Demand for fuel and the use of petroleum products are being increased gradually which causes serious problems such as petroleum depletion, energy crisis and environment degradation etc. Consequently, at this juncture, biodiesel is found to beagoodalternativeandapromisingconventionaldieselfuel.Subsequently,theapplicationofbiodieselnotonlyfulfilling thegapofenergycatastrophebut,alsoprofferssomeshortcomingssuchashighoxidesofnitrogen,highfuelconsumption and higher density. Therefore, in order to prevail over this problems and reducing exhaust emission, the study has been undertaken to demonstrate the study on Emission Characteristics of a CI Engine fuelled with Wastes Chicken Fat Biodiesel(WCFB)blendswithExhaustGasRecirculation(EGR).Inthestudy,initially,BiodieselisobtainedfromChicken fatoilasaresult oftransesterificationprocess.Theexperiment workwasdoneonaCI-Engineusingabiodiesel(trialwith variable blends) achieved by Chicken fat oil with Exhaust Gas Recirculation (@30%).Further, the performance and emissioncharacteristicsofalltheblendswerecarried-outandwerecompareddecisivelywithpetro-diesel.Theexperimental results shows that, the enhanced Performance and Emission characteristics with B20 biodiesel blend and the momentous reduction in NOX emission using Exhaust Gas Recirculation approach was observed. In addition, the thermal efficiency was increased and SFC (Specific fuel consumption) was found to be better in blending fraction of WCF Biodiesel. A noticeable approach on the parameters like, decrease in carbon monoxide reduced unburned hydrocarbon(UBHC) and decreases in nitrogen oxide emissions are attained at the blending fraction of B20 biodiesel when compared with petro-diesel. Hence, there is a significant reduction in CO, UBHC and NOx emission parameters at B20 biodiesel blending ratio coupled with Exhaust Gas Recirculation (EGR) system. However, the EGR level was optimized (30%) with respect to the performance of CI Engine linking with significant reduction in the emission of NOX, minimum possible smoke, CO, HC emissions and corresponding with brakethermalefficiency.
