ABSTRACT:
A device and method for supplying fresh air to a turbocharged piston internal combustion engine are described. According to the invention, a fresh gas line section of an intake manifold has an adjustable flap, and inlet and outlet ports. An adjustment device is coupled to the flap for adjusting the flap. A compressed air port having an opening leading into a chamber of the fresh gas line between the flap and the outlet is provided, and a quantity regulating device with a valve to control the compressed air is also provided. An electronic control unit controls the quantity regulating device and the adjustable flap, so that the fully opened position of the flap corresponds to a fully blocked position of the quantity regulating device.
