GOALI: DFB Laser Sensors for Fast, Quantitative Interrogation of Harsh Combustion SystemsM.S. Wooldridge, University of Michigan and S.T. Wooldridge, Ford Motor CompanyProject AbstractAdvanced combustion strategies have considerable potential to dramatically improve combustion efficiencies while simultaneously reducing pollutant emissions. Realization of this potential requires parallel advances in interrogation and sensing methods to provide feedback on the projected conditions within the combustion chamber and to provide metrics for assessing successful technologies. This project focuses on development and application of a laser-based sensing method for interrogation of combustion systems where the high temperatures, pressures and rapid transients present considerable challenges for conventional experimental approaches. Specifically, this work will use distributed feedback diode lasers as emission sources for absorption spectroscopy to measure species important in internal combustion (IC) engines. Novel frequency modulation and wavelength multiplexing will be used to improve temporal resolution and detection limits. The diagnostic will be developed and applied to a optical engine facility, where a partnership with Ford Motor Company will ensure rapid dissemination of the methods to industrial research and development facilities. Difficulties associated with engine measurements will be addressed in the course of this work using the characteristics of the resonant and off-resonant absorption features. Measurements proposed in this work include absolute quantitative in-cylinder species concentrations with good temporal resolution continuously acquired throughout an engine cycle, without cycle-to-cycle averaging. The collection of data such as these is a vital next step in IC engine research and development. Direct outcomes of the proposed research include important advancements in solid-state lasers and absorption spectroscopy along with a new valuable tool for combustion studies that can be applied to a broad range of systems. Increased understanding of the physical and chemical mechanisms important in advanced IC engine combustion systems will significantly aid in the development of advanced engine technologies. The broader impacts therefore include the potential to design and produce IC engines with better fuel economy while simultaneously decreasing pollutant emissions. This project is co-funded by the Grant Opportunities for Academic Liaison with Industry (GOALI) program and the Combustion and Plasma Systems program.

GOALI：DFB激光传感器，用于快速、定量检测恶劣的燃烧系统Wooldridge，密歇根大学和S.T. Wooldridge，福特汽车公司项目摘要先进的燃烧策略有相当大的潜力，大大提高燃烧效率，同时减少污染物的排放。 实现这一潜力需要在询问和传感方法方面取得平行进展，以提供有关燃烧室内预计条件的反馈，并提供评估成功技术的指标。 该项目的重点是开发和应用基于激光的传感方法，用于燃烧系统的询问，其中高温，高压和快速瞬变对传统的实验方法提出了相当大的挑战。 具体而言，这项工作将使用分布反馈二极管激光器作为吸收光谱的发射源，以测量内燃机（IC）发动机中重要的物质。 新的频率调制和波长多路复用将用于提高时间分辨率和检测限。 该诊断将被开发并应用于光学发动机设施，在那里与福特汽车公司的伙伴关系将确保该方法迅速传播到工业研究和开发设施。 与发动机测量相关的困难将在这项工作的过程中使用的谐振和非谐振吸收功能的特性来解决。在这项工作中提出的测量包括绝对定量缸内物种浓度与良好的时间分辨率连续获得整个发动机循环，没有周期到周期的平均。 这些数据的收集是内燃机研究和开发的重要下一步。 拟议研究的直接成果包括固态激光器和吸收光谱学的重要进展，沿着一种新的有价值的燃烧研究工具，可应用于广泛的系统。 提高对先进内燃机燃烧系统中重要的物理和化学机理的理解将大大有助于先进发动机技术的发展。 因此，更广泛的影响包括设计和生产具有更好燃油经济性的内燃机，同时减少污染物排放的潜力。 该项目由学术联络与工业（GOALI）计划和燃烧和等离子体系统计划的赠款机会共同资助。
