Device assembly and method for controlling the compressor pressure of a charged combustion engine with fresh air supply device

摘要

The device assembly (1) has a fresh air supplying device (8), which is connected to an outlet of a compressor (11) with an internal combustion engine (6). A controllable valve device (14) is provided, by which the outlet of the compressor is connected with the atmosphere and the inlet of the compressor for controlling the compressed pressure during activating the outlet of the compressor. An independent claim is also included for a method for controlling the compressed pressure of a turbocharged internal combustion engine.
