Biogas use as fuel in spark ignition engines

摘要: These This paper reviews the utilization of biogas in spark ignition engines with a view to making case for it as an efficient substitute fuel petrol. However, its gaseous nature which accounts low volumetric density implies that apart from basic modification needed accommodate fuel, engine might need further alterations get best this relatively cost and readily available fuel. Various modes enhancing performance particularly methane enrichment, prechamber combustion, alteration parameters, increasing compression ratio addition hydrogen improve emissions were drawn previous works validate efficiency viable SI engines.
