SBIR Phase I: Magnetically Actuated Valve System

这个SBIR第一阶段项目将建模，开发，设计和建立一个电磁执行器使用LaunchPoint？的专利非线性磁性弹簧设计。 致动器将用于操作内燃机中的阀。 现代内燃机使用气门正时来优化燃料/空气/排气和混合以实现完全燃烧。 全可变气门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废气排放，并改善发动机的扭矩特性。 用于发动机应用的电磁阀已经在有限数量的内燃机中开发、测试和使用。 在这方面，拟议的技术并不是什么新技术。 但是方法是不同的，技术是不同的，因为它可以提供阀门的受控打开和关闭。所提出的项目的更广泛/商业影响将是可变气门正时将潜在地导致传统火花点火和压缩点火发动机的燃料经济性的提高和排放的减少。 该致动器可以消除许多与凸轮轴驱动相关的发动机部件，从而降低成本。 这项技术可以成为新一代发动机的技术，从而有助于更清洁的环境。

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.
