项目摘要

Abstract#1159279Schwank, JohannesIt is well-known that catalytic emission control strategies for vehicles exact a toll on vehicle fuel economy. With the requirements to drastically increase the corporate average fuel economy, such fuel economy penalties will no longer be acceptable, and a new approach to gasoline vehicle emission control catalysis is needed. This GOALI proposal brings together a team of researchers from academia and industry in a quest to arrive at a detailed understanding how new fuel economy-enabling powertrain technologies such as gasoline-electric hybrids, engine start-stop features, down-sized turbocharged engines with direct injection, and use of reformulated gasoline or E-85 impacts the function and deactivation modes of existing three-way Pd catalyst materials. The proposal will also address methods for curtailing and, ideally even reversing catalyst deactivation on the vehicle during actual operation. Traditionally, catalyst deactivation has only been looked at from a post mortem perspective. There is a dearth of investigations of the time-dependent changes occurring in emission control catalysts when exposed to emissions from engines operating under various exhaust gas environments and temperature regimes. Professor Johannes Schwank, Adjunct Professor Galen Fisher, and Dr. Xiaoyin Chen at the University of Michigan will closely collaborate with Dr. Robert McCabe at Ford Motor Company to utilize sophisticated probe reaction analysis and characterization techniques to elucidate the complete evolution of the Pd catalyst from its initial to final states, with the goal of identifying opportunities to modify the engine operation in ways that either mitigate catalyst deactivation or reverse deactivation processes. The hypothesis is that different aging protocols lead to different outcomes in catalyst structure and performance. This hypothesis will be tested by a comprehensive catalyst characterization effort at different stages of aging. In terms of broader impact, this research will aid the design of future automotive emission control technologies, while also improving the performance and durability of existing automotive exhaust catalyst technologies. The results will assist in developing methods to track the aging process on the vehicle and either avoid severe aging modes or actively intervene at various points to preserve or regenerate the catalyst. Given the close proximity of the two institutions, the project will provide opportunities for Ford researchers to participate in experiments at UM, and UM faculty and students to experience working in an industrial research laboratory at Ford, thereby giving the students an educational experience that goes beyond typical academic settings.
摘要#1159279SCHWANK,JOHANNESIT众所周知,车辆的催化排放控制策略恰好对车辆燃油经济性造成了损失。 由于需要大幅度提高公司平均燃油经济性的要求,因此这种燃油经济性惩罚将不再是可以接受的,并且需要采取新的汽车排放控制催化方法。 This GOALI proposal brings together a team of researchers from academia and industry in a quest to arrive at a detailed understanding how new fuel economy-enabling powertrain technologies such as gasoline-electric hybrids, engine start-stop features, down-sized turbocharged engines with direct injection, and use of reformulated gasoline or E-85 impacts the function and deactivation modes of existing three-way Pd catalyst materials.该提案还将解决限制的方法,理想情况下,甚至在实际操作过程中扭转了车辆上的催化剂。传统上,催化剂停用仅是从mortem后的角度看待的。当暴露于在各种排气环境和温度方面运行的发动机的排放时,对发射控制催化剂中发生的时间依赖性变化的研究不足。密歇根大学的兼职教授,加伦·费舍尔(Galen Fisher)教授约翰内斯·施万克(Johannes Schwank)教授和小杨陈(Chen Chen)将与福特汽车公司的罗伯特·麦卡比(Robert McCabe)博士密切合作,利用探测反应分析和表征技术,以阐明PD催化剂的最初效果,以使其最初的型号的努力,从停用或反向停用过程。假设是不同的老化方案导致催化剂结构和性能的不同结果。该假设将通过在衰老的不同阶段进行全面的催化剂表征进行检验。在更广泛的影响方面,这项研究将有助于设计未来的汽车排放控制技术,同时还提高了现有的汽车排气催化剂技术的性能和耐用性。结果将有助于开发跟踪车辆衰老过程的方法,避免严重的老化模式,或在各个点进行积极干预以保存或再生催化剂。鉴于这两个机构的近距离,该项目将为福特研究人员提供机会参加UM的实验,UM教师和学生在福特的工业研究实验室工作,从而为学生提供了超越典型的学术环境的教育经验。
