Abstract: An internal combustion engine for a motor vehicle includes an output shaft, an intake manifold, an exhaust manifold, an exhaust gas aftertreatment device disposed in the exhaust manifold, a heating element disposed in the exhaust manifold upstream of the exhaust gas aftertreatment device, an electrically assisted exhaust gas turbocharger, and a conduit element that extends inside the exhaust gas turbocharger and through which a heating medium is flowable. Via the conduit element at least a part of the heating medium is guidable through the exhaust gas turbocharger from the intake manifold into the exhaust manifold.
