Internal combustion engine with exhaust after treatment and method for operating such an internal combustion engine

The invention relates to an internal combustion engine (1) with at least one cylinder head (2) with at least one cylinder (3), in which - each cylinder (3) has at least one inlet opening (10) for supplying the air via the intake system (12), - each cylinder (3) at least one outlet (4) for discharging the exhaust gases via Abgasabfuhrsystem (6), wherein at each outlet opening (4) connecting an exhaust pipe (5) and the Abgasabfuhrsystem (6) is limited by at least one wall and formed is - in order to exhaust aftertreatment at least one exhaust after-treatment system (9) is provided in Abgasabfuhrsystem (6), and - upstream of the at least one exhaust after-treatment system (9) at least one turbine (8a) in Abgasabfuhrsystem (6) is arranged, wherein the turbine housing having a turbine (8a) comprises at least one supported in the turbine casing on a rotatable shaft impeller. It is to be an internal combustion engine (1) is provided which is improved in the exhaust gas aftertreatment. This object is solved by an internal combustion engine (1) of the type mentioned, which is characterized in that - the at least one the Abgasabfuhrsystem (6) restricting wall upstream of the at least one exhaust after-treatment system (9) at least partially with at least one electrical heating device (13) for heating the Abgasabfuhrsystems (6) and the exhaust gas is provided.
