摘要:由于柴油机具有热效率高、功率大、油耗低等优点,所以它在被广泛用于工业、农业、国防建设各领域。近年来,随着人们环境保护意识的增强,世界各国对柴油机废气排放的标准变得越来越严格。经过科学研究,柴油机排放物中CO和HC比汽油机少得多,NOx排放量与汽油机相近,但是排气微粒较多,这与柴油机燃烧机理有关。本文论述了柴油机微粒排放的主要净化措施,机内净化技术、机外净化技术,以及柴油机排放与控制技术现状及其发展趋势。关键词:柴油机;微粒排放;发展趋势
Abstract: The diesel engine is widely used in industry, agriculture, national defensing etc due to the advantages such like high heat efficiceny, powerful and low oil consumption ratio. In recent years, people are paying more attention to enviromental protection therefore many countries has set up stricter diesel engine exhaust standard. By scientific research it is found out the diesel engine exhaust less CO and HC than gasoline engine, similar NOx level but higher particles due to the combustion mechanism. This article studies the cleaning measures of particles of diesel engine exhaust, internal cleaning technology, external cleaning technology and controlling technology status quo and developing trend.
