中国将进入低氮经济时代。随着大气中氮氧化物的含量越来越高,氮氧化物对环境和人类健康的危害越来越严重。国家环保总局和发改委的官员近期在不同的场合都曾公开表态,“十二五”期间,氮氧化物(NO_X)将纳入大气污染物排放总量控制体系。我国的氮氧化物的排放总量中约30%来自于机动车排放的尾气,因此机动车尾气将成为氮减排的重要控制对象。与此相呼应的是,机动车尾气排放标准即将升级到国Ⅳ阶段。机动车实现氮减排和排放标准升级到国Ⅳ阶段所催生的柴油机动车尾气后处理市场商机巨大。根据我们对国内主要商用车生产企业、科研院所的技术专家的走访,预计重型柴油机动车实现氮减排和升级到国Ⅳ阶段排放标准的最优技术路线是高压共轨+SCR,中型、轻型、小型
China will enter a low-nitrogen economy. As the content of nitrogen oxides in the atmosphere becomes higher and higher, the harm of nitrogen oxides to the environment and human health is more and more serious. Officials of the State Environmental Protection Administration and the NDRC recently publicly stated on different occasions that during the “12th Five-Year Plan,” nitrogen oxides (NOx) will be included in the total air pollutant emission control system. About 30% of China’s total nitrogen oxide emissions come from motor vehicle emissions, so vehicle exhaust will become an important control object of nitrogen emission reduction. In response, motor vehicle emission standards are about to be upgraded to the stage IV. Motor vehicles to achieve nitrogen emission reduction and emission standards upgrade to the stage Ⅳ national phase of the diesel motor vehicle exhaust aftertreatment market opportunities. According to our visit to major domestic manufacturers of commercial vehicles, research institutes and technical experts visit, it is estimated that heavy diesel vehicles to achieve nitrogen emission reduction and upgrade to the country Ⅳ stage emission standards, the best technology line is the high pressure common rail + SCR, medium, light Small
