Power System Including a Variable Geometry Turbocompound Turbine

摘要

Disclosed is a power system having a turbocharger, a VG turbocompound turbine, and a controller. The turbocharger has a turbine coupled to a compressor, and the VG turbocompound turbine positioned downstream of the turbine relative to a direction of a flow of an exhaust gas flowing through the turbine and the VG turbocompound turbine. The controller sends a signal to adjust a geometry of the VG turbocompound turbine so as to adjust a boost level being provided by the turbocharger.
