SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. The internally funded advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NO x ) emissions to meet the California Air Resources Board (CARB) 2027 standards.
