Embodiment Construction
[0039] figure 1 An engine system 1 is shown with an internal combustion engine 2 , which generally includes a plurality of cylinders 3 . The internal combustion engine 2 can operate according to the four-stroke principle and can be designed in particular as a fuel-using internal combustion engine, in particular as a diesel engine.
[0040] Fresh air is supplied to cylinders 3 of internal combustion engine 2 via an intake system 4 . During operation, fuel is injected into the combustion chambers of the cylinders 3 according to the load requirements, after combustion of which the combustion exhaust gases are discharged via exhaust gas outlets 5 .
[0041] An exhaust gas-driven charging device 6 is arranged in the intake system 4 and in the exhaust gas outlet 5 . The charging device 6 comprises a turbine 61 which is arranged in the exhaust gas outlet 5 and serves to convert the exhaust gas enthalpy of the combustion exhaust gas into mechanical energy. Furthermore, a compressor...
