SBIR Phase I: Titanium Automotive Powertrain Componenets For Increased Fuel Efficiency And Reduced Emissions

这个小型企业创新研究(SBIR)第一阶段项目...将开发轻量化的钛发动机部件，以提高燃油效率。使用先进的钛基金属基复合材料可以显著提高汽车的燃油效率，减少温室气体排放。钛金属基复合材料还可以降低发动机振动。车辆重量的减轻是因为用更轻的钛取代了钢，也因为往复重量所需的振动管理系统大大减少了。钛在汽车发动机零部件中应用的主要障碍是耐磨性差和成本高。所提出的高能效制造工艺能够以比传统方法更低的成本生产这些钛部件。Dynamet？S金属基复合材料保留了钛的优点(重量轻、高比强度和耐腐蚀性)，同时克服了使用的主要障碍。这项研究的更广泛/商业影响是改善发动机的燃油效率。拟议的减轻发动机重量的技术有可能提高燃油效率，减少商用乘用车和中型和重型卡车发动机的温室气体排放。S提出的使用新材料和制造技术可以为国家应对气候变化和减少国家对外国石油的依赖做出重大贡献。该技术还可以应用于非公路发动机、非发动机汽车应用和军用地面车辆。

This Small Business Innovation Research (SBIR) Phase I project...will develop lightweight titanium engine components for fuel efficiency. The use of advanced titanium-based metal matrix composite materials can significantly improve automotive fuel efficiency and reduce greenhouse gas emissions. The titanium metal matrix composites also can reduce engine vibration. Reduction in vehicle weight results from the substitution of lighter weight titanium for steel and also from the significantly reduced vibration management system needed for reciprocating weight. The major barriers to the adoption of titanium for automobile engine components has been its poor wear resistance and high cost. The proposed energy efficient manufacturing process can produce these titanium components at lower cost than conventional methods. Dynamet?s metal matrix composites retain the benefits of titanium (lightweight, high specific strength and corrosion resistance) while overcoming the major barriers to its use.The broader/commercial impacts of this research are improvements to engine fuel efficiency. The proposed technology for reducing engine weight has the potential for increasing fuel efficiency and reducing greenhouse gas emissions from engines in commercial passenger automobiles and in medium and heavy-duty trucks. The use of the proposed novel materials and manufacturing technology can significantly contribute to the nation?s effort to stem climate change and to lessen the nation?s dependence on foreign oil. The technology can also apply to off-highway engines, non-engine automotive applications and to military ground vehicles.
