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

这个小型企业创新研究（SBIR）二期项目旨在开发一种有效的柴油微粒过滤器（DPF），该过滤器可以通过集成的电热元件可靠地再生。还将开发一种制造工艺，以确保高容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）积聚在过滤器基片中的颗粒柴油发动机运行。第二阶段的目标将包括设计一个主动再生过滤器结构，优化用于DPF基板的EC材料，开发适合批量生产的制造工艺，构建原型DPF基板，测试，并最终将EC集成DPF集成到一个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积极再生ec集成DPF原型基板，适用于美国环保署的现场测试。自愿改造计划。与欧共体集成的DPF将符合定于2007年生效的新的排放控制规定。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。ec集成的DPF每年可能减少950万吨柴油微粒排放，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. .
