Abstract
A system is described for storing ammonia and injecting it into the exhaust gas stream of an engine to reduce nitrogen oxides. The ammonia is stored as a liquid mixture () of ammonia and water in a container (). In one system, the mixture passes through a tube with a portion () in contact with the exhaust gas pipe () to heat the mixture and separate the ammonia from the water, with the ammonia being further heated at a nozzle () to activate the ammonia before injection into an upstream portion of the exhaust gas pipe.
