*** 9761177 Shdarshan This Small Business Innovation Research Phase I project will attempt to model, design and fabricate Carbon-Carbon composite engine valves. Carbon-Carbon (C-C)composites are materials which are lightweight and exhibit high strengths at elevated temperatures. The density of C-C (1.7g/cc) versus 7.7g/cc for stainless steel and its inherent lubricity are attractive features that render this material as a candidate for engine valves. A significant proportion of engine efficiency is lost in the combustion chamber. If all parts can be redesigned with lightweight materials, the energy efficiency can be improved and the release of pollutants from combustion products decreased. Extensive testing of the valves and redesign, if necessary, of the shapes are planned for the Phase II effort. This process involves extensive dynamometer studies along with long lead times for testing. Potential applications for C-C materials are in all components of the combustion chamber that include pistons, valves, valve guides, rocker arms and connecting rods. ***

这个小企业创新研究第一阶段项目将尝试建模、设计和制造碳-碳复合材料发动机气门。碳-碳（C-C）复合材料重量轻，在高温下表现出高强度。C-C的密度（1.7g/cc）与不锈钢的密度（7.7g/cc）及其固有的润滑性是使这种材料成为发动机气门候选材料的诱人特性。发动机效率的很大一部分是在燃烧室损失的。如果所有部件都可以用轻质材料重新设计，则可以提高能源效率，并减少燃烧产物中污染物的释放。第二阶段计划对阀门进行广泛的测试，并在必要时重新设计阀门的形状。这个过程涉及广泛的测功机研究以及较长的测试前置时间。C-C材料的潜在应用范围包括燃烧室的所有部件，包括活塞、气门、气门导轨、摇臂和连杆。＊＊＊
