2 DaimlerChrysler Truck Group Aftertreatment System (ATS) Diesel Particulate Filter (DPF) Diesel Oxidation Catalyst (DOC) Intake Throttle Valve TT T P Aftertreatment Device (ATD) Diesel Particulate Filter (DPF) Diesel Oxidation Catalyst (DOC) Doser Intake throttle DDEC VI controls Doser Aftertreatment System

3 DaimlerChrysler Truck Group Aftertreatment Regeneration Animation Aftertreatment System

4 DaimlerChrysler Truck Group Passive Regeneration Passive regeneration occurs when the exhaust temperature during normal operation is adequate to trigger regeneration (600ºF - 750ºF) During normal driving mode the soot is regenerated without driver intervention Intake throttle valve may be used to increase passive regeneration without the aid of dosing Aftertreatment System

5 DaimlerChrysler Truck Group Active Regeneration Active regeneration takes place when normal operation does not allow for passive regeneration to take place DDEC VI uses the doser and intake throttle valve to elevate exhaust temperatures allowing for complete regeneration Active regeneration just like passive regeneration does not require driver intervention Regeneration is suspended when the vehicle drops below a minimum threshold (~5 mph) for S60/MB4000. MB900 Engines will regenerate down to 0 mph. If vehicle slows below a minimum threshold during an active regeneration a high exhaust temp lamp will illuminate until exhaust temperature drops below 750ºF Aftertreatment System

6 DaimlerChrysler Truck Group Stationary or Parked Regeneration In a small number of select engine duty cycles completion of an active/passive regeneration may not be possible. In these cases, a stationary regeneration will need to occur The DPF lamp has been added to inform the driver that a stationary regeneration needs to take place The operator will be alerted hours before a stationary regeneration MUST take place. The operator should perform the stationary regeneration as soon as possible after the light is illuminated. To complete a stationary regeneration the following conditions must be met Vehicle must be in park Clutch is depressed and released Transmission must be in neutral/park Once initiated by the driver, active regeneration takes roughly 20 minutes to complete DDC expects stationary regeneration will be required in less than 5% of customer applications Aftertreatment System

7 DaimlerChrysler Truck Group Regeneration Strategy Vocational Applications PASSIVE ACTIVE STATIONARY PARKED Vocational Applications may require stationary or Parked regenerations under light-load conditions No Driver Effort Required Aftertreatment System

8 DaimlerChrysler Truck Group NO DRIVER INTERACTION REQUIRED, FILTER CLEANING (also called regeneration) IS FULLY AUTOMATIC. You will only see warning lights if the filter cannot perform an automatic cleaning. The DPF is in self cleaning mode. No driver interaction is required. Driver cannot tell if system is Passively or Actively regenerating. When the regeneration process is complete the timers are all reset to zero and the process starts again. Driver will only see warning lamps if the filter cannot perform an automatic cleaning (regeneration). The DPF Regeneration Cycle

9 DaimlerChrysler Truck Group SOLID A parked regeneration can be performed at any time when the DPF lamp is on. The engine will continue to try and complete an active regeneration during this time. Lamp will begin flashing after approximately 1 hour of driving time if an over-the-road regeneration cannot be completed. If regeneration is completed, lamp will go out and all timers will be reset to zero. The DPF Regeneration Cycle Bring vehicle to highway speeds to allow for an Automatic Regeneration OR Perform a Parked Regeneration. FILTER REGENERATION RECOMMENDED.

10 DaimlerChrysler Truck Group FLASHING A parked regeneration should now be performed as soon as possible. The engine will continue to try and complete an active regeneration during this time. Check Engine Lamp will come on after approximately 1/2 hour of driving time if an over-the-road regeneration cannot be completed. If regeneration is completed, lamp will go out and all timers will be reset to zero. The DPF Regeneration Cycle Bring vehicle to highway speeds to allow for an Automatic Regeneration OR Perform a Parked Regeneration as soon as possible. FILTER REGENERATION NECESSARY.

11 DaimlerChrysler Truck Group + FLASHING A parked regeneration MUST now be performed. The engine will NOT try and complete an active regeneration during this time. Engine is derated by 25%. Stop Engine Lamp will come on after approximately: 1 hour of driving time for MBE 900. The DPF Regeneration Cycle Vehicle must be parked and a Parked Regeneration OR Service Regeneration must be performed. PARKED REGENERATION REQUIRED – ENGINE DERATE.

12 DaimlerChrysler Truck Group + + FLASHING The DPF Regeneration Cycle A parked regeneration MUST now be performed. The engine shutdown over ride switch functions normally. (the number of over-rides is recorded) Vehicle must be parked and a Parked Regeneration OR Service Regeneration must be performed. PARKED REGENERATION REQUIRED – ENGINE SHUTDOWN.

13 DaimlerChrysler Truck Group High Idle Regeneration Procedures DPF Regeneration Lamp Light On Solid Aftertreatment System From Time to Time The Yellow DPF Regeneration Lamp May Come On This Indicates that Soot Level is Elevated Driving on the Highway or Having the Engine Under Load will Allow the Filter to Self-Clean If the Light Starts to Flash you Will need to Pull the Truck Over and Initiate a High Idle Regeneration

14 DaimlerChrysler Truck Group High Idle Regeneration Procedures DPF Regeneration Lamp Light Flashing Aftertreatment System The Engine Needs to be Warm (Approximately 180F) It is Best to do This Immediately After Stopping With the Truck Running, Set Park Brake Put Transmission in Neutral Depress & Release Clutch Pedal Verify No Other Codes in System (No Check Engine Light)

15 DaimlerChrysler Truck Group High Idle Regeneration Procedures Aftertreatment System Depress Switch for 4 Seconds RPM will Increase to about 1200 Engine will bring up the Temperatures & Initiate Regenerating the Filter Approximately Minutes Later the Engine will Complete the Regeneration & the Engine will Return to 600 RPM Hot Exhaust Temp Indicator Lamp May Remain On Hot Exhaust Lamp is Information Only No Driver Action Required DPF Regeneration Switch High Exhaust Temperature Lamp

20 DaimlerChrysler Truck Group Idle Time Strategy – MBE 900 (9) Idle Scenario (Overnight): If the truck idles overnight, just before any of the regeneration indicator lamps light up, you have at least the amount of time – indicated by the dotted lines below – remaining, until the Aftertreatment System has to regenerate Idle Time/Hours Idle RPM >15 hrs >22 hrs

21 DaimlerChrysler Truck Group - Parked Regen Engine Speeds: MBE900 = 1200 rpm S60/HDEP Customer Demo = 1600 rpm MBE4000 = 1300 rpm (potential to vary) - To Cancel a Parked Regeneration hold the DPF Switch to the ON position for five (5) seconds and release. - A Parked Regeneration will stop if the key is turned to the off position, the truck is put into gear or the parking brake is released. - If a Parked Regeneration is canceled; the driver has 15 minutes to restart the process to have it pick up where it was interrupted. If the 15 minute timer has expired then the Parked Regeneration will start over from the beginning. - The High Exhaust System Temperature (HEST) Lamp will remain on until the exhaust temperature falls below 975F or the vehicle speed exceeds 5 mph. - Idle Shutdown Timer (if enabled) starts when Parked Regeneration is completed.
