A dye laser system will be purchased to support fundamental investigations of Diesel combustion and emission formation processes being conducted in two unique experimental facilities -an optically accessible, DI Diesel engine and a high pressure, chemical flow reactor. An Engine Company, NSF, and the Department of Energy are sponsoring research on the evolution of soot and NO within the combustion chamber of a specially constructed Diesel engine; this research uses laser- based, planar imaging of soot and NO. The objective of the study is to obtain an improved understanding of the processes so that in-cylinder strategies can be developed to simultaneously reduce NOx and particulate emissions. To complement the engine research on Diesel combustion, a high pressure, chemical flow reactor is being used to study the effects of pressure on the chemistry of hydrocarbon auto- ignition related to Diesel cold starting and knock. In addition to the measurement of stable products, important radical species will be determined by fluorescence or adsorption techniques. This research is motivated by the needs of Diesel engine manufacturers who cannot meet the NOx and particulate emissions standards set by the Environmental Protection Agency for 1994 without the use of particulate traps which will adversely affect engine reliability and fuel economy.

将购买一个染料激光系统， 柴油机燃烧和排放物形成的研究 在两个独特的实验过程中进行 设施-一个光学访问，直喷柴油发动机和一个 高压化学流动反应器。 一家发动机公司，NSF， 和能源部正在赞助一项研究， 碳烟和NO的演变在燃烧室内的一个 特别构造的柴油发动机;这项研究使用激光- 基于，平面成像的烟尘和NO。 研究是为了更好地了解这些过程 这样就可以开发缸内策略， 同时减少NOx和微粒排放。 到 补充发动机对柴油机燃烧的研究， 压力，化学流反应器被用来研究 压力对碳氢化合物化学性质的影响 点火与柴油机冷起动和爆震有关。 在 除了测量稳定的产品，重要的是 自由基物质将通过荧光或 吸附技术 本课题的研究是由柴油机的需要而引起的 无法满足NOx和颗粒物排放标准的制造商 环境保护局制定的排放标准 1994年不使用微粒收集器， 不利地影响发动机可靠性和燃料经济性。
