控制柴油机排放的关键在于控制NOX和PM的排放,主要依赖于柴油品质的提高和后处理技术的发展。文中重点分析了柴油性质中硫、芳烃、十六烷值和馏程对NOX和PM排放的影响,探讨了当前用于控制NOX和PM的主要后处理技术。 The key to controlling diesel emissions is to control NOx and PM emissions, mainly relying on the improvement of diesel quality and the development of aftertreatment technologies. In this paper, the effects of sulfur, aromatics, cetane number and distillation range on NOX and PM emissions in diesel fuel are analyzed emphatically, and the main post-treatment technologies currently used to control NOx and PM are discussed.
