Incras nvironmntal awarnss and dpltion of rsourcs ar driving industry to dvlop viabl altrnativ ful from rnwabl rsourcs that ar nvironmntally mor accptabl. Among th many altrnativ fuls biodisl ar considrd ar most dsirabl ful and vgtabl oil is potntial candidat. Th world is confrontd with th twin criss of ful dpltion and nvironmntal dgradation.

I. INTRODUCTION In rcnt yars convntional sourcs ar usd mostly but ths sourcs ar on day coms to nd bcaus of that w nd to discovr th altrnativ for convntion sourcs. iodisl is prfct option for convntional sourcs in which w can us iodisl in prcntag lik 1% 2% 4% 6% 8% & 1%.in th biodisl (Undi oil) usd hr for prformanc, using biodisl in disl ngin it s also controls on pollution bcaus incras in population and also bcaus of convntion sourcs incras in pollution also ffcts on human lif for minimizing biodisl dsir option using disl in prcntag. Enrgy is a major nd for th dvlopmnt of country and th incras in population nds mor nrgy for both conomic and social dvlopmnt awan ET. Al [1] th problm of using nat vgtabl oils in disl ngins rlats to thir high viscosity. Th high viscosity will lad to blockag of ful lins, filtrs, high nozzl valv opning prssurs and poor atomization. On hundrd prcnt vgtabl oils cannot b usd safly in DI disl ngins. Th problms of high ful viscosity can b ovrcom by using strs, blnding and hating. Vgtabl oils xhibit longr combustion duration with modrat rats of prssur ris, unlik ptrolum drivd fuls. Th us of vgtabl oils, such as palm, soya ban, sunflowr, panut, and oliv oil, as altrnativ fuls for disl is bing promotd in many countris. II. LITERATURE REVIEW Wagnr t al.

Thr was no diffrnc in thrmal fficincy rsulting from th us of th various fuls to powr th ngin. Th strs showd a slight powr loss and incrasd ful consumption, which was attributd to th lowr gross hating valus. Engin war was normal. Thr was, howvr, an incrasd carbon dposition on th pistons with th mthyl and butyl strs. Emissions of oxids of nitrogn wr significantly highr for th strs. Thy concludd that th str should b usd on a shorttrm basis, and that furthr tsting to b don for dtrmining long-trm str ful ffcts... C. Srinidhi at al. [2] prformd an xprimnt analysis of prformanc paramtr (such as brak powr, brak spcific ful consumption, brak thrmal fficincy and Exhaust Gas tmpratur) and mission charactristics (NOx, HC, CO. tc.) is obtaind for various bio disl and disl blnds and compard with ordinary disl at various loads on a modifid variabl comprssion ratio CI ngin. Th rsults of th invstigation shows that th prformanc and mission charactristics of th ngin fulld with Undi oil mthyl str disl blnds is comparabl to th ordinary disl. S.Sundarapandian and G.Dvaradjan [5] xprimntal work don and valuat th prformanc charactristics, combustion paramtrs and missions of vgtabl oil strs lik Jatropha, Mahua and Nm Oil strs. From th rsults, it is found that th hat rlas and work don ar rducd by about 4% for Jatropha, 5% for Mahua and 8% for Nm oil strs whn compard to disl. From th invstigation, it is concludd that th prformanc of vgtabl oil strs ar good. Thus th dvlopd modl is highly compatibl for simulation work with bio disl as an altrnativ ful. III. TEST SET-UP 1. Th supply mains of th control panl wr switchd ON. 2. Th mains gat valv was opnd and th pump was switchd on and th watr flow rat to th ngin cylindr jackt (3 lit/hr) and th calorimtr (5 lit/hr) wr st. 3. Engin was startd by hand cranking and allowd to run for about 2-25 min to stady stat conditions. 4. Th ngin had a comprssion ratio of 17.5 and a normal spd of 15 rpm controlld by th govrnor. Th ngin is first run with nat disl at loading conditions of %, 2%, 4%, 6%, 8%, and 1%. twn two loads trials, th ngin was allowd to rach stabl stady stat condition by running it for 3 min bfor talking th radings. At ach loading condition, prformanc paramtrs namly spd, xhaust gas tmpratur, brak powr and mission paramtrs NOX, CO, HC, C wr masurd undr stady stat conditions. With th abov xprimntal rsults, total ful consumption, brak spcific ful consumption, brak spcific nrgy consumption and brak thrmal fficincy wr calculatd. 5. Engin was thn run with blnds of Undi mixd with disl 2%, 4%, 6%, 8%, 1% by volum. Prformanc paramtrs and mission at ach loading conditions wr masurd. 6. Th whol st of xprimnts wr rpatd for comprssion ratio of 15,16,17,17.5 and 18. 7. Th abov dscribd xprimntal procdur was rpatd for Undi.

Emission of CO2, CO, HC is rducd as comprssion ratio changs and mainly th mission of NOx is slightly incrass. W ar using lnd 2% in that missions ar minimizs compar to th disl ful also mchanical fficincy is incrass. 6 blnds th mission of NOx is incrass du to high combustion tmpratur othrwis for blnds is proportionally incrass For blnd 1 rak Spcific ful consumption is minimum as compar to disl.
