Abstract

An internal combustion engine for a motor vehicle includes an exhaust system through which exhaust gas can flow and in which a first exhaust gas aftertreatment element is disposed. An exhaust gas turbocharger has a turbine and the turbine has a turbine wheel which is disposed upstream of the first exhaust gas aftertreatment element. A bypass line bypasses the turbine wheel and via the bypass line at least part of the exhaust gas can bypass the turbine wheel. The bypass line also bypasses the first exhaust gas aftertreatment element. The bypass line is fluidically connected to the exhaust system at a branch point disposed upstream of the turbine wheel and upstream of the first exhaust gas aftertreatment element. The bypass line is fluidically connected to the exhaust system at a discharge point disposed downstream of the turbine wheel and downstream of the first exhaust gas aftertreatment element.
