柴油机排放颗粒物不仅污染其他物体,而且由于它是致癌物质苯丙荜的载体,因而对人体健康形成威胁,故国外对于柴油机排放颗粒物的限制日趋严格,美国1987年排放标准中限制值为0.26克/公里。为确保柴油机市场,很多厂商、大学及研究机构对此做了大量研究试验工作。 柴油机排放颗粒物的净化技术是近十年来,特别是近五年迅速发展起来的新技术,为适应我国环境保护的要求,现已开始充分重视并广泛开展了此项研究。 本文综述国内、外近几年来在该技术领域内的最新成就及发展趋势,并做了评述,以供参考。
Diesel emissions of particulate matter not only pollute other objects, but also because it is a carrier of carcinogen phenylpropisol, which pose a threat to human health, so the foreign emission control of diesel particulate matter increasingly stringent restrictions on emissions in the United States in 1987 the value of 0.26 g / Km. To ensure that the diesel engine market, many manufacturers, universities and research institutions have done a lot of research and experimental work. The purification technology of particulate matter emitted from diesel engines is a new technology developed rapidly in the past decade, especially in the recent five years. To meet the requirements of environmental protection in our country, attention has been devoted to this research. This article reviews the latest achievements and trends in the field of technology at home and abroad in recent years and makes comments for reference.
