Kenworth Trucks' expects SCR cost saving of $750 per year

Christopher Goodfellow - 27 October 2010

Engineers at Kenworth Trucks expect the manufacturers choice of Selective Catalytic Reduction (SCR) technology over Exhaust Gas Recirculation (EGR) to save customers $750 per vehicle per year.

Judy McTigue, Director of Market Planning and Research at Kenworth Trucks, told delegates at Integer's Diesel Emissions Conference in San Diego: "We started looking at Selective Catalytic Reduction (SCR) solutions in 2006 and realized in August 2008 that advanced Exhaust Gas Recirculation (EGR) was not going to be viable, this is when we moved the platforms to Selective Catalytic Reduction (SCR)."
The savings are based on $3.00 per Gallon diesel and Diesel Exhaust Fluid (DEF) price, 30,000 per year mileage and six miles per gallon fuel economy (a 5% gain on previous models).
However, McTigue told delegates that the Selective Catalytic Reduction (SCR) solution added between 250 to 500 pounds 2010 model trucks and that consideration had to be given to different customers chassis package needs: "We had to provide a variety of tank options looking at weight sensitivity, fuel tank position and ground clearance, among other factors."
Kenworth's Diesel Exhaust Fluid (DEF) fuel tank options include 5.6 gallon (100 miles capacity), 9 gallon (160 miles), 19 gallon (300 miles) and 27 gallon (5,400 miles).
