This SBIR Phase I project will develop a water separator media to protect heavy duty engines from the water content in modern ultra low sulfur diesel fuels. The ultra low sulfur diesel fuel typically found in the field has very low interfacial tension allowing water to be present in the form of very fine droplets which pass through conventional water separators and end up in the fuel injection system. This project will quantify and develop a functionalized multiwall carbon nanotube-based water separator to be used with all ultra low sulfur diesel fuels on the market with nearly 100% water removal efficiency. The objective is to enhance the separator performance to cost ratio by working to further increase the separation efficiency and lower the media cost through process scaling and materials development.The broader impact/commercial potential of the project are focused on benefits related to enhanced ultra low sulfur diesel fuel separation, including more consistent fuel delivery to the engine, longer injector/engine life, better combustion of ultra low sulfur diesel fuel, lower maintenance costs, new jobs enabled by the use of high-sulfur fuel reserves, and more efficient combustion of bio-fuels. Reduced water content in the fuel will help to improve performance of the high pressure fuel injection systems, maintain tolerances of the fuel injection system components, and reduce maintenance costs.

该SBIR一期项目将开发一种水分离介质，以保护重型发动机免受现代超低硫柴油燃料中的水含量的影响。超低硫柴油通常具有非常低的界面张力，允许水以非常细的液滴形式存在，通过传统的水分离器并最终进入燃油喷射系统。该项目将量化并开发一种功能化的多壁碳纳米管水分离器，用于市场上所有超低硫柴油，去除率接近100%。目标是通过工艺缩放和材料开发，进一步提高分离效率，降低介质成本，从而提高分离器的性能与成本比。该项目更广泛的影响和商业潜力集中在与超低硫柴油燃料分离相关的好处上，包括更一致的燃料输送到发动机，更长的喷油器/发动机寿命，更好的超低硫柴油燃烧，更低的维护成本，使用高硫燃料储备带来的新工作，以及更有效的生物燃料燃烧。降低燃油中的水分含量将有助于提高高压燃油喷射系统的性能，保持燃油喷射系统部件的公差，并降低维护成本。
