Abstract

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