A STUDY OF EMISSION & PERFORMANCE CHARACTERISTICS OF DIESEL ENGINE RUN BY DUAL FUEL (BIO DIESEL + ACETYLENE GAS)

This investigation targets on the effective production and utilization of vegetable seed biodiesel and their blends in a DI diesel engine. The investigations were carried out in single cylinder, water cooled DI diesel engine with eddy current dynamometer. In the first phase of this work, biodiesel produced from Prosopis Juliflora seed oil using conventional transesterification methods. Analysis and thermo-physical properties of biodiesel and their blends from both processes were analysed. Run the diesel engine using all the Prosopis Juliflora seed oil methyl esters and their blends to analyse the performance, emission and combustion characteristics. From the results, brake thermal efficiency (BTE), oxides of nitrogen emission (NOx) were slightly reduced and hydrocarbon (HC), carbon monoxide (CO) and smoke emission were increased while using the vegetable seed methyl esters and their blends. In this case 25% & 50% of Prosopis Juliflora seed biodiesel blend which is extracted from assisted transesterification process gives the comparable results to standard diesel fuel
