The Small Business Innovation Research (SBIR) Phase 1 project will evaluate the feasibility of utilizing Line Scan X-Ray Tomography to characterize the combustion process inside internal combustion engines. The two innovative parts of the proposed work are a high frequency Line Scan X-Ray tomography system and an advanced statistical deconvolution method. These two innovations will enable the determination of the structure of flames and high-pressure sprays inside internal combustion engines. The innovation enables property estimation inside engines without the need for optical or acoustic windows. The proposed work builds on the company's expertise in developing statistical deconvolution methods for industrial process tomography. There are two primary commercial applications for the proposed Line-Scan X-ray tomography system. The first is the estimation of flame structure within automotive engines. New federal regulations, scheduled to become effective in FY11, mandate much lower pollutant emissions from automotive engines than are currently permitted. The second is the determination of pattern factors inside turbines. Newer turbine engines used for power production run at high temperatures that can significantly degrade thermal barrier coatings if hot spots exist. The proposed system will provide previously unavailable information within automotive and turbine engines, leading to tighter control on pollution and engine performance.

小型企业创新研究（SBIR）第1阶段项目将评估使用线条扫描X射线断层扫描来表征内燃机内部燃烧过程的可行性。 拟议工作的两个创新部分是高频线扫描X射线断层扫描系统和先进的统计反卷积方法。 这两项创新将能够确定内燃机内部火焰和高压喷雾剂的结构。 该创新可以实现发动机内部的属性估计，而无需光学窗口或声学窗口。 拟议的工作是基于公司在开发工业过程层析成像统计反卷积方法方面的专业知识。拟议的线扫X射线断层扫描系统有两个主要的商业应用。 首先是汽车发动机中火焰结构的估计。 原定于2011财年有效的新联邦法规要求汽车发动机的污染物发射要比目前允许的要低得多。 第二个是确定涡轮机内的模式因子。 用于发电的新涡轮发动机在高温下运行，如果存在热点，这些发动机可能会大大降低热屏障涂料。 拟议的系统将在汽车和涡轮发动机中提供以前无法获得的信息，从而更严格控制污染和发动机性能。
