Abstract: The invention relates to a method for controlling and/or adjusting the charging pressure of an exhaust gas turbocharger of an internal combustion engine, the exhaust gas turbocharger having a turbine, a compressor which is driven by the latter and which makes available compressed fluid for the internal combustion engine, and a pressure setting device for setting the turbine inlet pressure. Here, it is provided that the turbine inlet pressure is set to a defined turbine inlet pressure such that for the internal combustion engine there is a maximum indicated medium pressure and/or a maximum effective medium pressure, the defined turbine inlet pressure being computed by means of an air model. The invention furthermore relates to an internal combustion engine with an exhaust gas turbocharger.

Abstract: Cooling circuit for an internal combustion engine 2, having an internal combustion engine with at least one cylinder head and one crankcase, a coolant pump, a primary heat exchanger, and a heat exchanger for an operating medium of the internal combustion engine, the cooling circuit 1 downstream of the coolant pump being divided between a branch site A and a connection site B so that at least one cylinder head is incorporated in a cylinder head branch circuit and the crankcase is incorporated in a crankcase branch circuit and the heat exchanger for an operating medium being located in the cylinder head branch circuit downstream of the at least one cylinder head.
