Abstract
The invention relates to a device and a method for producing an operating medium for a motor vehicle, especially for use in the exhaust gas post-treatment of the motor vehicle. According to said method, an operating medium is produced from an initial product and air using a catalyst device. Said initial product is heated and mixed with air and the heated mixture of initial product/air is fed to the catalyst device. A part of the initial product is converted to the gaseous phase by means of a preheating element and is entrained by a stream of air when leaving the preheating element, said stream of air leading to a combustion chamber. The method allows to efficiently produce an operating medium, especially a reducing agent for regenerating NOstorage catalysts.
