Abstract: A method is provided for operating an internal combustion engine, which comprises at least one combustion unit, a fresh gas tract for supplying fresh gas to the combustion unit, and a fuel tank system. A fresh gas compressor as well as a differential pressure valve are integrated into the fresh gas tract. The first purge gas line opens into a first section of the fresh gas tract, which is situated downstream from the differential pressure valve as well as upstream from the fresh gas compressor, while the second purge gas line opens into a second section of the fresh gas tract situated downstream from the fresh gas compressor. The differential pressure valve is at least partially closed at least temporarily during an intake mode of the internal combustion engine with fuel vapor filter purging, and purge gas is introduced into the fresh gas tract via the first purge gas line.

Abstract: The invention relates to a power electronics module including a first circuit carrier (5,10, 11), as well as an electronic assembly (20, 30) arranged in an electrically contacting manner on the upper flat side of the first circuit carrier (5, 10, 11), and a first cooling element (40) in thermal contact with the underside of the first circuit carrier (5, 10, 11), wherein the module has at least one second assembly (20, 30) arranged on the upper side of a second circuit carrier (5, 10, 11) and a second cooling element (40) arranged on the underside of the second circuit carrier (5, 10, 11), wherein the first and the second circuit carriers (5, 10, 11) are arranged with their upper sides facing one another and at least one central heat sink (60, 61, 63, 64) that is electrically insulated from the assemblies (20, 30) is arranged in the space between the assemblies (20, 30), wherein the assemblies (20, 30) and the at least one central heat sink (60, 61, 63, 64) are embedded in a heat-conducting potting compound (5

Abstract: The invention relates to a power electronics module including a flat circuit carrier (5) and an electronic assembly (10) arranged in an electrically contacting manner on the upper flat side of the circuit carrier (5) and cooling bodies (20) thermally in contact with the underside of the circuit carrier (5), wherein a heat-conducting bridge (30) arranged on the upper side of the circuit carrier (5), spanning the assembly (10) and extensively covering same, wherein the heat-conducting bridge (30) is in thermal contact with the cooling body (20) at mounting points arranged next to the assembly (10) and the space between the heat-conducting bridge (30) and the circuit carrier (5) is filled with a heat-conducting potting compound (50).
