低温等离子体降低柴油机排放的研究进展

摘要

This paper describes briefly various after-treatment technologies in diesel engines, and application difficulties of DPF and SCR are included. The main principle of D/I NTP is analyzed in detail. It introduces some research progress and development tendency on non-thermal plasma to reduce diesel emissions. It is indicated that the microscopic mechanism of D/I NTP system to reduce PM emission and DPF regeneration will be key research in the future.%简要介绍了当前柴油机排气后处理所采用的DPF和SCR技术,并指出了其应用难点.详细分析了两种低温等离子体技术各自的技术特点,阐述了D/INTP技术在降低柴油机有害排放方面最新的研究进展及发展趋势,指出对D/INTP系统分解柴油机排气中PM、再生DPF的微观机理进行分析将成为今后研究的重点.
