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

  3. Aftertreatment System Aftertreatment Regeneration Animation

  4. Aftertreatment System 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

  5. Aftertreatment System 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

  6. Aftertreatment System 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 4 - 8 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

  7. Aftertreatment System Regeneration StrategyVocational Applications Vocational Applications may require stationary or “Parked” regenerations under light-load conditions STATIONARY “PARKED” ACTIVE No Driver Effort Required PASSIVE

  8. The DPF Regeneration Cycle 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).

  9. The DPF Regeneration Cycle Bring vehicle to highway speeds to allow for an Automatic Regeneration OR Perform a Parked Regeneration. FILTER REGENERATION RECOMMENDED. 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.

  10. 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. 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.

  11. The DPF Regeneration Cycle Vehicle must be parked and a Parked Regeneration OR Service Regeneration must be performed. PARKED REGENERATION REQUIRED – ENGINE DERATE. + 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.

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

  13. Aftertreatment System High Idle Regeneration Procedures • 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 DPF Regeneration Lamp Light On Solid

  14. Aftertreatment System High Idle Regeneration Procedures • 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) DPF Regeneration Lamp Light Flashing

  15. Aftertreatment System High Idle Regeneration Procedures • Depress Switch for 4 Seconds • RPM will Increase to about 1200 • Engine will bring up the Temperatures & Initiate Regenerating the Filter • Approximately 20-40 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

  16. Exhaust Diluter Testing 415°F Reduction in Max Temp @ 6” Away from Pipe Stock Pipe Max Temp = 806°F / 430°C With Diluter Pipe Max Temp = 388°F / 198°C

  20. 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 RPM >15 hrs 800 6 3 61 36 10 6 >22 hrs 700 91 55 9 14 4 9 10 20 30 40 50 60 70 80 100 Idle Time/Hours

  21. Parked Regeneration Procedure (FAQ) - 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.

  22. DDEC Reports – Trip Activity Explanation 1/2 2 1

  23. DDEC Reports – Trip Activity Explanation 2/2 1 • Parked Regen Count: Count of Parked Regeneration attempts. • Driving Regen Count: Count of Over-the-road Regenerations. • Parked Regen Fuel: Dosing Fuel + Fuel to run the engine • Driving Regen Fuel: Dosing Fuel used during Over-the-road Regenerations. • Idle Fuel: The amount of fuel used while the engine was in Idle Mode. • Trip Fuel: Driving Fuel + Idle Fuel + Total Regen Fuel  Total Regen Fuel = Parked Regen Fuel + Driving Regen Fuel • Idle Time: Trip Time spent in Idle Mode. • Trip Time: Driving Time + Idle Time + Parked Regeneration Time • Parked Regen Time: Total time required for Parked Regeneration. 2

  24. DPF Maintenance Frequency Ash Cleaning Intervals are fixed in the engine calibration • Dependent on engine only • CJ- 4 oil • required on the MBE 900 • optional on MBE 4000 & Series 60 When mileage is reached the Check Engine lamp comes on.

  25. Aftertreatment System DPF Maintenance DDC Exchange Program • Utilizes a liquid cleaning solution to flush out ash from the filter cells • 95% Effective • Shorter Service time than air cleaning • No Parked Regen Required! Ash accumulation

  26. Aftertreatment System Liquid Cleaning • Filter is cleaned with a proprietary liquid solution only available with DDC filters • Most efficient method, 90-98% efficient • Process will be performed at DDC Remanufacturing Centers • Exchange program will be available • 45 minutes of labor time • $500 - $750 expected list price • A process only available with DDC filters
