Abstract: An exhaust gas recirculation (EGR) system that utilizes an insulated separation wall that separates the hot, humid EGR gas duct from the cool, dry inlet air duct in the upstream proximity of the compressor inlet of the associated turbocharger compressor. This insulated separation wall inhibits the condensation of water droplets and the formation of ice particles near the mixing point of the EGR gases and inlet air in the upstream proximity of the compressor inlet, such that the turbocharger compressor wheel, blades, and other components are not subsequently damaged by the condensed water droplets or formed ice particles. The added insulation in this cold sink area essentially thermally isolates the hot, humid EGR gas flow from the cool, dry inlet air flow until the actual mixing point of the flows.

Abstract: An actuator includes a first enclosure, a dielectric fluid in the first enclosure, and a second enclosure in fluid communication with the first enclosure. An elastic membrane defines at least a portion of the second enclosure. A first electrical conductor is positioned along a first side of the first enclosure. A second electrical conductor is positioned along a second side of the first enclosure opposite the first side. The second conductor is spaced apart from the first conductor. The conductors are connected to a power source. Application of electrical energy to the first and second conductors produces an attractive force between the conductors. Motion of the conductors toward each other pressurizes the dielectric fluid so as to force the dielectric fluid to flow from the first enclosure into the second enclosure. The flow of the dielectric fluid exerts a force on the elastic membrane which expands the elastic membrane.
