Common Terms•SCR = Selective Catalytic Reduction

A vehicle emissions control technology to reduce diesel engine emissions for passenger cars, light & heavy duty trucks. Reduces NOx using a reducing agent by converting NOx into nitrogen, water and tiny amounts of carbon dioxide.

•DEF = Diesel Exhaust FluidA solution of 32.5% automotive-grade urea and 67.5% purified water used in the SCR process; also referred to as AUS32

What Does That Mean?

•DPF = Diesel Particulate FilterAdditional Aftertreatment hardware added to truck in 2007 to reduce the amount of Particulate Matter in the vehicle’s exhaust

How Far Can You Go?

SCR101 Summary

• Selective Catalytic Reduction (SCR) Is… •The most efficient way to meet 2010 emissions

•Simple for truckers to operate and maintain•Already in use today and heavily tested in the United States

•Diesel Exhaust Fluid (DEF) Is…•Easy and economical to purchase and simple to use

Department 21

Is DEF unsafe to handle? Is it flammable or hazardous?

Material Safety Data Sheet (MSDS)• Hazards Identification “Urea Solution is not Flammable”•First Aid Measures“Wash area thoroughly with soap and water”•Fire Fighting Measures“Urea solution is not flammable”•Transportation Information“Urea solution is not listed by any US or Canadian transportation authority as a hazardous material…”

Department 22

Does DEF become toxic at extremely high temperatures?

“Urea does not become toxic at any temperature”“…at 122°F, DEF will still meet ISO specifications of less than 0.2% ammonia for at least 35 days. At that rate it would take more than 2 years to reach the ammonia level of household ammonia which is still not classified as toxic” James Spooner VP & GM Colonial Chemical Company

Department 23

Will DEF freeze at 12°F?

DEF will start to freeze at 12°F

Engine coolant is used to thaw DEF in tank. System

will function until DEF begins to flow.

EPA Requires DEF flow within 70 minutes

DEF is available through a variety of distribution networks today, at affordable prices.

Detroit Diesel Test Fleet June 23, 2009: 275 Gallons @ $2.42/gal

TA Saginaw, MI June 26, 2009 2.5 Gallons @ $3.99/gal

Will I be able to get DEF at a reasonable price?

Pilot Travel Center Brooks, OR Sept 14, 2009

Fuel Island Bulk Fill @ $2.79/gal

Department 26

If I run out of DEF will my truck still start?

When the DEF tank is empty “…the vehicle will be limited to 5 mph with inducement notification”

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY

NATIONAL VEHICLE AND FUEL EMISSIONS LABORATORY

SUBJECT: Certification Requirements for Heavy-Duty Diesel Engines Using Selective Catalyst Reduction (SCR) Technologies

The DEF gauge indicates the level of DEF in the tank and has a series of alerts when the tank is running low
