Strategic Plan for Emission Compliance

Daimler Trucks

SCR Technical Approach - System Integration

•Allow engine out emission level to increase

•Optimize engine performance and maintenance

•Reduce soot loading of particulate filter

•Control NOx emissions with Aftertreatment

Why SCR Works

Daimler Trucks 4

= Exhaust

SCR Catalyst

NOx

PM

NOx

Particulate Matter (PM) is trapped

in the Diesel Particulate Filter

(DPF)

= Diesel Exhaust Fluid (DEF)

PM

DEF injected into the

exhaust stream

DEF

NH3DEF solution „hydrolyzes‟ into

ammonia gas (NH3) which mixes

with the exhaust

Ammonia (NH3) and Nitrogen

Oxides (NOx) react in the catalyst

to form Nitrogen and Water

N2H2O

Exhaust leaves the engine with

the pollutants NOx and PM

How SCR Works

Fuel efficiency gains are a result of the

emission reduction process occurring downstream

2010 Fuel Economy

• Using BlueTec means:

• Up to 5% fuel economy advantage

over a comparable EPA07 engine,

• DEF consumption expected to be 2%

• Net fuel economy advantage = 3%

• There has NEVER been an emissions

solution that improves fuel economy

until now….

Economy Back to

Pre-EGR Levels

2010 Fuel Economy

In 2010, Detroit Diesel engines will go 45-90 hours between particulate

filter regenerations.

EPA „07 DD engines regenerate every

Our 2010 engines will regenerate less

often reducing the fuel economy penalty

The following diagram illustrates the flow of exhaust through the DOC and DPF. Then where the DEF

enters the hydrolysis pipe and eventually meets the exhaust in the SCR device. Detroit Diesel’s dual

parallel flow (ATD & SCR catalyst) reduces backpressure on the engine thus increasing fuel efficiency.

SCR Equipment

DDC’s own unique approach to SCR includes

some new major components for 2010:

• 1-Box or 2-Box contains ATD & SCR

catalyst

• DEF plastic storage tank

(6, 13, 23 gallon sizes)

• Aftertreatment Control Module

(ACM)

DEF Tanks

Cold Weather Operation:

• Tanks are engine coolant heated

• DEF delivery lines are electrically heated

Fill necks do not allow

insertion of diesel nozzle into

DEF tank (magnetic lock

option being developed)

Specifications / Packaging

The DEF tank, 1-Box configuration (or 2-Box configuration), Aftertreatment Control Module (ACM)

as well as some supporting hardware are engineered to fit efficiently into the chassis. Notice how

seamlessly the 1-box SCR system fits into the chassis.
