Abstract
A vaporization device for a motor vehicle exhaust system vaporizes an oxidizable liquid and introduces a vapor produced from the oxidizable liquid into an exhaust gas flow of the motor vehicle exhaust system. The vaporization device includes a heating element that is arranged in a housing, and which has the form of a glowing filament. The housing has an inlet for the liquid, at least one vaporization chamber, and an outlet for the vapor. The glowing filament is embedded in a glow tube surrounding the glowing filament. The glowing filament and the glow tube constitute a prefabricated unit which is fastened on a side of the housing by the glow tube being mounted directly to the housing. Furthermore, an exhaust system having a vaporization device, and a method of producing a vaporization device are described.
