摘要
随着全球对环境保护标准的提升,柴油机排放的控制尤其受到关注。特别是轻型柴油机的尾气排放,其中的氮氧化物和颗粒物成为主要的环境污染源。本文综述了柴油机尾气的主要成分、机内控制技术以及尾气后处理技术,包括选择性催化还原、颗粒捕集器和氧化催化转化器。此外,还探讨了现代柴油机尾气处理技术的发展趋势和挑战,为未来尾气处理技术的优化提供了理论基础和应用前景。
With the global enhancement of environmental protection standards,the control of diesel engine emissions has become a focal point,especially concerning the exhaust emissions from light-duty diesel engines.Nitrogen oxides(NO x)and particulate matter(PM)in these emissions have become major sources of environmental pollution.This paper reviews the main components of diesel engine exhaust,in-cylinder control technologies,and post-treatment technologies,including selective catalytic reduction(SCR),particulate filters,and oxidation catalysts.Furthermore,it discusses the development trends and challenges of modern diesel engine exhaust treatment technologies,providing a theoretical foundation and application prospects for optimizing future exhaust treatment technologies.
