Module 1Learning Objectives

• What is biodiesel?
• Why biodiesel as a vehicle fuel?
• Biodiesel performance characteristics

5
What is Biodiesel?

• General Definition
• Biodiesel (B100) is a domestic, renewable fuel
  for diesel engines derived from natural oils,
  such as soybean oil, that meets the
  specifications of American Society of Testing
  Materials (ASTM) D 6751.
• Additional Information
• Biodiesel (B100) can be blended in
  concentrations of up to 20 with petroleum-based
  diesel fuel and used in existing diesel engines
  with little or no modification. Biodiesel (B100)
  is not raw vegetable oil. Courtesy National
  Biodiesel Board

Little Known Fact

• Rudolph Diesel designed
• the diesel engine in 1894 torun on peanut oil
• The use of vegetable oils for
• engine fuels may seem
• insignificant today. But such
• oils may become in the
• course of time as important as
• petroleum and the coal tar
• products of the present time.

Why Biodiesel? - 2

• Biodiesel is non-toxic
• Biodiesel does not contaminate ground water or
  soil
• Most commonly used as B20
• 20 biodiesel 80 diesel blend
• Can be used in lower percentage blends (e.g., B5,
  B10)

9
Why Biodiesel? - 3

• Biodiesel (B100) is an EPAct Designated
  Alternative Fuel
• 450 gallons B100 1 vehicle credit
• Must be used in blends of at least 20 biodiesel
  to get credit
• Can be used to meet up to 50 of a fleets EPAct
  requirement
• Can not be banked or traded

10
Biodiesel Economics - 1

• Fleet fuel costs typically a penny a point or
  more over diesel
• New fueling station costs same as diesel
• Retrofit existing diesel station at minimal cost

11
Biodiesel Economics 2

• No vehicle price premium standard diesel
  vehicles
• Little or no vehicle modification necessary
• Many vehicles produced since 1994 are B20
  compatible
• Most manufacturers endorse B5 blends, higher
  blends use at own risk

12
Biodiesel Performance

• Startup, range, cold weather performance similar
  to petroleum diesel
• Fuel consumption, horsepower, torque, haulage
  rates similar to petroleum diesel

13
Biodiesel Performance - 2

• High Lubricity
• 2 biodiesel improves fuel lubricity by up to 66
• Protects, extends engine
• High Flash Point
• 260ºF vs. 125ºF diesel
• Safest fuel to use, handle, and store

14
Biodiesel Performance - 3

• Operates in conventional diesel engines and fuel
  injection equipment
• Cold Flow
• For B2-B20 use same precautions as 2 petroleum
  diesel
• No special storage required

  fuels
• Become familiar with biodiesel characteristics

17
Biodiesel Production - 1

• Refined from
• New vegetable oils
• U.S. Soybeans
• Europe Rapeseed (Canola) oil
• Yellow grease
• Recycled cooking oil

18
BiodieselProduction - 2

• Chemical process called transesterification
• Result Methyl esters and glycerin

19
Fuel Quality

• Standard for B100 is as a mixing fuel
• ASTM D6751
• Standard for B20 under development

20
Appearance Smell

• Transparent, usually yellow color
• Smell
• Fuel is odorless
• After burning, pleasing aroma, often smells like
  French fries

21
Compared to Other Fuels
22
Fuel Value

• Cetane
• Typical B20 50
• 2 diesel 40-45
• 1 diesel 48-52

23
Flammability

• Flash point
• B100 (soybean) 425 F
• B20 245 F
• Typical 2 diesel 160 F

24
Flammability - 2

• B20 flammability limits (by vol in air)
• Lower flammability limit 0.6
• Upper Flammability limit 7.5
• Diesel flammability limits
• Lower Flammability Limit - 0.3
• Upper Flammability Limit - 10
