Title: CATALYTIC CONTROL OF EXHAUST EMISSIONS FROM DIESEL AND DUAL FUEL ENGINES
Abstract: Catalytic controls have been used effectively for many years to control toxic emissions from automobile and stationary rich-burning engines. With the passage of the Clean Air Act Amendments of 1990, lean-burning heavy duty engines such as diesel and dual-fuel engines will probably require emissions control. Catalytic technology can be effective in controlling emissions from lean-burning heavy duty engines. A catalytic system was installed in the exhaust stream of a two-cylinder Colt-Pielstick PC2.5 engine to study its system capabilities in reducing NOx, CO, and MHC emissions. The catalyst system comprised a housing containing an oxidation catalyst, a SCR catalyst and an automated ammonia-injection system. The demonstration took place at the Fairbanks Morse test facility in Beliot, Wisconsin. The objective was to achieve 90% NOx reduction with no observable soot formation or degradation in catalyst activity.
