# Frequently Asked Questions Cummins EPA 2010 Heavy-Duty and MidRange Engines and Products

THE RIGHT PRODUCTS AND THE RIGHT TECHNOLOGY

1. For EPA 2010, what is Cummins Heavy-Duty engine offering?

Cummins ISX15 meets the 2010 EPA standards with a t otally integrated, driverfriendly engine system that delivers better fuel ec onomy with better performance and better reliability. The 2010 ISX15 features ou r exclusive XPI fuel system, the proven VGT TM Turbocharger and Cummins Aftertreatment System tha t includes our proprietary SCR technology. In addition, the I SX15 also incorporates all of the advances from the last 10 years, including the best-in-class 600-bhp

Intebrake TM system, Load-Based Speed Control (LBSC), Gear-Down Protection (GDP) and all the programmable parameters that allo w customers to customize vehicle performance.

In addition to the ISX15 for 2010, Cummins has intr oduced the brand new ISX11.9. The ISX11.9 is a compact engine replacing the 11 liter ISM. The ISX11.9 utilizes common architecture and subsystems with the ISX15 and due to its strong pulling power, excellent throttle respon se and strong clutch engagement torque, it is ideally suited for vocatio nal applications as well as LTL applications and specialty markets.

2. What is Cummins MidRange engine offering for EPA 2010?

For EPA 2010, Cummins offers the ISB6.7, ISC8.3 and ISL9 for medium-duty applications. Customers will notice very few chang es to the MidRange base engines as compared to pre-2010 engines. In fact, customers can expect the same great performance as 2007 engines, coupled wit h best-in-class fuel economy and even better product reliability for 201 0.

Cummins MidRange engines feature the VGT TM Turbocharger, the fully integrated Cummins Aftertreament System, and a comm on ECM across the platforms. In addition, the ISB6.7 features the HP CR fuel system that delivers a precise mixture of fuel and air at constant pressur e, regardless of engine rpm. The ISC8.3 and ISL9 feature the Cummins XPI fuel sy stem – the same technology that is used on the ISX15 – that is capa ble of multiple injection events per cycle at ultra-high injection pressures. With both the HPCR fuel system and the XPI fuel system, customers will enjoy an optima l balance of performance, emissions control and fuel economy.2 Cummins Inc. Rev. 9.12.11 In addition to the ISB6.7, ISC8.3 and ISL9 for EPA 2010, Cummins also offers a natural gas alternative, the 8.9L ISL G. The advan ced alternative fuel engine technology of the ISL G met the EPA 2010 emissions standards in 2007, three years prior to legislation going into effect. To d o so, the ISL G utilizes stoichiometric cooled exhaust gas recirculation (EG R) combustion, leveraging Cummins proven EGR technology to create a high-perf ormance natural gas engine without compromising power and torque.

3. How is Cummins approach to meeting EPA 2010 sta ndards different/better than other engine manufacturers?

Cummins unique capability allows for a complete pac kage that includes a highly capable base engine coupled with the integration of core technologies for fuel systems, air handling, filtration, electronic contr ols and exhaust aftertreatment for both particulate matter (PM) and oxides of nitrogen (NOx). Only Cummins has the key component technologies in-house

.

4. What exactly is Selective Catalytic Reduction ( SCR)?

SCR technology uses a reactant called Diesel Exhaus t Fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions.

5. What is Cummins product experience with SCR?

SCR technology is not new to Cummins. In 2006, Cum mins launched its MidRange engines certified to the Euro 4 standard u sing SCR for commercial vehicle applications in Europe. Cummins has built and shipped over 140,000 SCR based engines to date. Cummins Emission Soluti ons has built and shipped over 380,000 SCR systems.

Prior to full production in January 2010, Cummins h ad accumulated significant experience in Europe and in North America. In fact , more than 80 Cummins field test customers logged more than 8 million miles of testing in real-world applications.

6. What are the benefits of Cummins technology so lution to meet EPA 2010 regulations?

Fuel Economy

is a significant advantage of Cummins technology c hoice to meet

EPA 2010 standards.3 Cummins Inc. Rev. 9.12.11 ■ The Cummins Heavy-Duty ISX15 delivers fuel economy up to 6% better than the industry-leading 2007 ISX, and in some cases ev en more. Compared to an EGR-only solution, the ISX15 delivers up to 10% better fuel economy.

■ The Heavy-Duty ISX11.9 has comparable fuel economy to its predecessor,

the ISM.

■ Cummins Midrange product line up, including the ISB 6.7, ISC8.3 and ISL9, delivers fuel economy improvements of up to 3% bett er than the 2007 MidRange line-up. When compared to MidRange engines with EGR-only technologies, Cummins MidRange engines deliver up t o 20% better fuel efficiency and are competitive with other SCR-based solutions.

Beyond fuel economy improvements, there are many ot her customer benefits with Cummins technology:

Performance. Cummins Heavy-Duty and MidRange products deliver better power and torque than 2007 engines without an incre ase in displacement.

Reliability. When it comes to reliability, experience matters. For Cummins, experience is derived from millions of miles of pro duct testing that occurs in more than 230 test cells around the world, as well as th rough millions of miles of realworld engine use. In fact, Cummins has produced mo re than 140,000 engines utilizing SCR, more than 380,000 SCR systems, 650,0 00 diesel particulate filters, 1 million cooled EGR engines and 3 million VGT TM Turbochargers that are in use in a wide variety of applications, geographies, and climates around the world. And, customers are enjoying the benefits of Cummins experience through improved reliability over our industry-leading 2007 products.4 Cummins Inc. Rev. 9.12.11 7. What is the value of the fuel economy improveme nt to a Cummins

customer?

