Abstract: The study investigates the comparative performance of a single cylinder SI engine operated on treated and raw biogas. The methane content of this gas is utilised as the fuel. The biogas is treated with different methods before fuelling in the engine and hence the performance of the specified engine is compared. The raw biogas is treated for removal of moisture and H₂S because H₂S is poisonous in nature and moisture lowers the power output and may corrode engine parts. In this work, CaCl₂ and silica gel were used separately for the absorption of moisture. Activated carbon and iron chips were used for the elimination of H₂S. The results revealed that the increase in efficiency depends on the type of treatment given to raw biogas. Moreover, scrubbing of moisture had a greater impact as compare to the H₂S removal. Effect of biogas treatment on engine emissions is also studied.
