Exhaust gas system for a motor vehicle

An exhaust gas system for a motor vehicle, comprising:

• an exhaust gas aftertreatment device;
• an exhaust gas evaporation device communicating fluidically with the exhaust gas aftertreatment device, the exhaust gas aftertreatment device and the exhaust gas evaporation device being arranged in a common housing;
• at least one fastening element provided on the common housing for securing the common housing to a portion of the motor vehicle;
• a connecting line fluidically connecting the exhaust gas aftertreatment device to the exhaust gas evaporation device, the connecting line including a fluid inlet communicating fluidically with the exhaust gas aftertreatment device and a fluid outlet communicating fluidically with the exhaust gas evaporation device;
• an evaporator bypass line, wherein the exhaust gas aftertreatment device communicates fluidically via the evaporator bypass line with a surrounding environment;
• the connecting line and the evaporator bypass line including a valve apparatus arranged adjustable between a first position and a second position, wherein in the first position of the valve apparatus the connecting line is released for communicating a flow through of exhaust gas and the evaporator bypass line is closed, and in the second position the second position of the valve apparatus the connecting line is closed and the evaporator bypass line is released for communicating a flow through of the exhaust gas;
• a butterfly valve in at least one of the connecting line and the evaporator bypass line;
• a dividing wall disposed in the common housing, the dividing wall separating the common housing into a first housing interior space and a second housing interior space;
• the exhaust gas aftertreatment device is arranged in the first housing interior space and the exhaust gas evaporation device is arranged in the second housing interior space;
• a first aperture receiving the connecting line arranged in the dividing wall;
• and a second aperture receiving the bypass connecting line arranged in the dividing wall;
• and
• a third aperture receiving the evaporator bypass line arranged on a housing wall of the second housing interior space, the housing wall disposed opposite of the dividing wall;
• wherein the evaporator bypass line extends through the second housing interior space and is separated fluidically from the second housing interior space.