Heavy Duty Truck Example: Assuming 6 mpg as the base case, at 120,000 miles p er year and diesel fuel at $3.00 per gallon, every 1% improvement in fuel econ omy is worth roughly $600 per truck per year. Therefore, for example, a 6% im provement would be worth approximately $3,400 per truck per year.

9. Is there any impact on the Diesel Particulate F ilter operation on EPA 2010 products?

Cummins improved DPF passive regeneration capabilit y on 2010 products, due to the NOx reduction capabilities of SCR. This res ults in a reduced need for manual stationary regenerations and contributes to the improved fuel economy of the EPA 2010 engine line-up.

CUMMINS AFTERTREATMENT SYSTEM

1) What makes up the Cummins Aftertreatment System ?

There are four major components:

2) What is Diesel Exhaust Fluid (DEF)?

DEF is a 32.5% strength urea-water solution.

3) How much DEF will be required?

DEF consumption is 2 - 3% of fuel consumption depen dent on vehicle operation, geography, and climate.

Selective Catalytic Reduction (SCR)

Catalyst

Cummins Particulate Filter Decomposition Reactor

DEF Dosing Valve6 Cummins Inc. Rev. 9.12.11 4) What size DEF tank is required on a vehicle?

The DEF tank size and location is determined by the vehicle manufacturer/OEM. However, Cummins has provided installation guidelin es to the OEMs and

recommended that the DEF tank size be at least 6% o f the fuel tank volume (i.e. if the fuel tank is a 300 gallon tank, the DEF tank should be at least 18 gallons) In general, the DEF tank size for a medium duty app lication is typically 5 – 15 gallons. For a heavy-duty application the tank siz e is generally 15 – 25 gallons.

5) What happens if the vehicle runs out of DEF?

Aftertreatment Systems that use DEF have two indica tors on the dash that alert the driver to the quantity of DEF on board. First, there is a new DEF gauge very similar to a fuel gauge that indicates the level of DEF (i.e. full, half, quarter, etc.). Second, there is a new DEF low level warning lamp t hat illuminates when the DEF tank has less than 10% DEF remaining.

DEF indicator lamps are designed to illuminate when there is only 10% DEF left in the tank. The lamp will flash when the level dro ps below 5%. There will be a reduction in engine torque performance if the DEF l evel drops below 2.5% and, the vehicle will be limited to 5 MPH maximum speed when started up if the DEF is allowed to go empty.

If the vehicle has not been keyed-off, the engine w ill continue to operate when the DEF has run empty, but the engine power and tor que are significantly

reduced.

Carrying a 1-gallon jug of DEF to top-off the tank will enable operators to drive an additional 200 to 300 miles (322-483 km), so they c an get to a refill location.

Diesel Exhaust Fluid (DEF) - Properties and Handlin g Guidelines

1) Does DEF freeze?

Yes. DEF begins to freeze at 12° F (-11° C). The C ummins Aftertreatment System with SCR is designed to provide heating for the DEF tank and supply lines which reduce the melting time for frozen DEF.

2) How do I keep DEF from freezing? What happens if DEF freezes in the

tank on the vehicle?

During vehicle operation, the SCR system is designe d to provide heating for the DEF tank and supply lines.7 Cummins Inc. Rev. 9.12.11 If DEF freezes when the vehicle is not in operation , start up and normal operation

of the vehicle is not inhibited. Heated lines in th e SCR system are designed to quickly return the DEF to liquid form and the opera tion of the vehicle is not impacted.

3) Does DEF smell?

DEF may have a slightly pungent odor similar to tha t of ammonia.

4) Should I be concerned about handling DEF?

No. DEF is a non-toxic, non-polluting, and non-fla mmable substance. DEF is safe to handle and store and poses no serious risk to humans, animals, equipment or the environment when handled properly.

5) Is DEF available for customers to purchase?

Yes, DEF is available for customers to purchase. S ince 2003, Cummins Filtration has offered DEF in bulk, 330-gallon plas tic totes, 275-gallon disposable totes and 55-gallon plastic drums. In June 2009 th e Fleetguard DEF product line was expanded to include smaller package sizes, incl uding 1 and 2.5 gallon

bottles.

In early 2010 Cummins Filtration and Ashland Consum er Markets (Valvoline) announced an alliance to package, market and distri bute DEF, further expanding the availability of DEF in North America. Since Ap ril 2010 Fleetguard®-

Valvoline® Air Shield TM DEF has been offered through the Cummins and

Valvoline distribution channels in the United State s and Canada.

Outside of Cummins, DEF is available through a wide variety of sources. DEF can be purchased online, at-the-pump at major truck stops, and in small volume containers at more than a thousand retailers throug hout North America.

To help customers find DEF, online tools are availa ble to search for the location of the nearest DEF retailer, such as DiscoverDEF.co m.8 Cummins Inc. Rev. 9.12.11 6) What is the expected price for DEF?

Pricing for DEF is highly dependent on packaging si ze, with bulk pricing being lower than smaller package sizes. Currently, the a t-the-pump price for DEF is $2.79/gallon with bulk pricing below $2.00/gallon i n certain locations.

For more information on pricing or to obtain a quot e for DEF, contact Cummins
