本文指出大气污染问题的严重性及带来的巨大经济损失，其中装有内燃机的运输工具的排放物已占到总污染物的首位。文中列出了柴油机有害排放物的具体构成及各种有害成分的危害性，并列出了俄罗斯、欧共体、美国、德国的现用及远景的排放限度标准。提出了降低柴油机有害排放物应重视外部系统的发展及相应的具体办法。

This paper points out the seriousness of the problem of air pollution and the huge economic losses brought by it. In particular, emissions from transport vehicles equipped with internal combustion engines account for the largest proportion of total pollutants. The paper lists the specific composition of harmful emissions of diesel engines and the dangers of various harmful components, and lists the current and future emission limits of Russia, the European Community, the United States, Germany. Proposed to reduce the harmful emissions of diesel engines should pay attention to the development of external systems and the corresponding specific measures.
