摘要
随着我国汽车工业的快速发展和机动车拥有量的快速增长，汽车尾气污染给城市环境带来巨大的影响，由此引起的氮氧化物型污染有可能代替煤烟型污染成为城市主要大气污染源．目前国内各大城市机动车排气污染危害日益严重，一些城市潜在着发生光化学烟雾的危险，ＮＯｘ已经成为北京、广州、上海、武汉等一些城市的主要污染物，其它一些城市ＮＯｘ污染的严重程度也在提高．造成汽车尾气严重污染的原因主要是汽车工业落后、尾气控制水平低、排放标准宽、管理不严等．
Automotive emissions bring out serious influence on urban environment with the rapid development of automobile industry and the increase of vehicles population.NOx pollution become the major air pollution sources,instead that of coal.Transportationrelated air pollution problems are more and more serious in some Chinese big cities such as BeijingGuangzhouShanghai etc.And NOx has already being one of the chief pollutants in these cities.There are many reasons that cause the automotive exhaust pollution:The disadvantage in automobile industry;low level of exhausts control;loose emission standards and imperfection on management.Some suggestions on reducing automobile pollution are presented.
