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

这项小型企业创新研究（SBIR）二期研究项目将为全柔性电磁汽车发动机气门开发一种新型径向磁场执行器。电磁阀执行器正迅速成为改善排放、燃油消耗和提高发动机性能的技术解决方案。该技术可以显著提高发动机性能，减少对环境的影响。全电子控制的进排气门执行系统完全消除了凸轮轴和其他机械部件，因此(1)可以优化整个发动机转速和负载范围内的气体交换过程，(2)消除了传统凸轮轴剖面对发动机的包装限制。执行器的主要应用是汽车内燃机气门。改变汽车发动机气门的升力和时间（开启和关闭）的能力将创造更强大的发动机，需要更少的燃料，产生更少的排放。仅在节省燃料方面，估计就可以实现15%的节省，相当于每年为美国消费节省约4.75亿桶石油，价值约为210亿美元。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，并提高汽车竞争力。

This Small Business Innovation Research (SBIR) Phase II research project will develop a novel radial magnetic field actuator for fully flexible electromagnetic automotive engine valves. Electromagnetic valve actuators are rapidly emerging as the technical solution for improved emissions, fuel consumption and greater engine performance. Dramatic improvement in engine performance and reduction in environmental impact is possible with this technology. A fully electronically controlled inlet/exhaust valve actuating system eliminates camshafts and other mechanical components completely, thus (1) allowing optimization of the gas-exchange process across the whole engine speed and load range, and (2) eliminating the packaging restrictions placed upon an engine by conventional camshaft profiling. The primary application of the actuator is automotive internal combustion engine valves. The ability to alter the lift and timing (opening and closing) of automotive engine valves will create more powerful engines that require less fuel and create fewer emissions. In fuel savings alone, an estimated 15% savings can be achieved, which equates to saving approximately 475 million barrels of oil per year for US consumption worth approximately $21 billion per year. 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 increase automotive competitiveness.
