Abstract :

The present energy crisis caused by continuous depletion of scarce fossil fuels has resulted into global price hike of crude petroleum and is bound to affect the economy of many countries. Apparently vegetable oils have been gaining worldwide attention as an alternative energy source because they are environment friendly renewable in nature. Moreover, it operates well in a conventional diesel engine with very few or no engine modifications and can also be blended with diesel while still achieving substantial reductions in emissions. In the present work the performance, emission and combustion characteristics of twin cylinder direct injection diesel engine using diesel and bio-diesel were studied at different load conditions and different injection timings. The engine run on diesel and two different bio-diesel by various blend ratios of B20, B40, B60, B80 of MEOJ (methyl ester of jatropha ), MEON (methyl ester of neem oil) and B100 at 1500 rpm. This paper presents the results obtained the measurements of NOx and smoke density at different speed and load conditions for the two different bio-diesel and their blends with diesel. A combustion analysis was performed where heat release rate and maximum cylinder pressure were examined.
