Abstract#1258720Lee, Seong-YoungUse of dimethyl ether (DME) in the internal combustion engine (ICE) has significant advantages over gasoline and diesel fuels, potentially yielding very low NOx emissions and zero particulate matter (PM). One usage is through low-temperature combustion (LTC) strategies, the focus of which aims to (i) develop a predictive capability for DME combustion and (ii) develop a high-pressure (1500 bar) DME fuel injection system. Fundamental, phenomenological, and quantitative studies will be carried out over a wide range of pressures and temperatures, utilizing state-of-the-art experimental facilities along with strong synergistic theoretical and computational efforts. The outcome will be a comprehensive characterization of DME high-pressure spray combustion, a determination of highly dilute DME autoignition (i.e., engine knock) phenomenon as a function of thermo-chemical and chemical kinetic parameters, development of computational fluid dynamics (CFD) predictive tools for emissions and combustion efficiency, and optimization of a high pressure DME fuel system. In this joint effort among Michigan Technological University, Argonne National Laboratory, Alternative Fuel Technology, and Navistar, the experimental facilities and expertise of individual partners will be leveraged. Not only will this collaboration contribute to the development of an advanced ICE fueled with DME, significant educational impacts will also result. An integrated educational program provides research opportunities for students through close collaboration with Argonne National Laboratory and the industrial partners.

摘要#1258720Lee, Seong-Young 在内燃机 (ICE) 中使用二甲醚 (DME) 比汽油和柴油燃料具有显着优势，可能产生极低的氮氧化物排放和零颗粒物 (PM)。 一种用途是通过低温燃烧 (LTC) 策略，其重点旨在 (i) 开发 DME 燃烧的预测能力，以及 (ii) 开发高压（1500 bar）DME 燃油喷射系统。基础、现象学和定量研究将在广泛的压力和温度范围内进行，利用最先进的实验设施以及强大的协同理论和计算工作。 结果将是 DME 高压喷雾燃烧的综合表征、确定高度稀释的 DME 自燃（即发动机爆震）现象作为热化学和化学动力学参数的函数、计算流体动力学 (CFD) 预测的发展排放和燃烧效率工具，以及高压 DME 燃油系统的优化。 在密歇根理工大学、阿贡国家实验室、替代燃料技术和 Navistar 的共同努力中，各个合作伙伴的实验设施和专业知识将得到利用。 此次合作不仅有助于开发以 DME 为燃料的先进 ICE，还将产生重大的教育影响。综合教育计划通过与阿贡国家实验室和工业合作伙伴的密切合作为学生提供研究机会。
