Patent ID: 8590292

Claim:
A motor vehicle with a system for feeding fluid into another medium, wherein the system comprises: a main container for fluid; a dispensing unit, connected to the main container via a feed line, that dispenses fluid to the other medium, wherein the dispensing unit is coupled to the main container via a return line to feed fluid back thereto, and wherein the dispensing unit is physically and thermally coupled to an exhaust gas treatment unit so that dispensing unit receives heat from the exhaust gas treatment unit; and a further container fluidly accessible by an opening in the feed line, wherein the further container is physically configured so that fluid stored in the further container that is received from the feed line automatically empties from the further container after fluid is no longer provided from the main container to the dispensing unit in such a way that the automatically emptied fluid from the further container passes to the dispensing unit then through the return line and then to the main container so as to cool the dispensing unit.
