ABSTRACT:
A method is described for managing vapors generated from an ammonia-containing reductant delivery system. The method may include generating ammonia vapors in a first storage device and storing said generated ammonia vapors in a second storage device. Further, the method may include purging the stored vapors from the second storage device to upstream of a combustion chamber of the engine during a first condition and downstream of the combustion chamber during a second condition.
