A secondary air system 10 is proposed for an internal combustion engine, which has a turbine 11 driven by a pressure gradient in the intake air and a compressor 14 driven by the turbine 11. The turbine is connected by a turbine inlet line 12 and a turbine outlet line 13 to an air intake duct 20. The

A secondary air system 10 is proposed for an internal combustion engine, which has a turbine 11 driven by a pressure gradient in the intake air and a compressor 14 driven by the turbine 11. The turbine is connected by a turbine inlet line 12 and a turbine outlet line 13 to an air intake duct 20. The compressor 14 has a compressor inlet line 15 and a compressor outlet line 16. The cold produced by the turbine 11 is used by a turbine heat exchanger 17 and transport lines 27 for the cooling of, e.g., oil. The heat produced by the compressor 14 is used by a compressor heat exchanger 18 and the transport lines 27 connected thereto, e.g., for heating air.
