CLEARING THE AIR ON 2007 EMISSIONS Leading The World In Diesel Engine Technology 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

CLEARING THE AIR ON 2007 EMISSIONS Leading The World In Diesel Engine Technology Emissions Technology Engine 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 This should be offset with the ULSD Estimated availability for CJ-4 is October, 2006 Will be backward compatible with pre-2007 engines

CLEARING THE AIR ON 2007 EMISSIONS Leading The World In Diesel Engine Technology 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)

CLEARING THE AIR ON 2007 EMISSIONS Leading The World In Diesel Engine Technology Aftertreatment Control System User Interface Passive Regeneration – No driver Notification Active Regeneration – No driver Notification Forced or Manual Regeneration – Driver must be notified –This mode is not available to the driver during the normal driving cycle and requires additional vehicle level logic to work with the engine and aftertreatment controls to start the regeneration. This mode is performed in a standstill operation. –But what if I cannot perform this process now? The vehicle will allow a certain amount of time before this process MUST be started. Additional warning levels and feedback will be provided to the driver to ensure that the filter and engine do not become damaged including de-rate of the engine to protect these sensitive systems

CLEARING THE AIR ON 2007 EMISSIONS Leading The World In Diesel Engine Technology 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 Aftertreatment Control System User Interface
