Abstract


Bio-fuel application in diesel engines have now become popular from the point of view of fuel economy and emission reduction. In this experimental investigation, full fledge attempts have been made to prepare a Bio-fuel through transesterification from raw Neem oil. The derived fuel called “NEEM OIL METHYL ESTER” (NOME- C17H34COOCH3) has been used in a single cylinder water cooled diesel engine and operated with typical operating conditions. C17H34COOCH3 is the chemical formula of Neem Oil Methyl Ester (NOME) and the same is derived from the raw Neem oil through transesterification. The parameters of Neem Oil Methyl Ester, such as Balanced chemical equation of NOME, Percentage of Carbon, Hydrogen and Oxygen by weight or mass basis, Air/Fuel ratio of NOME by mass, Air/Fuel ratio of NOME by mass based on properties of test fuel, Air/Fuel ratio by mole basis, Oxygen requirement per kg of fuel for complete combustion, NOME by mass based on Properties of Test fuel, Higher calorific value of NOME, Lower calorific value of NOME, moles and molecular weight of reactant and product side, Total mass of carbon in one kg of flue gas, mass of flue gases formed per kg of fuel (mg), mass of air supplied per kg of fuel(ma), Excess air supplied, Percentage of excess air supplied were calculated for combustion. The Adiabatic flame temperature is also calculated both manually as well as programmatically with flowchart through C++ program. The above details calculated will be useful when the experimental investigation are carried out to validate the theoretical study
