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

该小型企业创新（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阀门的新型径向磁场致动器。该技术可以显著提高发动机性能并减少对环境的影响。即将在国际上采用的42V汽车电源系统增强了这种方法。完全电子控制的进气门/排气门致动系统完全消除了凸轮轴，从而（1）消除了传统凸轮轴成型对发动机的封装限制，以及（2）允许在整个发动机速度和负载范围内优化气体交换过程。该概念的商业应用包括：汽车发动机气门致动器、通用线性致动器、汽车主动悬架和无人机飞行致动器。机电气门技术的一个主要社会效益将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，并降低车辆运营成本。

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.
