Performance of SI engine fuelled with producer gas at various spark timings and compression ratios-A review

Abstract

Energy is important in causing the economic growth of any country. Due to depletion of conventional energy sources and escalating prices of such fuels, the researchers have started to focus their attention on the use of alternative fuels. A possible solution may be found with renewable energy sources such as biomass, solar, hydropower and wind energy. Biomass is abundant, environmental friendly and is an attractive substitute to fossil fuels. When compared to all energy sources from biomass, alternative fuels in gaseous form offer more convenience. Producer gas from biomass gasification can be used as an alternative fuel in spark-ignition engines. Use of 100% producer gas in spark ignited engine is peculiar because of its low energy density, hence low output and efficiency. This paper reviews the use of producer gas as alternative fuel for SI engines, experimental investigation on producer gas as fuel, merits, demerits and problems faced.
