  2. Retrofit – What’s Not To Like

  3. Legacy Fleet Retrofits – More Than Aftertreatment • Repowers • Rebuilds • Replacement • Refuel • Retrofit aftertreatment

  4. Opportunity

  5. Retrofit To First Fit

  6. The Business Case for Aftertreatment

  7. Leveraging OEM Technology • Aftertreatment devices • 2 million aftertreatment devices shipped • Every on-road engine in U.S. and Europe is now shipped with an aftertreatment device

  8. PM Control Devices

  9. Diesel Oxidation Catalysts • PM ≥ 20% • CO ≥ 90% • HC ≥ 90%

  10. Partial Filters • PM ≥ 50% • HC ≥ 90% • CO ≥ 90%

  11. Passive Regeneration Filter (Catalyzed) • PM ≥ 85% • CO ≥ 90% • HC ≥ 90%

  12. Active Electric or Fuel Regenerated Filter • PM ≥ 85%

  13. Cummins Filtration Coalescing Crankcase Ventilation System • Removes emissions from open crankcase systems • Also helps reduce drips and oil consumption • Crankcase Breather > CCV filter > Air Intake/Drain • Change Filter every 25,000 miles • Conditionally Verified with CES Diesel Oxidation Catalyst

  14. PM and NOx Control Devices

  15. Passive Filter with Lean NOx Catalyst • NOx ≥ 25% • PM ≥ 85% • CO ≥ 90% • HC ≥ 60%

  16. Selective Catalytic Reduction (SCR) NOx reduction 60-90%, CO ≥ 40%, HC ≥ 40%

  17. Selective Catalytic Reduction (SCR) with a DOC or Filter • NOx reduction 60-90%, 25-85% PM reduction • HC ≥ 90%, CO ≥ 90%,

  18. U.S. Installations

  19. Recent CES projects in Region 4 • Santee Cooper Settlement • Retrofitted 105 South Carolina Dept. of Education School buses using CCRT • Charlotte Area Transit • Retrofit 76 transit buses with DPF technology • Sarasota County Area Transit • Donated 1 retrofit DPF for transit bus • North Carolina, South Carolina School buses • Several projects retrofitting school buses with DOC technology

  20. Retrofit Success

  21. Retrofit – The time is right
