Abstract:
1. Internal combustion engine having an exhaust gas turbocharger and an exhaust gas recirculation device, whereby the internal combustion engine has a plurality of cylinders and each cylinder of the internal combustion engine has at least one intake valve and at least one outlet valve, and a compressor of the exhaust gas turbocharger is assigned to an inlet and an asymmetrical exhaust gas turbine of the exhaust gas turbocharger is assigned to an outlet of the internal combustion engine; the compressor is connected to the inlet via a charge air line; the exhaust gas turbine has two intake ports with different flow cross sections that are separated by a partition, each intake port being connected to the outlet through its own exhaust gas inlet line, whereby each exhaust gas inlet line is assigned a partial number of cylinders of the internal combustion engine, and an exhaust gas recirculation line leads from the exhaust gas inlet line of the intake port having the smaller flow cross section to the charge air line, wherein the distribution of the recirculated exhaust among the individual cylinders of the internal combustion engine is different, whereby a partial number of the cylinders of the internal combustion engine receives all or most of the recirculated exhaust, and the remaining cylinders receive little or none of the recirculated exhaust.
