Christian Dahlheim, Maximilian Fleischer, Hans Meixner: Method for reducing the nitrogen oxide concentration in the exhaust of an internal combustion engine or of a firing system. Siemens Aktiengesellschaft, Hill Steadman & Simpson, July 30, 1996: US05540047 (52 worldwide citation)

The method reduces the nitrogen oxide concentration in the exhaust of an internal combustion engine. A noticeable reduction in the NO.sub.x emission of a diesel motor can be achieved by applying the Selective Catalytic Reduction (SCR) method. In this method, ammonia is injected into a catalyzer thro ...
