Abstract
A charging system () of an internal combustion engine has a compressor () that compresses intake air () to a pressure higher than a boost pressure of the internal combustion engine. A first energy recovery turbine () recovers energy from an exhaust gas mass flow () discharged from a cylinder (). The compressor () and the first energy recovery turbine () are disposed on a first shaft () and the recovered energy is transmitted directly to the compressor (). A cooling turbine () expands and cools the (intake) air () compressed by the compressor () to the boost pressure required by the cylinder (). A second energy recovery turbine () recovers energy from the exhaust gas mass flow (). The second energy recovery turbine () and the cooling turbine () are on a common second shaft (), and the second shaft () is coupled to at least one energy sink.
