Enhancing gasoline fuel chararcteristics and engine operation criteria using octan boosters

The increase of energy demand and environmental contaminations hearten the utilization of alcohol-based as a alternatives fuels in spark ignition (SI) engine. The fusel oil is a byproduct developed from a fermentation process with higher alcohol content. It has high-octane and slight exhaust emissions, there for it takes important place between the substitutes fuels. During this study, effect of used mixtures of pure low octane gasoline & fusel oil on engine exhaust emissions & performance have been estimated after water removal from fusel oil. A single-cylinder, four-stroke SI engine has been used in this tests. The inspections execute at different speeds. The test fuels mixed by fusel oil at ratio of 5%, 10%, 20%, and 30%. In each speed, the engine’s performance & emissions size have been conducted. During the investigations, it have been observed that the brake power (BP) and specified fuel consuming (SFC) rises as the size of fusel oil risen in the mixture.
