Ford/DOE SCR Program Update

Christine  Lambert, Ford Research Labs

Ford Motor Company, with ExxonMobil and FEV, is participating in the Department of Energy’s (DOE) Ultra-Clean Transportation Fuels Program with the goal to develop an innovative emission control system for diesel sport utility vehicles.  The focus on diesel engine emissions is a direct result of the improved volumetric fuel economy (up to 50%) and lower CO2 emissions (up to 25%) over comparable gasoline engines shown in Europe.  Selective Catalytic Reduction (SCR) with aqueous urea as the NOx reductant and a catalyzed Diesel Particulate Filter (DPF) were chosen as the primary emission control system components The program expects to demonstrate more than 90% reduction in particulate matter (PM) and NOx emissions on a light-duty truck/SUV application.  Very low sulfur diesel fuel (~15 ppm) will enable lower PM emissions, reduced fuel economy penalty due to the emission control system and improved long-term system durability.  The end result will allow vehicles with diesel engines to be Tier 2 emissions certified at a minimized cost to the consumer.
