Abstract
Nowadays, biofuels have become primary important in the automobile and transport sector as an alternative to current conventional fuels. It is well known that the major varieties of vegetables are edible while few of them are deployed for research purposes such as palm oil which is non-edible oil. Palm biodiesel was extracted from raw Palm Kernel Oil by the application of Esterification and Transesterification. Palm biodiesel was blended with conventional diesel. Present work touches upon working of conventional diesel engine and exhaust emission with diesel, palm biodiesel and also blends of palm diesel and diesel blends. Apportioned fuel combination of diesel and palm biodiesel are P0: 0% Palm Kernel Oil + 100% diesel, P20: 20% Palm Kernel Oil + 80% diesel, P40: 40% Palm Kernel Oil + 60% diesel, P60: 60% Palm Kernel Oil + 40% diesel and P100: 100% Palm Kernel Oil + 0% diesel. The experimentation was carried out with no alterations to the design of the test diesel engine. In the current work, working of the Engine and engine exhaust were examined at compression ratio 18:1. Experimentation was carried out at various loads besides variable blends and results were presented. Experimentation was carried out at 1500 rpm and maximum load at compression ratio 18:1. The influence due to change in the blend ratios on the brake thermal efficiency, brake-specific fuel consumption and emission analysis was also examined. Performance evaluation covers evaluation of brake power (BP), brake SFC, brake thermal efficiency, etc. Emission testing covers CO%, CO2% NOx (ppm) emissions as measurements done by gas analyzer. The experimentation reveals that the BTE of palm biofuel engine is 29.01%, which is more than that of diesel, while the BSFC of 0.293 kg/kWh is less than that of the diesel. In the part of emission analysis, NOx, CO% and CO2% were 153 ppm, 0.006% and 2.09%, respectively at maximum BP for palm biodiesel and tallied with diesel as better substitute.
