Abstract: In resent year, increased environmental awareness and energy shortages have encouraged researchers to investigate the possibility of using alternate fuels. The purpose of finding the alternate sources is to minimize the consumption of conventional fossil fuels and in turn to reduce the degradation of environmental quality to a great extent. The use of bio-based fuels like biogas produced from biomass and bio-wastes is a valuable energy source which is sustainable that can be manufactured from locally available waste streams thereby solving the local waste problem. Local wastes (organic wastes) contain enough energy to contribute significantly to energy supply especially the rural regions of developing countries. Biogas is a clean and environment friendly fuel produced from anaerobic digestion of agro, animal or human wastes. The biogas has about 60 % methane and 40 % carbon dioxide with small traces of H2S. The use of H2S leads to formation of SO2 which combines with the water vapor to form acids and hence corrode the metals. Thus, raw biogas as such cannot be used for powering vehicular I.C engine. In the present work, an attempt has been made to upgrade the quality of raw biogas by removing CO2 and H2S, thus enriching its methane content up to the natural gas level and to study the performance of four stroke S.I engine aspirating upgraded biogas as primary fuel and its emission characteristics.
