2 North America On-Highway Standards
5.0 4.5 4.0 EPA ’98 3.5 The two diesel emissions components regulated by the EPA are Nitrogen Oxide (Nox) and Particulate Matter (PM) ’98: electronic controls and electronic controlled fuel systems ’04: Cooled Exhaust Gas Recirculation (Cooled EGR) - involves recirculating a portion of the engine’s exhaust back into the engine at lower temperatures; this lowers the temperature of combustion and subsequently reduces the formation of Nox In ’04 our EGR rate was about 10% ’07: Diesel Particulate Filter (aftertreatment) + increase EGR rates (about 20%) ’10: Selective Catalytic Reduction (SCR) - (additional aftertreatment); oversimplified - there is a lot of optimization in combustion, fuel systems, turbocharging, etc. 3.0 NOx – g/hp-hr 2.5 EPA ’04 2.0 1.5 EPA ’07 1.0 0.5 EPA ’10 0.0 0.0 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.10 0.11 0.12 0.13 Particulate – g/hp-hr

3 The Right Technology Matters September 2007
SCR In-Cylinder Our product development cycle last several years, careful evaluation lead us to two possible options that would meet the more stringent EPA emissions requirement: solution utilizing SCR aftertreatment or staying “in cylinder” primarily through the use of increased rates of EGR September 2007 was when we would publicly communicate our direction Let me show in more detail what happens in the SCR process MidRange Solution SCR Lowest cost of ownership Favorable DEF logistics Heavy-Duty Solution In-cylinder High EGR rates Fuel economy flat with 2007 3

4 Cummins Aftertreatment System
Selective Catalytic Reduction (SCR) Catalyst Decomposition Reactor This slide shows the entire Cummins Aftertreatment System for 2010 The three major components are the: Cummins Particulate Filter Decomposition Reactor which contains the DEF valve The Selective Catalytic Reduction Catalyst The Cummins Aftertreatment system reduces Oxides of Nitrogen and Particulate Matter to achieve near-zero emissions standards SCR uses a chemical called Diesel Exhaust Fluid (DEF) and a SCR catalytic converter to significantly reduce nitrogen oxide (NOx) emissions in diesel engines.

5 The Right Technology Matters September 2007
SCR In-Cylinder In 2007, Cummins originally announced our technology path for At that time, as we still do today, we evaluate the Right Technology for the Right Customer Needs. Cummins chose Selective Catalytic Reduction, or SCR technology for Midrange engines - which include the ISB, ISC and the 9 leader ISL. At that time, our direction for heavy duty engines was an in-cylinder approach. MidRange Solution SCR Lowest cost of ownership Favorable DEF logistics Heavy-Duty Solution In-cylinder High EGR rates Fuel economy flat with 2007 5

6 Challenges With In-Cylinder NOx Control
High EGR rates: increased risk of EGR condensation Power cylinder corrosion; water in oil Reliability and durability High EGR rates: high heat rejection 5 - 9% fuel economy disadvantage Increased DPF regenerations Power density and torque limitations Throttle response and drivability Cummins was going down the in-cylinder path and experienced Many Challenges with an in-cylinder solution Would have lost the fuel economy leadership our customers have come to expect Higher EGR rates means higher heat rejection. This would require changes to the cooling package - not good news for body builders The risk of EGR condensation could lead to water in oil and power cylinder corrosion. Simply stated, it’s a risk to reliability. Cummins is able to maintain ALL ratings from current product without the need to increase displacement. An SCR Solution allows drivers with various levels of experience to 6

7 The Right Technology Matters August 2008
MidRange And Heavy-Duty Solution 5 - 9% fuel economy advantage over in-cylinder Lower than 2007 levels of EGR Superior performance Lowest cost of ownership Low DEF consumption (2%) Single VGT Turbocharger Installation impact minimized Consistent technology through the emissions cycle SCR Last year, we announced publicly that all our heavy-duty engines would now also incorporate SCR technology 7

10 The Facts about the Fluid - DEF Properties
It is a solution comprised of: 32.5% automotive grade urea 67.5% deionized water DEF is safe to handle and store Non-toxic Non-polluting Non-flammable DEF freezes at 12° F (-11° C) Frozen DEF does not impact start up and normal operation of the vehicle So now let’s take a look at the Facts about the Fluid. First we have the properties of DEF. DEF is safe to handle and store, it is non-toxic, non-polluting, and non-flammable. DEF does freeze at 11F but it is important to note that frozen DEF does not impact the start-up or operation of the vehicle. When stored or exposed to extreme temperatures, neither DEF nor Urea become toxic. Finally, DEF has a pH of approximately 9.
