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

JP-8 Fuel 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)

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

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

High Sulfur JP-8 And Catalytic Converters High Sulfur JP-8 And Catalytic 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

Options/Recommendations 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
