In a gas guide system, a combustion engine and a method for operating the engine comprising a gas supply arrangement for supplying gas to the engine, a gas discharge system including an exhaust gas treatment unit for releasing gas from the engine, the gas guide system including a first partial gas discharge line for discharging a first partial gas stream from a first fired cylinder group via the exhaust gas treatment unit and a second gas discharge line for discharging a second partial gas stream from a second unfired cylinder group separately from the hot gas stream directed through the exhaust gas treatment unit to keep it at operating temperatures.

Gas guide system for a combustion engine, a combustion engine and a method for operating the engine

In an internal combustion engine with at least one turbocharger supplying compressed air to the engine cylinders which are divided into a first group and a second group, a first exhaust gas line connecting a first section of an exhaust gas collection line to the turbine, a recirculation line for returning exhaust gas from a second section of the exhaust gas collection line to the charge air supply line, a first control device controls the exhaust gas flow from a section of the cylinders to the first section of the exhaust gas collection line, a second control device controls the exhaust gas flow to the turbine and a third control device controls the exhaust gas flow recirculated to the charge air supply line for the cylinder.
