Abstract
A variable turbine geometry (VTG) turbocharger () includes a VTG assembly () for controlling guide vanes () in combination with a wastegate assembly () having a wastegate valve () configured to control exhaust gas flow through a wastegate port () in the turbine housing () thereby selectively bypassing the turbine wheel (). The guide vanes () are actuated continuously, while the wastegate valve () only starts to open at a predetermined configuration of the VTG assembly () in which the guide vanesare open to a set amount. For some exhaust gas flow rates, the guide vanes () and the wastegate valve () are fully open at the same time. A common actuator () controls both the guide vanes () and the wastegate valve () of the wastegate assembly ().
