Abstract: A method and a system for cooling an internal combustion engine having charge air feed, which has a first and a second cooling loop, of which the first cooling loop is operated at a higher temperature level than the second cooling loop, and in which the charge air feed has at least one intercooling unit which is thermally coupled to the second cooling loop, having a controllable coolant throughput. The system includes at least one shutdown element in the second cooling loop for throttling the coolant throughput in the second cooling loop to 0 (zero). Coolant throughput may be shut down during the operation of the internal combustion engine as a function of an operating parameter of a vehicle component.

Abstract: A method and a system for cooling an internal combustion engine (3) having charge air feed, which has a first (1) and a second (2) cooling loop, of which the first cooling loop (1) is operated at a higher temperature level than the second cooling loop (2), and in which the charge air feed has at least one intercooling unit (9) which is thermally coupled to the second cooling loop (2), having a controllable coolant throughput. The system includes at least one shutdown element (13) in the second cooling loop (2) for throttling the coolant throughput in the second cooling loop (2) to 0 (zero), i.e., the coolant throughput may be shut down during the operation of the internal combustion engine (3) as a function of an operating parameter of a vehicle component.

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.

Abstract: The invention relates to an internal combustion engine with a 2-stage charge loading. A connection conduit (13) with a supercharger intercooler (14) is provided between the compressor of the low pressure stage and that of the high pressure stage.
