This Small Business Innovation Research project is concerned with the development of molecular tagging velocimetry (MTV) and its application to in-cylinder engine flows. The proposed research is partly concerned with expanding an existing MTV system to enable measurements of three velocity components (instead of two components) in a planar region within a cylinder. Further, extension of MTV from nitrogen flows to airflows is proposed. Presence of oxygen in air reduces the fluorescent lifetime and poses challenges for MTV measurements. Novel solutions to this problem are proposed. If successful, the proposed technology would enable more efficient and environmentally friendly IC engines and other combustion devices. This would help save fossil fuel energy and minimize air-borne pollutants. Additionally, research applications of the proposed MTV system would help improve modeling of engine flows and transport phenomena. The new computational tools would have wide applications in simulation of reacting flows throughout the process industry.

这个小企业创新研究项目关注的是分子标记测速技术（MTV）的发展及其在缸内发动机流动中的应用。拟议中的研究部分涉及扩展现有的MTV系统，使测量的三个速度分量（而不是两个组件）在一个平面区域内的圆柱。此外，MTV从氮气流的空气流的扩展。空气中氧气的存在降低了荧光寿命，并对MTV测量提出了挑战。针对这一问题提出了新的解决方案。如果成功，所提出的技术将使更高效和环保的内燃机和其他燃烧设备成为可能。这将有助于节省化石燃料能源，并最大限度地减少空气污染物。此外，建议MTV系统的研究应用将有助于改善发动机流动和运输现象的建模。新的计算工具将在整个过程工业的反应流模拟中有广泛的应用。
