详细综述了柴油机排放控制技术的最新发展现状。总结了柴油机颗粒的性质。回顾了将对过滤器的应用起重大作用的各种柴油机颗粒过滤器再生策略。阐述了过滤器的改型和耐久性问题。对柴油机的DeNO_x催化器、SCR(选择催化还原)、NO_x捕集器以及非热能等离子体等方法分别作了总结,并介绍了能同时降低NO_x和颗粒(PM)的系统。讨论了减少有毒废气排放的问题,还涉及了2000年美国和欧洲的所有有关重要会议的论文。

The latest development of diesel engine emission control technology is reviewed in detail. Summarized the nature of diesel particles. Reviewed various diesel particulate filter regeneration strategies that will play a major role in the application of the filter. Describes the filter modification and durability issues. The methods of DeNO_x catalytic converter, SCR (selective catalytic reduction), NO_x trap and nonthermal plasma of diesel engine are summarized respectively. The system which can reduce NO_x and PM simultaneously is introduced. Discussed the issue of reducing emissions of toxic fumes and also addressed all the major conferences in the United States and Europe in 2000.
