Abstract

An exhaust gas system for a motor vehicle may include an exhaust gas aftertreatment device communicating fluidically with an exhaust gas evaporation device. The exhaust gas aftertreatment device and the exhaust gas evaporation device may be arranged in one or more housings. A connecting line may be provided to fluidically connect the exhaust gas aftertreatment device to the exhaust gas evaporation device. The connecting line may include a fluid inlet connected to the exhaust gas aftertreatment device and a fluid outlet connected to the exhaust gas evaporation device. An evaporation bypass line may branch off from the connection line at a branching-off point. A valve apparatus may be arranged in at least the connecting line and may be adjustable between a first position to fluidly connect the fluid inlet to the fluid outlet, and a second position to fluidly connect the fluid inlet to the evaporator bypass line.
