Engine Manufacturers’ Engine Compliance Roundtable June 28 th, 2006

1. FAPT Engine Manufacturers’ Engine Compliance Roundtable June 28th, 2006

2. Al Ambrosini Manager, Engine Marketing International Truck and Engine Corporation

3. Emissions Technology Hardware Strategies • VG Turbo – • CAC – • EGR – • DOC – • DPF –

4. International Exhaust Configurations Temperature Sensor T3 DPF Temperature Sensor T1 DOC Pressure Differential Sensor 3 Bolt Flange Temperature Sensor T2

5. Active Re-Generation • In cylinder dosing • Existing fuel injector adds a “dose” of fuel into the cylinder after the primary combustion has taken place • Unburned fuel is exhausted out of the cylinder down to the DOC where it burns and generates additional heat for the DPF • This additional heat in the DPF helps to convert the soot into ash. Ash has lower volume and back pressure than soot

6. Emissions TechnologyEngine Oil Specifications (CJ-4) • Technical Requirements – Limits on SAPS • Sulfated Ash • Phosphorus • Sulfur • Required to prevent catalyst poisoning and extend DPF service interval • Total Base Number (TBN) will be 8 to 9, whereas CI-4 Plus has a TBN of 10-12. This should be offset with the ULSD • Estimated availability for CJ-4 is October, 2006 • Will be backward compatible with pre-2007 engines

7. Service Strategy for 2007 • No change in oil drain or other service intervals • New engines will require CJ-4 oil • CJ-4 will be backward compatible for older equipment • Older CI-4 oil: • Likely will still be widely available • May be significantly cheaper(Present estimates show CJ-4 to cost anywhere from 15 to 30% more than CI-4)

8. ™ “Always Performing”

9. ™ DT 466 MaxxForce DT

11. MAXXFORCE 5 MAXXFORCE DT MAXXFORCE 7 MAXXFORCE 9 MAXXFORCE 10 MAXXFORCE 11 MAXXFORCE 13 Leading The World In Diesel Engine Technology International Engine Family • Naming will go into effect with 2007 engines • Engines will be black/aluminum in appearance • Badge will retain “Blue” image

12. Stroke Bore Diameter What stayed the same into 2004?

13. What was new in 2004? • Crankcase • Cylinder Head • Crank Shaft • Valve Train • Fuel System • Turbochargers • EGR System If you can point to it, it was new.

14. So Here We Go Again in 2007?

15. What stays the same this time? • Crankcase • Cylinder Head • Crankshaft • Valve Train • Fuel System • Turbocharger If you can point to it, it hasn’t changed (or hasn’t changed much)

16. What’s new? Reliability Improvements • Minor improvements to existing parts for improved reliability and durability • Where possible, these are being launched prior to 2007

17. What’s New? Active Regeneration Strategy • Level One – Adjust parameters to raise exhaust temperature • Level Two – In Cylinder Dosing • Late fuel injection • Fuel exits with exhaust and combusts in DOC • No Additional Hardware or Fuel Lines Required

18. What’s new • Engine Controller • Added capability for control of after-treatment • 32 bit processor • Expanded Features

19. What’s new • Intake Throttle • Helps control active regeneration process • Helps raise exhaust temperature for Active Regeneration • Protects DPF from high temperature damage

20. What’s new • Increased EGR system capacity • Builds upon successful 2004 EGR system • Adds a second EGR cooler on Intake side of engine for NOx emissions reduction

21. What’s new Closed breather • Centrifugal Separator • Driven by Oil Pressure • Very high efficiency • No Service Required • Mounted to crank case • Similar to breather Mack and DDC will offer

22. Molded Foam Wiring Harness • Highest Quality • Robust to chaffing and damage • Easy to assemble and service • Wiring has been a top reliability issue

23. Belt Drive • 10 Groove belt replaces 8 groove • Improves belt life and allows additional accessory loads

24. New Features for 2007 Dual Air Conditioning Compressors from factory • Engine mounted • Uses Sanden “Enhanced” SD7 Compressors (higher volumetric efficiency)

25. New Features for 2007 Top Loading Fuel Strainer • Less Mess • Easy Access

26. 3200 MaxxForce DT 43/4400 MaxxForce DT Product Positioning Characteristics • Configuration I6 • Displacement 7.6L (466 cu in) • Power Output 210 - 300hp @ 2400 – 2600 rpm • Peak Torque 520 – 860 ft lbs. @ 1450 rpm • Aspiration Turbocharged • Combustion System Direct Injection • B10 / B50 Life 300,000 / 450,000 miles • Dry Engine Weight 1480 lbs. RE 73/7400 FE CE

27. ™ MaxxForce DT The same great engines from International

28. Aftertreatment Control SystemUser Interface • Stationary or Forced Regeneration • Interlocks: • To ensure that the driver is in a safe environment and that the driver acknowledges that control of the vehicle will not be available to him until the STATIONARY regeneration is complete, International has devised a series of vehicle level controls to ensure that this procedure is both started and completed accurately • Interlocks include: • Vehicle Speed = 0 • Engine Speed Control NOT engaged • Park Brake SET • Automatic Transmission in NEUTRAL or PARK • Brake Pedal NOT depressed • Clutch Pedal NOT depressed • Throttle Pedal NOT depressed • STATIONARY REGENERATION REQUEST BUTTON PRESSED • If any of these conditions are NOT met, the Request Button will flash, indicating the driver has started the process incorrectly, and the process will NOT start

29. Maximum Exhaust Temp’sCurrent vs. 2007 Diesel Engines DOC • PM reduction (plus HC & CO) • Not an exothermic device • Max Texh = 625C (1150F) at Peak Torque • Idle Texh = 180C (360F) Current Diesel Engine DOC DOC + DPF • DOC is exothermic for regen • DPF filters & stores PM • Max Texh = 650C (1200F) during Regeneration • Idle Texh = 180C (360F) except during regen 2007 Diesel Engine DPF DOC

30. Maximum Exhaust Temperature 2007 Targets • Skin temperatures: • Same as today • Exit exhaust gas temperatures: • Not to exceed 400° C (750° F)
