Effects of waste chicken fat derived biodiesel on the performance and emission characteristics of a compression ignition engine

ABSTRACT

In this investigation, chicken fat methyl ester (CFME) was produced from the waste chicken fat obtained from meat processing industries. Blends were prepared with diesel-CFME, such as DCFME10, DCFME20, DCFME30, and DCFME40. The blends were tested in a direct injection diesel engine to examine the performance and emission characteristics. The results showed that the diesel substitution was attainable with CFME. DCFME30 had excellent performance and emission than other blends, but it was marginally lower than diesel. For the DCFME operation, brake-specific fuel consumption was higher and brake thermal efficiency was lower in comparison with diesel throughout the load spectrum. The CO (carbon monoxide), HC (hydrocarbon), and smoke emissions were reported to be lower for DCFME blends than that of diesel, but the NO (nitric oxide) emission was marginally higher throughout the load spectrum. A maximum of 30% diesel saving was obtained by using CFME, energy from animal residue.
