2. Biodiesel is the name given to clean burning alternative fuel
produced from domestic renewable resources. The main commodity
sources for biodiesel in India is non-edible oils obtained from plant
species such as Jatropha Curcas (Ratanjyot), Pongamia Pinnata
(Karanj), Calophyllum inophyllum (Nagchampa), Hevca brasiliensis
(Rubber) etc.
According to ASTM standards Biodiesel is technically defined
as ,”the mono alkyl esters of long chain fatty acids derived from
renewable liquid feedstock, such as vegetable fats and animal oils ,for
use in compression ignition (CI) engines”.

3. 1. To examine the potential of waste cooking oil (WCO) for
their suitability as feed stock for biodiesel preparation.
2. To compare the fuel properties of the methyl esters of
WCO (WCO-biodiesel) with those of esters of fresh oil
and base line diesel fuel and also to investigate the
emissions and performance of a diesel engine running on
above biodiesels.

4. Biodiesel is produced by the transesterification of long
chain fatty acids derived from vegetable oils and animal fats
(triglycerides) with aliphatic alcohols (methanol or ethanol)
in presence of an appropriate catalyst to form esters of long
chain fatty acid (biodiesel) and glycerol (glycerin).
Biodiesel refers to a vegetable oil- or animal fat-
based diesel fuel consisting of long-chain alkyl (methyl,
ethyl , or propyl) esters.

6. Transesterification of a vegetable oil was
conducted as early as 1853 by Patrick Duffy, many
years before the first diesel engine became functional.
Rudolf Diesel’s prime model, a single 10 ft (3 m) iron
cylinder with a flywheel at its base, ran on its own
power for the first time in Augsburg, Germany, on 10
August 1893 running on nothing but peanut oil. In
remembrance of this event, 10 August has been
declared “International Biodiesel Day".

8. 1. Biodiesel has better lubricating properties and much
higher centane ratings than today's lower sulfur diesel
fuels.
2. Biodiesel addition reduces fuel system wear, and in
low levels in high pressure systems increases the life of
the fuel injection equipment that relies on the fuel for
its lubrication.

9.  Biodiesel can be used in pure form (B100) or may be blended with petroleum
diesel at any concentration in most injection pump diesel engines.
 New extreme high-pressure (29,000 psi) common rail engines have strict
factory limits of B5 or B20, depending on manufacturer.
 Biodiesel has different solvent properties than petrodiesel, and will degrade
natural rubber gaskets and hoses in vehicles (mostly vehicles manufactured
before 1992), although these tend to wear out naturally and most likely will
have already been replaced with FKM, which is nonreactive to biodiesel.
 Biodiesel has been known to break down deposits of residue in the fuel lines
where petrodiesel has been used.

10. It is natural, renewable and dissolved in water faster
then sugar.
It contains 11% Oxygen by weight and contains no
sulphur.
It takes black smoke from the back of a vehicle and
makes the exhaust smell faintly of popcorn!
It is lower toxic emission and particulate matter.
It is safe to store and has high flash point

11. 1) A vehicle cannot run on WVO alone; it must
start and stop on diesel because the engine has
to be warmed up and the oil must be heated
before use.
2) The whole cost of Bio-diesel is typically higher
than diesel fuel.

12. Methanol storage containers must be metal,
grounded, use masonry supports and must not
spill contents if connectors burn through.
Space required around tanks for firefighting
access.
Explosion proof electrical wiring.

13. 1. Biodiesels (Methyl Esters) is a diesel replacement waste
fuel made from virgin vegetable oils such as Soyabean or
Rapseed. It can also be made from recycled restaurant oils.
2. It is all natural, renewable & dissolves in water faster then
sugar.
3. It is 11% Oxygen by weight and contains no sulphur.
4. Biodiesel is safe to store and has a high flash point.
5. Biodiesel has greater Cetane from (50-56%) and lubricity
than diesel fuel, infact, 1% biodiesel increases lubricity by
upto 30%.
