demand of automobiles is more due to population growth has result in great
demand for petroleum products. With crude oil reserves estimated to last for
few decades, there have been many researcher find alternate fuels. The depletion of
crude oil could reason a primary effect on the transportation sector. Biodiesel
is a clean burning alternative biofuel, which is produced from Sunflower,
karanja, jatropha, waste cooking oil, thumba, soybeans, animal fats, alge etc.
These are domestic and renewable source. The extracted crude oil cannot be used
as a directly in diesel engine because it has a high viscosity; due to high
viscosity of pure vegetable oils it will be responsible for high engine
deposits and lubricating oil thickening. That would reduce the fuel atomization
and increase fuel spray penetration. To create a biodiesel blend it can be
blended with conventional diesel. Biodiesel is manufacture from a chemical
process which is known as transesterification. Biofuels are mono alkyl esters
of long chain fatty acid derived from renewable biological sources. Biofules can
be directly used in the compression ignition engine without modify of existing
engine. Biodiesel fuel is a clean burning resource and it is the future of the

have no contained sulfur, aromatic, hydrocarbons, and particulate matter.
Much research work has
been done how to use vegetable oil both in its pure form and blended form. Many
project have been shown that the usage of vegetable oils in pure form is
possible but not preferable with the advent of the industrial revolution, the
use of energy in the form of fossil fuels began, this occurred in stages, from
the exploration of coal deposits to the exploitation of oil and natural gas
but, how long can we depend on this declining fossil fuels to run our car
engine, to light our kitchen stove. The secondary viscosity of vegetable oils
and the low instability influences those atomization Furthermore spread example
for fuel, prompting inadequate burning What’s more extreme carbon deposits,
injector gagging What’s more piston ring staying. Those routines utilized to
decrease viscosity need aid mixing for diesel, emulsification, pyrolysis,
oil can be effectively replacing diesel fuel. Application of diesel oil is in
the transport sector, agriculture form and industries for generating
electricity, running pumps and tractors. The entire use of diesel oil can be
substituted with vegetable oil. The properties of sunflower oil very close
together diesel. The sunflower oil can also be converted to bio-diesel and used
in automobile sector.
various advantages of using sunflower oil:
(1) The cost of 1 liter sunflower oil is
approx. Rs. 80/- hence it is approx. same price of diesel.
(2) Sunflower oil as fuels can provide
good lubrication to the engine.
(3) No toxic gases emission, no
greenhouse gas emission.
(4) Sunflower seeds can be grown in waste lands
and other lands with low nutritional content. The plant is also a nitrogen
dependence on sunflower oil would generate employment in rural areas.
are fossil fuel substitutes that can be made from a range of agricultural crops
and other sources of biomass. Any hydrocarbon fuel that is produced from
organic matter (living or once living material) in a short period of time –
days, weeks, or even months, is considered as biofuel. They are considered as
an alternative source of energy Importance:
Energy security – increasing oil prices,
need for alternative source of energy
To decrease greenhouse gas emission
To promote rural development
