Just in time to meet tough new EPA NOx rules, the Pilot chain of truck stops announced today that it has opened the first two Diesel Exhaust Fluid pumps in the country.
DEF is for diesel-powered trucks that use urea selective catalytic reduction to meet tough new EPA limits on nitrogen oxide emissions that go into effect on Jan. 1. All new diesels built after that date will have to reduce allowable NOx levels by 90 percent from today’s levels.
DEF is a urea-based solution (32.5 percent industrial urea and 67.5 percent deionized water) that's injected as a fine mist into the engine’s hot exhaust gases. The heat turns the urea into ammonia that – when combined with a special catalytic converter – breaks the NOx down into nitrogen gas and water vapor.
Pilot's DEF pumps are located on both coasts, in Brooks, Ore. and Charlotte, N.C., to service trucks traveling cross country. The DEF is priced at $2.79 a gallon.
Pickup trucks that will require DEF include the 2011 Ford F-Series Super Duty, powered by the all-new 6.7-liter Power Stroke V-8, 2011 Chevrolet Silverado and GMC Sierra HD pickups, powered by the updated 6.6-liter LML Duramax V-8, and 2010 Mahindra TR20 and TR40 midsize pickups, powered by the 2.2-liter mHawk four-cylinder.
The new 2010 Dodge Ram 2500 and 3500 Heavy Duty pickups don't use DEF to scrub NOx because they carry over the existing NOx "adsorber" catalyst that's paired with the 6.7-liter Cummins I6. However, 2010 Dodge Ram 3500, 4500 and 5500 Cab Chassis trucks will use DEF.
DEF will also be available in multiple bottle and canister sizes, so it cab be stored in the vehicle or in a garage. It has a one to two year shelf life, depending on temperature.
Pilot says it will install 100 DEF pumps throughout the U.S. by the middle of 2010.
