SBIR Phase I: Magnetically Actuated Valve System

这个SBIR一期项目将使用LaunchPoint？S专利的非线性磁弹簧设计来建模、开发、设计和制造电磁执行器。该执行器将用于操作内燃机中的阀门。现代内燃机使用配气正时来优化燃料/空气/排气和混合，以实现完全燃烧。全可变配气正时系统的可用性具有改善发动机性能的潜力。它将提供气门正时灵活性，这将有助于减少发动机排气排放，并改善发动机的扭矩特性。用于发动机应用的电磁阀已经被开发、测试，并在有限数量的内燃机上使用。在这方面，拟议的技术并不新鲜。但方法不同，技术也不同，因为它可以控制气门的打开和关闭。拟议项目的更广泛/商业影响将是，可变气门正时可能会改善传统的火花点火和压燃式发动机的燃油经济性和减少排放。该执行器可以省去与凸轮轴传动相关的许多发动机部件，从而降低成本。这项技术可以成为新一代发动机的使能技术，这样做可以为更清洁的环境做出贡献。

This SBIR Phase I project will model, develop, design, and build an electromagnetic actuator using LaunchPoint?s patented nonlinear magnetic spring design. The actuator will be used to operate valves in internal combustion engines. Modern internal combustion engines use valve timing to optimize fuel/air/exhaust and mixing for complete combustion. The availability of a full variable valve timing system has the potential to improve engine performance. It will provide valve timing flexibility which will help in reducing engine-out exhaust emissions and improve torque characteristics of the engine. Electromagnetic valves for engine applications have been developed, tested, and used in a limited number of internal combustion engines. In that respect, the proposed technology is not new. But the approach is different and the technology is different in that it can provide controlled opening and closing of the valve.The broader/commercial impact of the proposed project will be that variable valve timing will potentially result in improved fuel economy and reduced emissions for conventional spark ignition and compression ignition engines. The actuator could eliminate many engine components related to camshaft drive and result in reduced costs. This technology could become an enabling technology for new generations of engines and in so doing could contribute to a cleaner environment.
