    • 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.
    • 提出了一种用于内燃机的二次空气系统10,其具有由进气中的压力梯度驱动的涡轮11和由涡轮11驱动的压缩机14.涡轮机通过涡轮机入口管线12和涡轮机 出口管路13连接到进气管道20.压缩机14具有压缩机入口管线15和压缩机出口管线16.由涡轮机11产生的冷却由涡轮机热交换器17和输送管线27用于冷却, 例如油。 由压缩机14产生的热量由压缩机热交换器18和与其连接的输送线路27使用,例如用于加热空气。
