Utilization of fusel oil as a fuel for gasoline engine, a review

Abstract

The essential issues facing the world are climate change, global warning, energy price, and energy supply crisis. The main responsible for these problems is the petroleum based energy supplement. Carbon dioxide amount increased in environment and the need to higher energy through alternative fuels are becoming important. This should meet through the increase of the sources of renewable and clean energy with limited fuel supplies. Many researchers are studies alcohol as alternative fuels. Fusel oil is produced from fermentation process with higher alcohol content as a byproduct. In spark ignition engine, potential usage of fusel oil is took care as a renewable fuel during the last decades. In the present study, the objective is to survey the impacts of fusel oil-gasoline mixture on the performance (break torque, break power, brake specific fuel consumption, efficiency, & effective) and also characteristics of combustion and emissions (CO, HC hydrocarbons, NOx)) of SI engine. The conducted literature survey finding from this study reveal that torque, thermal efficiency, and engine power have slightly improved and specific fuel consumption increased when using fusel oil fuel. Emissions of CO & HC were increased with a reduction in the nitrogen oxide NOx and knocking. Accordingly, fusel oil may be used as a fuel with high efficiency in SI engine.
