    摘要： The invention relates to an exhaust gas system (110) of an internal combustion engine, especially of an automobile, comprising a catalyst (113), especially an Nox storage catalyst. A cooling section (112) is provided upstream of the catalyst (113). Said cooling section (112) comprises several separate exhaust gas lines (114) and/or additional cooling means (33; 34; 36) are provided on the cooling section in such a way that in all of the respective operating phases of the internal combustion engine, with different exhaust gas mass flows, a heat energy output from the exhaust gas in relation to the heat energy contained in the exhaust gas (relative heat energy output) increases in such a way that a maximum temperature drop is established for average values of the exhaust gas mass flow.

    摘要： The invention relates to an internal combustion machine, particularly a gasoline engine, having an exhaust gas turbocharger and a mechanical charger (16), wherein a compressor (12) of the exhaust gas turbocharger is disposed upstream of the mechanical charger (16) in the air channel for combustion air. The compressor (12) of the exhaust gas turbocharger is disposed in the air channel for combustion air such that the compressor (12) of the exhaust gas turbocharger draws combustion air directly from an air filter (28), and a first charge air cooler (14) is disposed downstream of the compressor (12) of the exhaust gas turbocharger and upstream of the mechanical charger (16), and a second charge air cooler (22) is disposed downstream of the mechanical charger (16), wherein the first charge air cooler (14), the second charge air cooler (22), the mechanical charger (16), and an air intake (34) are all disposed in a single charge air cooling module, wherein direct fuel injection is provided in combustion chambers of the internal combustion engine for the delivery of fuel.
