This PFI: AIR Technology Translation project focuses on translating the synergistic combination of low heat rejection (LHR) and low temperature combustion (LTC) to fill the technological gap between existing commercially available internal combustion engines and the clean high-efficiency advanced combustion engine. The translated LHR/LTC technology has the following unique feature: low heat rejection from a low temperature combustion engine that results in more favorable thermodynamics compared to either conventional or ordinary low temperature combustion engines. This provides exemplary efficiency, engine-out exhaust emissions of nitrogen oxides and fixed carbon, and suitable exhaust temperatures for favorable operation of exhaust emission control systems when compared to the leading competing internal combustion engine. The project accomplishes its objectives by performing a proof-of-concept that experimentally and computationally realizes LHR concepts with LTC in a compression ignition engine resulting in a prototype LHR/LTC combustion mode operating in a light-duty automotive diesel engine. The partnership engages General Motors, which engineers and manufacturers the prototype-intended light-duty automotive engine. GM provides guidance in the global automotive market space such as operating constraints, cost limitations, and technology integration with a marketable product in order to translate LHR/LTC combustion along a path that may result in a competitive commercial reality. The potential economic impact is expected to be nearly $40million in the next 10 years (based on new diesel vehicle registrations in the United States demonstrating on average $256/year in fuel cost savings at $4.00/gallon fuel cost), which will contribute to the U.S. competitiveness in this automotive market space. The societal impact, long term, will be improved vehicle fuel economy with reduced emission of criteria pollutants (e.g., nitrogen oxides), thereby reducing vehicle carbon footprint. Additionally, this effort will augment the investigators? efforts to increase female and underrepresented students in STEM disciplines and improve undergraduate student course instruction in thermodynamics by leveraging resources used for summer STEM camps and course redesign activities. Finally, scholarly articles and conference presentations will be disseminated to ensure scientific and technological pathway discoveries are made known.

该PFI：AIR技术翻译项目的重点是翻译低热阻（LHR）和低温燃烧（LTC）的协同组合，以填补现有商用内燃机和清洁高效先进内燃机之间的技术差距。转化后的 LHR/LTC 技术具有以下独特功能：低温内燃机的排热量低，与传统或普通低温内燃机相比，可产生更有利的热力学性能。与领先的竞争内燃发动机相比，这提供了示范性的效率、氮氧化物和固定碳的发动机排出废气排放以及适合废气排放控制系统有利操作的废气温度。该项目通过进行概念验证来实现其目标，通过实验和计算在压燃式发动机中实现 LHR 概念和 LTC，从而产生在轻型汽车柴油发动机中运行的原型 LHR/LTC 燃烧模式。此次合作涉及通用汽车公司，该公司负责设计和制造原型轻型汽车发动机。通用汽车在全球汽车市场领域提供指导，例如运营限制、成本限制以及与适销产品的技术集成，以便将 LHR/LTC 燃烧转化为可能产生竞争性商业现实的路径。预计未来 10 年潜在的经济影响将达到近 4000 万美元（根据美国新登记的柴油车，按 4.00 美元/加仑的燃油成本计算，每年平均可节省 256 美元的燃油成本），这将有助于美国在这个汽车市场领域的竞争力。从长远来看，社会影响将是提高车辆燃油经济性，减少标准污染物（例如氮氧化物）的排放，从而减少车辆碳足迹。此外，这项工作将增强调查人员的能力？通过利用夏季 STEM 夏令营和课程重新设计活动的资源，努力增加 STEM 学科中女性和代表性不足的学生，并改善本科生热力学课程教学。最后，将传播学术文章和会议演讲，以确保科学和技术途径的发现为人所知。
