Summary:

Modern air intake systems require active air management to solve the contrary development goals of a high performance engine and to comply with sound emission regulations. Therefore at various locations in the air ducts, flaps and other switching devices tune the air management system according to the engine performance. The conventional vacuum actuators are more and more replaced by electrical systems due to assembly and packaging advantages and the lack of vacuum in critical engine situations.The development goal was to design a highly integrated system where the actuator is located inside the switching device in the first case a butterfly flap. The design consists of a fixed stator shaft with integrated coils, connectors and injection molded fasteners and bearings. The system is designed for extreme packaging requirements, because outside no additional device has to be assembled. The system is promising significantly lower costs than conventional systems.First applications investigated will be resonance flaps in intake manifolds, water protection flaps before the air flow meter and variable acoustic resonators
