Exhaust gas turbocharger module and internal combustion engine outfitted therewith

An exhaust gas turbocharger module for an internal combustion engine, comprising:

• a turbocharging assembly that includes:
• a low-pressure exhaust gas turbocharger including a low-pressure turbine and a low-pressure compressor, the low-pressure turbine and the low-pressure compressor having a common first turbocharger axis extending in a first direction;
• a high-pressure exhaust gas turbocharger including a high-pressure turbine and a high-pressure compressor, the high-pressure turbine and the high-pressure compressor having a common second turbocharger axis extending in a second direction, the first and second directions being perpendicular to one another;
• an exhaust gas connection line via which the low-pressure turbine is connected downstream of the high-pressure turbine;
• a charge air connection line via which the high-pressure compressor is connected downstream of the low-pressure compressor;
• and
• a housing shaped to receive the low-pressure turbine, the high-pressure turbine, and the exhaust gas connection line, wherein at least the exhaust gas connection line is arranged with respect to the housing so as to be inside of and surrounded by the housing, wherein the low-pressure compressor, the high-pressure compressor, and the charge air connection line are arranged outside of the housing, and wherein the turbocharging assembly forms the only turbocharging assembly of the exhaust gas turbocharger module,
• wherein the turbocharging assembly includes an exhaust gas bypass line arranged inside the housing and which connects an exhaust gas input of the high-pressure turbine to an exhaust gas input of the low-pressure turbine, and wherein a blocking valve is arranged in the exhaust gas bypass line for selectively opening and closing the exhaust gas bypass line,
• the high-pressure turbine is connected on an input side to an exhaust gas outlet line of the internal combustion engine,
• the high-pressure compressor is connected on an output side to a charge air input line of the internal combustion engine, and
• wherein the charge air connection line extends from the low-pressure compressor to the high-pressure compressor in such a way that an axis defined by the charge air connection line forms a triangle with the first turbocharger axis and the second turbocharger axis in a projection in a common plane with the first turbocharger axis and the second turbocharger axis.
