Oil provides energy for 95% of transportation and the demand of transport fuel continues to
rise. According to the assessment of IPCC (International Panel on Climate Change) to climate
change, global oil demand will rise by 60% from 75 Mb/d in 2000 to 120 Mb/d in 2030. Almost
three quarter of the increase in demand will be form the transport sector. Oil will remain the
fuel of choice in road, sea and air transportation. Our country being a developing country, the
increase in demand in our country for oil for use in the transport sector will grow at a much
higher rate. All countries including India are grappling with the problem of meeting the ever
increasing demand of transport fuel with the constraints of international commitments, legal
requirements, environmental concerns, and limited resources. In this context transport fuels
of biological origin have drawn a great deal of attention during the last two decades. Biofuels
are renewable liquid fuels coming from biological raw materials and have been proved to be
good substitute for oil in the transportation sector. As such Biofuels ethanol and Biodiesel are
gaining world wide acceptance as a solution for problems of environmental degradation,
energy security, retracting imports, rural employment and agricultural economy.With a view
to add Bio-Fish Oil to the list of biodiesel, experimental studies were made using this bio oil in
a single cylinder diesel engine and generator set as substitute for diesel fuel and the results are
discussed. It is also blended with oxygenate and EGR technique also used to improve the
performance and reduce the emission of the engine. Encouraging results were obtained from
this investigation.Thepercentage reductionisCOe91%,CO2e62%,NOxe92%andCxHye90%
were attainedwhenthe enginewas runatmaximumloadusing BFOwith2%additive withEGR
and there was reduction in all the percentageswhen the engine was run in other loads also. In
the case ofNOx, therewasanincrease of thisemissionby about 48%in themaximumloadwith
BFOwhen compared with diesel, for obvious reasons and thatwas also reduced because of the
addition of oxygenates and EGR technique. The optimum values were obtained with 2% of
additive.When this percentage is increased or decreased the emission were increased
