Abstract: An internal combustion engine includes: plural cylinders, a first exhaust gas turbocharger having a high-pressure turbine and a high-pressure compressor, a second exhaust gas turbocharger having a low-pressure turbine and a low-pressure compressor, and an SCR catalytic converter positioned between the high-pressure turbine and the low-pressure turbine, via which exhaust gas leaving the high-pressure turbine is conducted upstream of the low-pressure turbine. The low-pressure compressor is assigned a power take-in, via which the low-pressure compressor can be driven when as a consequence of a relatively large exhaust gas temperature drop at the SCR catalytic converter via the low-pressure turbine an adequate amount of energy required to supply the cylinders of the internal combustion engine with a desired quantity of charge air can no longer be provided.
