SBIR Phase II: Magnetically Actuated Valve System

这个小企业创新研究（SBIR）第二阶段项目致力于开发和测试电磁阀系统（MVS），使电子控制可变正时的无凸轮内燃机的实施。MVS是一种先进的执行机构，用于内燃机的进气和排气提升阀，用于控制新鲜进气和排气的流量。LaunchPoint Technologies，Inc.将设计和建造MVS执行器，并在实验内燃机上演示其操作。MVS技术的优势源于磁弹簧执行器的特性，它在阀门打开和关闭过程中提供了对阀门位置和速度的有效控制。LaunchPoint？的成本效益和强大的技术将使备受期待的电子控制可变气门正时的大规模生产发动机的实施。更广泛的影响，这项研究是一个显着的改善相结合的燃油效率，减少排放，并改善传统的火花点火和压缩点火发动机的动力特性。当可靠的电子控制系统交付使用时，这项技术的经济和社会影响将是广泛的。MVSAactuator可以潜在地用于汽车、卡车、推土机和固定发电机中使用的数百万内燃机。它将实现新兴的先进燃烧技术，如均质充量压缩点火和压缩空气混合动力。MVS执行器的广泛采用将导致石油使用量的大幅减少，对环境的不利影响，如空气污染和温室气体的产生，并提高能源独立性。

This Small Business Innovation Research (SBIR) Phase II project is dedicated todevelopment and testing of Magnetic Valve System (MVS) enabling implementation ofelectronically controlled variable timing on camless internal combustion engines. MVS is anadvanced actuator for intake and exhaust poppet valves utilized in internal combustion enginesfor control of flows of fresh charge and exhaust gases. LaunchPoint Technologies, Inc. willdesign and build the MVS actuator and demonstrate its operation on an experimental internalcombustion engine. The advantages of MVS technology originate from the nature of the magneticspring actuator that provides efficient control of the valve position and speed during valveopening and closing events. LaunchPoint?s cost-effective and robust technology will enableimplementation of highly anticipated electronically controlled variable valve timing on a massproduction engine.The broader impacts of this research are a combination of significant improvementsin fuel efficiency, reduction of emissions, and improved power characteristics of conventionalspark ignition and compression ignition engines. When a reliable, electronically controlledsystem is delivered, the economic and social impact of this technology will be broad. The MVSactuator can potentially be used in millions of internal combustion engines employed inautomobiles, trucks, bulldozers, and stationary generators. It will enable implementation ofemerging advanced combustion technologies such as Homogeneous Charge CompressionIgnition and Compressed Air Hybrid. Widespread adoption of MVS actuators would result insubstantial decrease of petroleum usage, adverse effects on the environment such as air pollutionand greenhouse gas production, and improve energy independence.
