SBIR Phase I: Low Emissions Diesel Engines

这个小型企业创新研究第一阶段项目将建立一个新的柴油发动机概念与催化剂技术相结合。 这将大大减少柴油发动机的排放，同时保持提高的燃油效率。 在本计划中，我们将证明火花发动机（低排放）和柴油发动机（提高燃油效率）的最佳特性可以结合起来，生产出一种高燃油效率、低排放的柴油发动机，符合下一代汽车计划（PNGV）伙伴关系的80 mpg目标。 该计划的关键是在柴油发动机中使用适度水平的富氧空气（22-25%的氧气），并结合其他后处理程序。 在第一阶段，我们将展示富氧空气（OEA）所需的增强效果，并根据我们的后处理模型模拟整体系统性能。 这些结果应证明发动机满足PNGV里程和乘用汽车（混合动力车）排放目标和/或满足2002年柴油发动机排放目标的能力。 在第二阶段，我们将把OEA和后处理系统集成到整个发动机包中，进行全尺寸演示。

This Small Business Innovative Research Phase I project will establish a novel diesel engine concept in combination with catalyst technology. This will dramatically reduce diesel engine emissions while maintaining the enhanced fuel efficiency. In this program we will demonstrate that the best features of spark engines (low emissions) and diesel engines (enhanced fuel efficiency) can be combined to produce a high fuel efficiency, low emissions diesel engine consistent with the 80 mpg goals of the Partnership For Next Generation Vehicle Program (PNGV). The key to this program is the use of modest levels of oxygen enriched air (22-25% oxygen) to a diesel engine in combination with other after treatment procedures. In Phase I we will demonstrate the needed enhancements from oxygen enriched air (OEA) and simulate overall system performance based on our after treatment model. These results should demonstrate the engines ability to meet the PNGV mileage and emissions objective for passenger cars (hybrid vehicle) and/or meet the 2002 diesel engine emissions goal. In Phase II we will integrate both OEA and after treatment systems into overall engine package for full scale demonstration.
