Abstract

A method is introduced for controlling a turbocharger that generates a charging pressure in an intake plenum. The charging pressure is controlled on the turbine side, and the turbocharger has a circulating-air valve that temporarily opens a flow-cross section between the intake plenum and a suction side of the turbocharger when an air mass flow flowing out of the intake plenum is reduced. Under certain operating conditions, in addition to the turbine-side control by adjusting a turbine flow cross-section, the charging pressure is reduced by opening the circulating-air valve. Furthermore, a control device is introduced that implements the process.
