Overview• Biodiesel is perfect substitute for normal

diesel.• Biodiesel is a fuel produced from vegetable

mass, animal fat and recycled oils.• Best green house gas mitigation strategy.• Biodiesel is widely produced from soybean

in United States.



Overview• Biodiesel is both environmental friendly

and is also a renewable source of energy.• Biodiesel can be used to operate any

vehicle or equipment which uses diesel as fuel with no or minimal modifications.

• Bio diesel is available in almost all the regions in United states.



Types of Biodiesel• There are 2 main categories: Neat and

blended biodiesel• B100 is 100 percent biodiesel.• Biodiesel blends are with a composition of

both biodiesel and conventional diesel.• B20- 20% biodiesel and 80% diesel• B5- 5% biodiesel and 95% diesel.



Characteristics• Biodiesel is less hazardous than common

salt i.e. hazel free handling.• It is less viscous than diesel and so greater

lubrication.• More corrosive .• Shorter shelf life.• Burns with very low toxic emission.• Contains no sulfur or aromatics.



Performance• Biodiesel shows similar fuel consumption,

horsepower, torque, and haulage rates as conventional diesel fuel.

• Biodiesel offers similar power to diesel fuel.

• Marked improvements of lubricity can be seen.

• Compatibility with existing diesel engine.



Performance• The usage of biodiesel provides almost

equal performance in terms of miles per gallon.

• The mileage improves in cold weather and there is no special care that is required in addition to care for normal diesel engines.



PerformanceEmissions compared to Diesel fuel


Emission type B100 B20

Total unburned HC -67% -20%

Carbon monoxide -48% -12%

Particulate matter -47% -12%

NOXS +10% -2% to +2%

Sulfates -100% -20%

PAH -80% -13%

Ozone Specific HC -50% -18%

Nitrated PAHs -90% -50%


Maintenance• At switch point be aware of compatibility and

check with owners manual .• Check for fuel filters on the vehicle frequently

and fuel system.• Cold weather can cause greater wax

deposition if neat biodiesel is used.• Regularly check the fuel hose and other

rubber materials.



Maintenance• Check for warranty statements• Care of painted surfaces.• Use the blends of B20 or higher within the

6 months of purchase.



Environmental benefits• The only alternative fuel to have

completed EPA requirements.• Biodiesel has lower levels of hazardous

emissions compared to conventional diesel.

• Substantial reduction in unburned hydrocarbons, carbon monoxide and particulate matter.



Environmental benefits• Biodiesel contains no sulfur or aromatics.• 78.5% reduction of CO2 emission.• Has a overall positive energy balance.• Best strategy to mitigate green house

effect.



Energy benefits• Utilizing domestic surplus of vegetable oils

will enhance energy security.• Decrease in foreign oil dependence while

creating jobs in United States.• Biodiesel being renewable source of

energy gives an opportunity to produce as much as required wile minimizing the harm to the environment.



Economic benefits• Increased utilization of renewable bio fuels

result in significant microeconomic benefits to both urban and rural sectors.

• Can create balance of trade.• The expenditure on securing foreign oil

($57 billion), foreign tax credits account to $4 billion, environmental costs are $45 per barrel.



Economic benefits (cont..)• For every billion dollars spent on foreign

oil result in 10,000-25,000 jobs lost in US.• By reducing dependence on foreign oil can

help conserve economy and preserve American jobs.

• The average price per bushel of soybean can go up by 17 cents annually by the continued growth in biodiesel usage.



Drawbacks• Higher retail prices.• Lower shelf life causes the storage time

restrictions.• Greater oxidizing and corrosive nature

leads to little excess maintenance cost.• Requires frequent change of fuel filters.• The manufacturer may void the warranty if

the cause of engine problems because of biodiesel.
