1 前言改善大气环境的当务之急是降低车用柴油机的排放,不仅要降低CO_2的排放量,而且特别要降低柴油机NO_x 和颗粒的排放量。现就降低颗粒排放的后处理技术介绍如下。柴油机排出的颗粒大致可分为碳颗粒和SOF(可溶性有机物)的焦油状成分(燃油和机油未燃烧生成物,可溶于有机溶剂),作为后处理技术,因处理对象的不同而异。
1 Introduction The immediate priority of improving the atmospheric environment is to reduce the emission of vehicle diesel engines, not only to reduce the emission of CO 2, but also to reduce the emission of diesel engines NO x and particulates in particular. Now on the reduction of particulate emissions after treatment technology are as follows. Diesel exhaust particles can be roughly divided into carbon particles and SOF (soluble organic matter) tarry components (fuel and oil unburned products, soluble in organic solvents), as a post-processing technology, depending on the treatment of different objects.
