SBIR Phase I: Novel Radial Magnetic Field Actuator for Fully Flexible Electromechanical Valve

这项小型企业创新（SBIR）第一阶段研究项目将开发一种用于全柔性电磁汽车发动机气门的新型径向磁场执行器。该技术可以显著提高发动机性能，减少对环境的影响。即将在国际上采用的42V汽车电源系统增强了这种方法。全电子控制的进排气气门驱动系统完全消除了凸轮轴，因此(1)消除了传统凸轮轴剖面对发动机的包装限制，(2)允许在整个发动机转速和负载范围内优化气体交换过程。提出的概念的商业应用包括：汽车发动机气门执行器，一般线性执行器，汽车主动悬架和无人机飞行执行器。机电阀技术对社会的一个主要好处是更好的燃油经济性。提高燃油经济性是一个有价值的国家目标：它将减少美国对进口石油的依赖，减少导致全球变暖的碳排放，并降低汽车运营成本。

This Small Business Innovation (SBIR)Phase I research project will develop a novel radial magnetic field actuator for fully flexible electromagnetic automotive engine valves. Dramatic improvement in engine performance and reduction in environmental impact is possible with this technology. The imminent international adoption of a 42V automotive power system enhances the approach. A fully electronically-controlled inlet/exhaust valve actuating system eliminates camshafts completely, thus (1) eliminating the packaging restrictions placed upon an engine by conventional camshaft profiling, and (2) allowing optimization of the gas exchange process across the whole engine speed and load range. Commercial applications of the proposed concept include: automotive engine valve actuators, general linear actuators, automotive active suspension, and unmanned aerial vehicle flight actuators.A major benefit to society of electromechanical valve technology will be better fuel economy. Improving fuel economy is a worthy national goal: it will reduce America's dependence on imported oil, cut the carbon emissions that contribute to global warming, and reduce vehicle operating cost.
