Abstract:
1. An internal combustion engine comprising: an exhaust gas manifold; an exhaust gas line; an exhaust gas turbocharger that is configured to drive a compressor that is provided to charge combustion air for the internal combustion engine; and a bypass line, which branches from the exhaust gas line and in which a power turbine is arranged, wherein a short-circuit line branches from the bypass line and leads to a section of the exhaust gas line located downstream of the exhaust gas turbocharger, wherein a first valve is positioned in the section of the exhaust gas line located downstream of the exhaust gas turbocharger such that exhaust gas leaving the exhaust gas turbocharger is diverted into the short-circuit line and then to the power turbine, wherein the exhaust gas line extends between and connects the exhaust gas manifold and the exhaust gas turbocharger, wherein a second valve, which is positioned upstream of the compressor, is configured to divert the exhaust gas into the bypass line so that the exhaust gas bypasses the compressor.
