Experimental analysis of biofuel produced from fat derivatives of bird and animal as an additive fuel in CI engine

Abstract

In the present work, an alternative form of biofuel for the Compression Ignition (CI) Engine is generated from inedible disposable chicken skin and animal fat. Further, they are experimentally investigated for different blends in the CI engine. The derived biofuel from chicken skin and animal fat is blended with diesel at different proportions at the rate of 10%, 20%, and 30% by volume. The blended fuel properties like Flashpoint, Fire point, Density, Kinematic Viscosity (KV), Heating value, and carbon content are experimentally determined and it is observed that they are reasonably close to the properties of diesel. The blended fuel is tested for performance and pollution parameters using a CI engine test rig. The results obtained are compared with diesel fuel for the same test conditions. The efficiency was observed to decrease which is due to lower Heating values of the blend, necessitating more fuel for the same power. Reductions in NOx and HC tailpipe emissions is an encouraging observation. B20 blend bio-diesel was found optimum as compared to other ratios of the blend. This paper emphasizes on the procedure for extracting fat from chicken skin and animal waste and then convert to biofuel. The findings from the work vindicate that the derived biofuel could be used in combination with diesel fuel for the effective partial replacement of diesel fuel in CI engines without any major alterations.
