Internal combustion engine for a motor vehicle, and motor vehicle

An internal combustion engine (10) for a motor vehicle, comprising:

• an output shaft via which the motor vehicle is drivable by the combustion engine (10);
• an intake manifold (12) through which air to be fed to a combustion chamber (14) of the combustion engine (10) is flowable;
• an exhaust manifold (16) through which an exhaust gas from the combustion chamber (14) is flowable;
• an exhaust gas aftertreatment device (20) disposed in the exhaust manifold (16) for aftertreating the exhaust gas;
• a heating element (18) disposed in the exhaust manifold (16) upstream of the exhaust gas aftertreatment device (20) for heating a gas flowing through the exhaust manifold (16);
• an electrically assisted exhaust gas turbocharger (22) which has a compressor wheel disposed in the intake manifold (12) as a first impeller (24) for compressing air flowing through the intake manifold (12), a turbine wheel as a second impeller (26) which is disposed in the exhaust manifold (16) and which is drivable by the exhaust gas, and an electric engine via which at least one of the first impeller (24) and second impeller (26) is drivable in a heating mode for heating the exhaust gas aftertreatment device (20), wherein in the heating mode, during which combustion processes in the combustion chamber (14) do not take place and the output shaft is idle, air is conveyable as a heating medium by the at least one of the first impeller (24) and second impeller (26) into the exhaust manifold (16) and is heatable by the heating element (18) in the heating mode to heat the exhaust gas aftertreatment device (20);
• a conduit element (28) that extends inside the exhaust gas turbocharger (22) and through which the heating medium is flowable, wherein via the conduit element (28) at least a part of the heating medium is guidable through the exhaust gas turbocharger (22) from the intake manifold (12) into the exhaust manifold (16);
• and
• an exhaust gas recirculation conduit (36) which is fluidically connected to the exhaust gas manifold (16) at a branch-off point (38) disposed downstream of the second impeller (26) and which is fluidically connected to the intake manifold (12) at an introduction point (40) disposed downstream of the first impeller (24);
• wherein in a fired operation of the internal combustion engine (10), via the exhaust gas recirculation conduit (36), at least a part of the exhaust gas flowing through the exhaust gas manifold (16) is guidable from the branch-off point (38) to the introduction point (40) and is introduced into the intake manifold 12 at the introduction point (40);
• wherein in the heating mode, wherein the internal combustion engine (10) is an idle engine in which combustion processes in the combustion chamber (14) do not take place and the output shaft is idle, at least a part of the heating medium that has been heated by the heating element (18) is guidable from the branch-off point (38) to the introduction point (40) via the exhaust gas recirculation circuit (36) functioning as a recirculation circuit of the heating medium and is guidable via the conduit element (28) through the exhaust gas turbocharger (22) from the intake manifold (12) into the exhaust manifold (16), bypassing the combustion chamber (14), and to the heating element (18) and the exhaust gas aftertreatment device (20) for heating the exhaust gas aftertreatment device (20) when the internal combustion engine (10) is the idle engine.
