Abstract
ABSTRACT Escalating energy requirements and concerns over the climate changes entail the researchers to find a viable alternate fuel. Energy derived from waste offers two advantages (i) it compensates the energy demand and (ii) reduces the pollution caused by dumped waste products. In the present study fleshing waste from tanneries is used as feedstock to produce biodiesel which was used as a fuel to partially replace fossil diesel. Three binary blends viz., D90WLB10, D80WLB20, and D70WLB30 were prepared using splash blending technique and utilized in a compression ignition engine to assess its influence on various characteristics of diesel engine. Results show that WLB blends presented lower PCP and higher HRR than baseline diesel fuel. The engine performance deteriorated with WLB blends against diesel operation. Among the blends, D90WLB10 showed 4% and 6% higher BTE than D80WLB20 and D70WLB30, respectively. Addition of 10% by vol of WLB to diesel increased the NOx emission, however, it suppressed as the proportion of WLB increases. D90WLB10 presented lower smoke, HC, and CO emission when compared to the other blends. The study revealed that D90WLB10 blend exhibit better engine performance with lower emissions and can be utilized in diesel engines without any engine modifications.
