In the apparatus for controlling a coasting air recirculation valve of the turbocharger of an internal combustion engine, the coasting air recirculation valve is arranged in the coasting air recirculation line bypassing a compressor in the intake duct, and the coasting air recirculation valve is controllable by way of the intake duct pressure on the downstream side of the throttle valve. In order to ensure defined opening and closing of the coasting air recirculation valve, an additional control pressure, with which the coasting air recirculation valve can be opened independently of the intake duct pressure, can be delivered to the coasting air recirculation valve.
An apparatus for controlling a coasting air recirculation valve of a turbocharger of an internal combustion engine, the coasting air recirculation valve being arranged in a coasting air recirculation line of the internal combustion engine, the coasting air recirculation line bypassing a compressor which is disposed in an intake duct, the apparatus comprising:
