The present work is going to investigate the performance and emission analysis of crude animal fat and palm oil
(Bio-Dual fuel) as an alternate fuel for diesel engines. By using the trans-esterification process Crude oil is converted to
methyl esters. The Animal fat & Palm oil With Diesel (APD) is taken into 5 blends they are APD10 (10% of Animal fat and
palm oil with 90% Diesel), APD20, APD30 APD40 and APD50 then found out the performance and emissions of all blends
and it compares with the pure diesel. The blend APD20 is improved the mechanical efficiency and Brake thermal efficiency by
3.93% and 3.71 % of respectively at full load when compare to the pure diesel and reduce the absorption coefficient (K) and
smoke density by 83.09% and 68.52% respectively. Based on the performance and emissions results APD20 is selected as an
optimum blend. For improve combustion process and reduces the emissions Iso Propyl Alcohol (Ignition improved) was added
by the 1%, 2% and 3% volume ratios of APD20. The blend APD20 with added ignition improver 10ml showed an increase in
brake thermal efficiency.
