Experimental and theoretical Investigation of using bio diesel in Diesel engines

Abstract

newlineEver increasing consumption of fossil fuel and petroleum products newlinehas been a matter of great concern for India The huge out go of foreign newlineexchange on one hand and the increase in the price of crude oil on the other newlinehand have affected the development of India This has led to the increase in newlineinflation upto 11 91 as on July 2008 Apart from this pollution and related newlinehealth hazards global warming climatic change energy security depletion of newlinefossil fuel and problems related to transport and distribution of non renewable newlineconventional fuels have propelled alternative energy and related technologies newlineto the fore front of national agenda The consumption of diesel fuel is six newlinetimes higher than that of gasoline in India and even a few percentage of newlinesubstitution for diesel fuel will save a considerable amount of foreign newlineexchange India has high potential for producing liquid bio fuels like ethanol newlinemethanol bio diesel etc Bio diesel is considered to be a promising alternative newlineto fossil fuels world wide Because it is derived from renewable resources newline plants this can greatly improve energy security and prevents the shortage of newlineconventional fuel newlineIn this present work four different blend ratios of esters in varying newlineproportions viz 20 40 60 80 with diesel and pure esters bio diesel newlineare used for investigating performance combustion and emission newlinecharacteristics The esters and their blends were prepared in laboratory newline newline
