Effect of EGR on performance and emission of CI engine using biodiesel blend of pork lard

Need to search for renewable options as far as energy need concerns are imminent. This study is focused on investigation of CI engine using biodiesel made from the animal fat oil. In this study, process of transesterification is used to fabricate biodiesel from pork lard oil. B20 blend of the pork lard oil biodiesel is being checked for its engine performance and emissions. The effect of Exhaust Gas Recirculation on the performance & emission characteristics of a C.I. engine operated with this fuel is examined. Results indicate use of B20 blend biodiesel as substitution of pure diesel fuel is effective without modification of engine. Upon testing the results proved that the NOx emission of the engine is high for biodiesel fuel but it can be reduced by applying EGR. The NOx emission reduced considerably on increasing the EGR percentage but higher Hydro-Carbons and Carbon Monoxide emissions are noted on at higher EGR rates using biodiesel in engine emission test EGR rates between 5%-10% are optimum for emission control characteristics for the engine. However, the performance is slightly reduced on higher application of percentage of EGR. 10% EGR shows optimum performance on the engine. On the outset, this experimental investigation states that the B20 blend of Pork lard oil biodiesel is a suitable alternative fuel in C.I. engine with 10% of EGR for efficient performance and emission results.
