摘要：Alternative fuels have become very important nowadays and proving their importance in both positive ignition engines and compression ignition engines, so as to reduce the consumption of gasoline and diesel respectively. Also, blending of these alternative fuels (additives) into gasoline has been proved important in improving various performance parameters and reducing emission parameters. Various studies have been carried out in the field of using additives in gasoline to see the effects on performance parameters like Brake power, Brake thermal efficiency, Volumetric efficiency and brake specific fuel consumption. Also, this study emphasizes reducing the emissions to the ambient. The aim of this review is to compare and study various additives which can be blended with gasoline and study their effect on performance and emission characteristics of Spark ignition engines.
