  1. Biodiesel Use in Engines John Nowatzki Extension Ag Machine Systems Specialist North Dakota State University

  2. Biodiesel Use in Engines • Use in Engines • Cold Weather Issues • Warranties • Emissions • Storage

  3. Biodiesel Fuel Characteristics

  4. Biodiesel Use in Engines • Petroleum diesel 140,000 Btu/gallon • Biodiesel 130,000 Btu/gallon • 1.1 Gallons of Biodiesel to do Same Work

  5. Biodiesel Use in Engines • Viscosity (Thickness) • Water - 1 cP (centipoise) • Summer Blend Diesel - 3 cP • Biodiesel - 5 cP • Crude Vegetable Oil – 40 cP • Poor Atomization • Deposits - Piston Rings, Valves and Injectors.

  6. Biodiesel Use in Engines • Solvency • Removes Deposits in Fuel System • Plug Fuel Filters • Deposits to Accumulate in Fuel Tanks

  7. Biodiesel Use in Engines • Lubricity • Mix with Ultra-Low Sulfur Diesel • 1 % with No. 2 Diesel • 2 % with No. 1 Diesel

  8. Cold Weather Issues • Cold Filter Plugging Point (CFPP) • Cloud Point • Soybean Biodiesel ~ +30° F • No. 1 Diesel ~ -35° F • When Biodiesel Nears the Cloud Point: • Anti-gel Additives or No. 1 Diesel • Fuel-Line or In-Tank Heaters • Insulate Fuel Lines and Filters • Store Equipment in Heated Buildings

  9. Engine Warranties • B5 Blends • ASTM Standards

  10. Engine Emissions • Generally Fewer Harmful Emissions • Hydrocarbon - 67 percent less • Particulate Matter and Carbon Monoxide • 48 percent less • Nitrogen Oxide – 10 percent more • Carbon Dioxide – 60 percent Less

  11. Storing Biodiesel • 6-12 Months • Cold Storage – Big Problem! • High Solvency – Loosens Tank Deposits • Prevent Water Contamination • Store in Dark Conditions • Analyze if Stored for Longer Period

  12. Summary • Excellent Fuel for Diesel Engines • 8 % Less Energy • Fewer Harmful Emissions • Higher Viscosity • Some Solvency Problems • Good Lubricating Qualities • Serious Cold Weather Issues
