This work concerns a systematic study of IC engine operation with 100% biogas as fuel (as opposed to the dual-fuel mode) with particular emphasis on operational issues and the quest for high efficiency strategies. As a first step, In Biogas CO2 does not help in combustion process but reduce the calorific value of biogas. H2S is in minor quantity but it has corrosive action on combustion chamber and also reduces calorific value of biogas. Also traces of moisture are to be removing for better thermal efficiency. So harmful gradients are removed and use only methane as a fuel. Subsequently, the model of KINETIC GF is used to predict effect of different parameters such as compression ratio, spark timing and combustion durations on engine performance and efficiency. The results show very high overall efficiencies with the manifold injection strategy. The main reasons are the higher volumetric efficiency and overall lean operation of the engine across the entire load range. Predictions show excellent agreement with measurements, enabling the model to be used as a tool for further study. Simulations suggest that a higher compression ratio (up to 13) and appropriate spark advance can lead to higher engine power output and efficiency. ]]>
