ABSTRACT:
An internal combustion engine with a 2-stage charge loading includes a connection conduit with a supercharger intercooler provided between the compressors of the low pressure stage and high pressure stage. The supercharger intercooler is configured via a cooling unit in the charge air guiding connection conduit between the compressor of the ATL-low pressure stage and the compressor of the ATL-high pressure stage having a cooling medium flowing therethrough as well as by a specially configured section of the connection conduit. The connection conduit in this section forms with its wall the outer wall of the supercharger intercooler and delimits an air through-put volume sufficient to effect, via a cooling medium flowing through the cooling unit, an acceptable cooling of charge air flowing through the cooling unit that is built into the connection conduit.
