，燃料性质已被证明影响NOx的排放。本文综述了燃料性质和组成对生物柴油发动机NOx排放的影响。这篇论文分为三个部分。第一部分是关于NOx的形成机制。在下一节中，讨论了生物柴油NOx排放增加的原因。在此基础上，综述了组成和燃料性质对生物柴油发动机NOx排放的影响。最后，总结了关于这一问题的一些一般性结论，并指出了进一步的研究方向。
Biodiesel has proved to be an environment friendly alternative fuel for diesel engine because it can alleviate regulated and unregulated exhaust emissions. However, most researchers have observed a significant increase in NOxemissions with biodiesel when compared to petrodiesel. The exact cause of this increase is still unclear; however, researchers believe that the fuel properties have been shown to effect the emissions of NOx. The present work reviews the effect of fuel properties and composition on NOxemissions from biodiesel fuelled engines. The paper is organised in three sections. The first section deals with the NOxformation mechanisms. In the following section, the reasons for increased NOxemissions of biodiesel fuel are discussed. After this, the influence of composition and fuel properties on NOxemissions from biodiesel fuelled engines has been reviewed. Finally, some general conclusions concerning this problem are summarised and further researches are pointed out.
