  5. ACERT™ Technology

  6. JP-8 Fuel InCaterpillar Engines • Caterpillar Has Allowed The Use Of JP-8 Fuel • Catalytic Converter Reliability and Durability Concerns With High Sulfur Fuel

  7. JP-8 Fuel • Current JP-8 Fuel Specification (MIL-DTL-83133E) Allows Sulfur Levels Up To 3000 PPM • Sulfur Levels For Commercial On-Highway Fuel Is Currently Regulated at 500 PPM (15 PPM 2006) • Fuel Used For Certifying Engine Emissions Is Regulated By EPA (or EEC)

  8. Using JP-8 Fuel • 7 - 12% Reduced Power • Less Energy In A Gallon Of Fuel Means More Fuel For A Given Mission • Engines Will No Longer Be Emissions Compliant

  9. Aftertreatment Reliability • Over 80,000 in service • No service required Durability • Stainless steel construction • Low skin temperatures

  10. Catalyst Exhaust In Catalyst Substrate

  11. High Sulfur JP-8 AndCatalytic Converters • Caterpillar Has Not Tested The Durability Of Catalytic Converters With JP-8 Fuel • During Light Load Applications, Sulfur Deposits Will Form On The Catalyst Substrate • Sulfate Deposits Mix With Water, Sulfuric Acid Is Formed And Deteriorates The Exhaust System At An Accelerated Rate

  12. Options/Recommendations • Update JP-8 Fuel Specification To Match Up With Commercial Fuel Specifications • Run Durability Tests To Quantify The Degration Of The Catalytic Converter With JP-8
