Influence of Alcohol Addition in Pyrolytic Oil To Upgrade its Properties : A Fuel to Ci Engine

This work aims to up gradation of pyrolytic oil, produced from Delonix Regia Pod (DRP) through batch type pyrolysis process. During the process the yield rate of pyrolytic oil yield is maximum at 450°C and above 450°C, the yield rate of syngas increases than pyrolytic oil. Though the pyrolytic oil has higher viscosity and heavier molecular components leads to incomplete combustion, which causes lower efficiency and higher emissions. Recently researchers were focus on the up gradation of pyrolytic oil. Among the various process addition of supercritical fluids to the pyrolytic oil, leads to the improvement in their fuel properties. In this research work both ethanol and methanol is added 80% respectively to pyrolytic oil, which leads to the formation of E80P20 and M80P20 blends. Further M80P20 shows better fuel properties than E80P20. The major properties like viscosity, heating value are 15cSt, 40.25MJ/kg and significantly improved than E80P20 blend. The performance and emission characteristics of CI were carried out by both the blends along with the base as diesel fuel. The BTE of M80P20 has increased 2% than E80P20 blend and also other emission like NO x , CO and HC were considerably reduced in M80P20 than E80P20. Based on the investigations both blends will can be used in the CI engine without any modifications
