A combustion engine for a motor vehicle includes an output shaft, an intake tract, an exhaust gas tract, an exhaust gas aftertreatment device disposed in the exhaust gas tract, a heating element disposed in the exhaust gas tract upstream of the exhaust gas aftertreatment device, an electrically assisted exhaust gas turbocharger, and a conduit element which is fluidically connected to the exhaust gas tract at a first connection point disposed downstream of the exhaust gas aftertreatment device and at a second connection point disposed upstream of the heating element.

Combustion engine for a motor vehicle, and motor vehicle

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.

Internal combustion engine for a motor vehicle, and motor vehicle

An internal combustion engine for a motor vehicle includes a drive shaft, an intake tract, an exhaust gas tract, an exhaust gas aftertreatment device disposed in the exhaust gas tract, a heating element disposed in the exhaust gas tract upstream of the exhaust gas aftertreatment device, an electrically assisted exhaust gas turbocharger, and a conduit element which is fluidically connected to the exhaust gas tract at a first connection point disposed downstream of the exhaust gas aftertreatment device and at a second connection point disposed upstream of the heating element.

Internal combustion engine for a motor vehicle and motor vehicle

In an internal combustion engine and a method of operation the internal combustion engine which includes a high pressure and a low pressure turbocharger having exhaust gas turbines arranged in series in an engine exhaust line provided with a high pressure exhaust gas recirculation line and a low pressure exhaust gas recirculation line via which exhaust gas can be conducted to an inlet line of the engine, the arrangement is switchable depending on the engine speed between an exhaust gas recirculation by way of the high pressure line and an exhaust gas recirculation by way of both, the high pressure and the low pressure line, to achieve low emissions and low fuel consumption.
