Electromagnetic Fully Flexible Valve Actuator 2006-01-0044

An electromagnetic fully flexible valve actuator (FFVA) for internal combustion engines is described which offers the potential for significant improvements in fuel economy, emissions, and performance, especially at low end torque, in internal combustion engines. The FFVA offers variable lift and timing combined with controllable seating velocity. It operates on a design principle distinct from existing actuators: the electromagnetic actuator exerts appreciable bidirectional force throughout the device stroke mitigating the need for mechanical spring-derived resonance. The FFVA is a direct drive device with a unique magnetic structure that combines high bandwidth and strong forces to meet the engine performance requirements.
This paper presents the innovative electromagnetic design, simulation, and bench testing of the actuator on a single cylinder engine.
