Effect of Fuel Oil - Gasoline Fusel Blends on the Performance and Emission Characteristics of Spark Ignition Engine: A Review

摘要

Alcohol-based as alternative fuels attract the attention of many researchers. Many kinds of research have been conducted on performance, combustion and emission characteristics of alcohol utilized in spark ignitionudengines. Fusel oil is an alcohol based fuel obtained as a by-product of alcohol fermentation from agricultural such asudbeet, cone, potatoes, rice, etc. The calorific value, higher evaporation heat and octane number of fuel oil close to other alternative fuels. Despite that, there is limited number of studies refer on the usage of fusel oil as fuel in spark ignition engines. This paper reviews the works done ‘effects of fusel oil as a fuel blends on performance (brake torque, brake power, BSFC, effective efficiency, EGT) and emissions (CO, NOx, HC) characteristics in spark ignition engine. It was seen that when fusel oil – gasoline blend used at almost the engine torque and specific fueludconsumption increased, Also HC and CO emissions averagely increased. Furthermore knocking and nitrogen oxidesudNOx were decreased .Moreover volumetric efficiency and octane number increases with the increase in percentageudof fusel oil in blend tests. In other hand the negative effects that happened in engine performance caused by theudhigher water content in fusel oil.
