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

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.

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

Biodiesel Use in Engines Lubricity
Mix with Ultra-Low Sulfur Diesel 1 % with No. 2 Diesel 2 % with No. 1 Diesel
804/20/23
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

Engine Warranties B5 Blends ASTM Standards
1004/20/23
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

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

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