Abstract:
An internal combustion engine system includes a cylinder block with a plurality of cylinders, a gas intake manifold for providing at least air to the cylinder block and an exhaust gas manifold for exiting the exhaust gas from the cylinder block, wherein the exhaust gas manifold includes at least a main exhaust gas outlet and a waste gate exhaust gas outlet, wherein the main exhaust gas outlet is connected to a main exhaust gas pipe for guiding the exhaust gas to a main exhaust gas after treatment system and the waste gate exhaust gas outlet is connected to a waste gate exhaust gas pipe, and wherein the waste gate exhaust gas pipe is reconnected to the main exhaust gas pipe upstream of the main exhaust gas after treatment system and includes at least one waste gate exhaust gas after treatment unit, such as an oxidation catalyst such as a diesel oxidation catalyst, for catalytically treating the exhaust gas streaming through the waste gate exhaust gas pipe, and to a method for increasing the temperature in an internal combustion engine system.
