The proposed research is part of a research study on the development of a diesel engine emissions reduction system with enhanced performance by utilisation of hydrogen produced on-board by exhaust gas fuel reforming. The research is motivated by the requirement of diesel engines to meet future emission regulations and by the potential of on-board exhaust gas fuel reforming to provide a way of improving diesel combustion and emissions as well as increasing the efficiency of diesel engine aftertreatment devices.The system targets are to achieve HC, CO and particulate matter (PM) emissions reduction of >90% using a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF), respectively, and NOx reduction of >70% using lean NOx catalyst technology (HC-SCR or NH3-SCR or NOx trap). The system will have to be cost effective (i.e. use of base metal catalyst or reduced precious metal catalyst content) and should operate without the need of specific engine map development.Specifically, the purpose of the present proposal is to extent the scientific knowledge on PM aftertreatment assisted by reformate addition that will allow successful integration of the DPF and reforming technologies.The study unfolds into two main parts: i) investigation of the use of reformate to promote the soot oxidation and hence improve the DPF regeneration at low exhaust gas temperatures (Brunel University) and ii) investigation of the improvement of DPF regeneration by soot oxidation with NO2 achieved through promotion of the low temperature NO to NO2 conversion rates in a DOC situated upstream of the DPF by addition of small quantities of reformate (University of Birmingham).By extending the understanding of the fundamental processes occurring during NO oxidation and filter regeneration, new catalysts and catalytic systems will be designed and guidelines for the further stages of the research programme towards a full working diesel engine - fuel reformer - aftertreatment system will be developed.

拟议的研究是一项研究的一部分，该研究旨在开发一种柴油发动机减排系统，通过利用废气燃料重整产生的氢气来提高性能。该研究的动机是柴油机满足未来排放法规的要求，以及车载废气燃料重整的潜力，以提供改善柴油机燃烧和排放以及提高柴油机后处理装置效率的方法。分别使用柴油氧化催化剂（DOC）和柴油颗粒过滤器（DPF）使CO和颗粒物（PM）排放减少>90%，使用贫NOx催化剂技术（HC-SCR或NH3-SCR或NOx捕集器），NOx还原>70%。该系统必须具有成本效益（即使用贱金属催化剂或减少贵金属催化剂含量），并且应在不需要特定发动机图谱开发的情况下运行。具体而言，本提案的目的是扩展关于通过重整油添加辅助的PM后处理的科学知识，这将允许DPF和重整技术的成功集成。本研究分为两个主要部分：i）研究使用重整产物来促进碳烟氧化，从而改善低废气温度下的DPF再生（Brunel University）和ii）研究通过添加少量重整产物来促进位于DPF上游的DOC中的低温NO至NO2转化率，通过用NO2进行烟灰氧化来实现DPF再生的改进通过扩大对NO氧化和过滤器再生过程中发生的基本过程的理解，将设计新的催化剂和催化系统，并将为研究计划的进一步阶段制定指导方针，以实现全面工作的柴油发动机-燃料重整器-后处理系统。
