SBIR Phase II: Development of an Electrically Regenerated Diesel Particulate Filter

这个小型企业创新研究（SBIR）第二阶段项目提出开发一种有效的柴油颗粒过滤器（DPF），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，以确保大批量过滤器的经济可制造性。 设计可靠的颗粒过滤器和捕集器系统的最大挑战是实现充分的再生，或氧化（燃烧）在过滤器基材柴油发动机运行中积累的颗粒。 第二阶段的目标将包括设计一个主动再生的过滤器结构，优化用于DPF基底的EC材料，开发适合大规模生产的制造工艺，构建原型DPF基底，测试，并最终将集成EC的DPF集成到一个功能性DPF系统中，准备进行现场测试。 第二阶段项目的预期结果是一个积极再生的EC集成DPF原型基板适合在美国环保署的自愿改造计划的现场测试。集成了EC的DPF将实现计划于2007年生效的新排放控制。 目前迫切需要一种用于新的和现有的柴油动力车辆的紧凑、易于维护、耐用且有效的柴油颗粒过滤器。 集成了电子控制器的DPF每年可以减少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。 .

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. .
