This Small Business Innovation Research (SBIR) Phase II project proposes to develop an effective diesel particulate filter (DPF) that can be reliably regenerated with integral electrical heating elements. A fabrication process will also be developed that ensures economical manufacturability of the filter in high volumes. The greatest challenge in the design of reliable particulate filter and trap systems has been achieving adequate regeneration, or the oxidation (burning) of particulates that accumulate in the filter substrate diesel engine operation. The objectives of Phase II will include designing an actively regenerating filter structure, optimization of EC material for use in the DPF substrate, development of manufacturing processes suitable for scale up to volume production, construction of prototype DPF substrates, testing, and ultimately integration of the EC-integrated DPF into a functioning DPF system ready for field testing. The anticipated result of the Phase II project is an actively regenerating EC-integrated DPF prototype substrate suitable for field testing in the US EPA.s Voluntary Retrofit Program. The EC-integrated DPF will fulfill new emissions controls scheduled to take effect in 2007. There is presently a compelling need for a compact, simple-to-maintain, durable, and effective diesel particulate filter for both new and existing diesel- powered vehicles. The EC-integrated DPF could potentially reduce diesel particulate emissions by 9.5 million tons annually, preventing thousands of premature deaths due to respiratory illnesses, cancer and heart disease. .

这个小型企业创新研究(SBIR)第二阶段项目建议开发一种高效的柴油微粒过滤器(DPF)，该过滤器可以通过集成的电加热元件可靠地再生。还将开发一种制造工艺，确保大批量过滤器的经济可制造性。在设计可靠的微粒过滤器和捕集器系统方面，最大的挑战是实现足够的再生，或实现在过滤衬底柴油发动机运行中积累的微粒的氧化(燃烧)。第二阶段的目标将包括设计一种积极再生的过滤器结构，优化用于DPF基板的EC材料，开发适合规模化批量生产的制造工艺，构建DPF基板原型，进行测试，并最终将EC集成的DPF集成到可用于现场测试的功能DPF系统中。第二阶段项目的预期结果是一种积极再生的集成EC的DPF原型基板，适用于美国环保局自愿翻新计划的现场测试。欧盟一体化的DPF将履行定于2007年生效的新排放控制措施。目前迫切需要一种紧凑、易于维护、耐用和有效的柴油微粒过滤器，用于新的和现有的柴油动力车辆。欧共体整合的DPF可能每年减少950万吨柴油颗粒物排放，防止数千人因呼吸系统疾病、癌症和心脏病而过早死亡。。
