Abstract
An exhaust gas system includes an exhaust gas pipe with an integrated evaporator. In order to make the evaporator independent of the site of installation and the mounting position, a capillary structure is arranged between the outer sleeve pipe and the exhaust gas pipe. For increasing the efficiency of the evaporator, vapor grooves are provided in an area of an outer sheath surface of the exhaust gas pipe and fluid grooves are provided in an area of an inner mantle surface of the sleeve pipe.
