22 Years of Truck Emission Changes

We’ve Come a Long Way

1988

Particulate Matter - PM (g/bhp-hr)

By 2010, 65 trucks will emit the same amount of Pollutants as 1 truck did in 1988

Nitrogen Oxides - NOx (g/bhp-hr)

what does that mean
Department What Does That Mean?

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.
  • BlueTec
    • Daimler’s branded SCR emissions technology

32.5% Urea

100% DEF

Diesel

Exhaust

Fluid

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

67.5%

Water

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

How SCR Works: Cleaning the Air After the Engine

Exhaust leaves the engine with

the pollutants NOx and PM

= Exhaust

= Diesel Exhaust Fluid (DEF)

Particulate Matter (PM) is trapped

in the Diesel Particulate Filter

Ammonia (NH3) and Nitrogen

ammonia gas (NH3) which mixes

with the exhaust

Experience for SCR

  • SCR has Experience all over the World…Over 600,000 Trucks in operation
  • SCR 2010 Test Fleet Have Performed Extremely Well
  • Detroit Diesel Launched Our 2010 Engine in 2007…Tried and True With Nearly 2 Billion Customer Miles Already

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

Question:

Answer: NO

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…”
slide22
Department

Question:

Answer: NO

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

slide23
Department

Question:

Answer: YES

Will DEF freeze at 12°F?

Engine coolant is used to thaw DEF in tank. System will function until DEF begins to flow.

DEF will start to freeze at 12°F

EPA Requires DEF flow within 70 minutes

Question:

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

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

Answer: YES

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

Pilot Travel Center Brooks, OR Sept 14, 2009 Fuel Island Bulk Fill @ $2.79/gal

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

slide26

Question:

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

Answer: YES

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

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

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