This project will provide instrumentation to support research on the vaporization of thin films composed of non-ideal mixtures of fuels typically utilized in internal combustion engines. A research-grade Fourier transform infrared spectrometer, a high speed digital camera, a stabilized helium-neon laser, and a pressure chamber will be used to measure the composition and mass of vaporizing multicomponent fuel films as a function of time. The experimental research will provide key kinetic information about fuel film combustion, which is necessary for successful modeling of combustion processes. Furthermore, as fuel films form in internal combustion engines, they affect fuel-air mixing: pollutant emissions can be drastically altered. The research will lead to a better understanding of how fuel films contribute to pollutant emissions from engines by: 1) improving the understanding of the roles of thermal and mass transport processes within the films, and 2) providing a thorough characterization of the changing film composition during vaporization. The broader educational aspects of the work will include the education of undergraduate and graduate students in design and analysis in a multidisciplinary research program. This will further strengthen a strong tradition of undergraduate research at Trinity University and will foster closer relations between engineering sciences and chemistry.

该项目将提供仪器，以支持对由内燃机中通常使用的非理想燃料混合物组成的薄膜蒸发的研究。 研究级傅里叶变换红外光谱仪，高速数码相机，稳定的氦氖激光器，和压力室将被用来测量作为时间的函数的汽化多组分燃料膜的成分和质量。 实验研究将提供关键的动力学信息的燃料膜燃烧，这是必要的成功的燃烧过程的模型。 此外，由于燃料膜在内燃机中形成，它们会影响燃料-空气混合：污染物排放可能会急剧改变。 该研究将通过以下方式更好地了解燃料膜如何影响发动机的污染物排放：1）提高对膜内热传递和质量传递过程作用的理解，以及2）提供汽化过程中膜成分变化的全面表征。 更广泛的教育方面的工作将包括本科生和研究生的教育，在设计和分析的多学科研究计划。 这将进一步加强Trinity大学本科生研究的强大传统，并将促进工程科学和化学之间更密切的关系。
