Abstract: A system may include a urea injection device, first, second and third conduits and a valve. The first conduit may contain a fluid and may be in heat transfer relation with the urea injection device. The second conduit may be in selective fluid communication with the first conduit. The third conduit may be in selective fluid communication with the first conduit and in heat transfer relation with a heat source. The valve may be connected to the first, second and third conduits and may be movable between first and second positions. The first position may allow fluid communication between the first and third conduits and restrict communication between the first and second conduits. The second position may allow fluid communication between the first and second conduits and restrict fluid communication between the first and third conduits.

Abstract: A retaining bracket for holding conduits may employ a first half or stationary portion defining a semi-circular first conduit holding portion and a semi-circular second conduit holding portion. A second half or movable portion may be foldable onto the stationary portion such that a first arcuate groove and a second arcuate groove of the movable portion match the first and second conduit holding portions, respectively, to accommodate the cylindrical conduits. A first rigid binder piece may contact a long side of the stationary portion and attach to a first compressible insert and a second compressible insert. The first compressible insert may reside within the first conduit holding portion and the second compressible insert may reside within the second conduit holding portion and compress against the conduits, respectively. The binder and inserts may install into the retain bracket before or after the movable portion is closed onto the stationary portion.
