Abstract
A turbocharger includes a housing, a turbine wheel, a bypass channel formed in the housing, a wastegate assembly having a valve and configured to selectively allow a flow of exhaust gas to bypass the turbine wheel via the bypass channel, and a wastegate outer housing having an aperture fluidly coupled to the bypass channel, and an outer valve seating surface, the valve configured to selectively seat against the outer valve seating surface over the aperture. A shroud extends outwardly from the wastegate outer housing and is configured to direct the bypass exhaust gas flow toward a catalytic converter.
