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.

Abstract: A method for operating an exhaust gas post-treatment device for an internal combustion engine. The exhaust gas post-treatment device has an oxidation catalyst having a catalytic coating, a heating element upstream of the oxidation catalyst or a heating element provided with the catalytic coating with which heat energy can be introduced actively into the exhaust system at a heating point. The exhaust gas post-treatment device further has a dosing element with which a reducing agent can be introduced into the exhaust gas at an introduction point arranged downstream of the oxidation catalyst and has an SCR system arranged downstream of the introduction point. The method provides checking whether target temperatures have been reached in the exhaust gas system. If the target temperatures are fallen short of, the target temperatures can be reached within a defined period of time by using the heating element and by carrying out a post-injection.
