SCR Emission Control Technology: Closed-Loop Dosing Architecture and Catalyst Chemistry

Selective Catalytic Reduction has become the dominant technology for managing post-combustion emissions in heavy-duty diesel engines. Unlike older exhaust gas recirculation (EGR) methods that attempt to reduce emissions inside the engine cylinder at the expense of fuel efficiency, SCR emission control technology treats pollutants in the exhaust pipe, allowing engineers to tune engines for...
