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.

二甲醚（DME）在内燃机（ICE）中的使用具有优于汽油和柴油燃料的显著优点，潜在地产生非常低的NOx排放和零颗粒物（PM）。 一种用途是通过低温燃烧（LTC）策略，其重点在于（i）开发DME燃烧的预测能力和（ii）开发高压（1500巴）DME燃料喷射系统。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沿着强大的协同理论和计算工作。 其结果将是DME高压喷雾燃烧的综合表征，高度稀释DME自燃的确定（即，发动机爆震）现象作为热化学和化学动力学参数的函数，开发用于排放和燃烧效率的计算流体动力学（CFD）预测工具，以及优化高压DME燃料系统。 在密歇根理工大学、阿贡国家实验室、替代燃料技术和纳威司达的这一联合努力中，将利用各个合作伙伴的实验设施和专业知识。 这项合作不仅将有助于开发以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。
