Abstract
A variable geometry turbocharging system for use in an internal combustion engine utilizes a voice coil assembly. The voice coil assembly includes a field and an armature. The voice coil assembly is actuatable to move the armature relative to the field, and is connected to the turbocharger such that movement of the armature relative to the field changes the geometry of the turbocharger.
