An internal combustion engine with an exhaust gas manifold, an exhaust gas line, an exhaust gas turbocharger, by which the compressor provided to charge combustion air for the internal combustion engine is driven, 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. In addition, a first valve is positioned in the section of the exhaust gas line located downstream of the exhaust gas turbocharger in such a way that exhaust gas leaving the exhaust gas turbocharger is diverted into the short-circuit line and then to the power turbine.

Internal combustion engine with exhaust gas turbocharger

In a method for cooling an internal combustion engine, in particular in/on a motor vehicle, it is possible for individual components of the internal combustion engine to be cooled individually, for example a cylinder head and/or a cylinder block, by what is known as a split cooling system. In order to improve the cooling of the components, it is proposed to control the cooling of at least one of the components adaptively.
