EPA07 Impacted All Mack Products

EPA 2010 Mandate

Effective January 1, 2010 all heavy duty diesel truck engines

produced for sale in North America must meet the EPA 2010

emissions regulations:

– 83% reduction in NOx

– No reduction in particulates compared to 2007.

– The technical solution will build upon the US07 engine and Diesel

Particulate Filters (DPF).

– Addition of Selective Catalytic Reduction (SCR)

– Diesel Exhaust Fluid (DEF)

– On Board Diagnostics (OBD).

Diesel Exhaust Fluid

• Currently available at dealer locations and truck stops.

• Our supplier, TerraCair has acquired licensing rights for a

form of DEF that will not freeze at temperatures as low as

-30 C.

• The consumption rate of DEF is 2 to 3% of the diesel fuel

consumption rate.

• There is no delay in driving a truck with a frozen

DEF tank.

Diesel Exhaust Fluid

• DEF is not a hazardous substance.

• There are no known health hazards related

to handling DEF.

• Material safety data sheets available from

suppliers provides more information on

handling of urea.

• No restrictions for transports on rail, road or

ships.

Even in 1998 we knew…

Diesel Fuel should be sipped!

Here is just ONE of many very good reasons for SCR:

FUEL ECONOMY

Emission Facts: Average Carbon

Dioxide Emissions Resulting from

Diesel Fuel

CO2 emissions from a gallon of diesel

= 10.1 kg/gallon

= 22.2 pounds/gallon

MR 633 LNG

Natural Gas

• Meets US ’10 Emissions regulations

• Reduced dependency on foreign oil

• Lower fuel costs

• Lower CO2 emissions

• Land Fill Gas / Biomethane capable

• Three way catalyst – Does not require DPF or SCR

• Quieter engine operation ( residential )

• Well suited for trucks that return home every night
