Abstract:
A turbocharger system for an engine of a vehicle includes a variable geometry turbine configured to receive exhaust gas from the engine. The variable geometry turbine includes adjustable vanes and a vane actuator to adjust the adjustable vanes between at least an open position and a closed position. The turbocharger further includes an intake duct configured to receive intake air; a first compressor rotationally coupled to the variable geometry turbine and fluidly coupled to the intake duct to compress at least a first portion of the intake air; an electric compressor fluidly coupled to the intake duct to selectively compress at least a second portion of the intake air; and a manifold conduit fluidly coupled to the first compressor and the electric compressor and configured to receive and direct the first and second portions of the intake air to a manifold of the engine.
