Abstract

This paper presents the influences of ethanol addition to gasoline on bench test a spark ignition engine performances and emissions characteristics. The use of ethanol gasoline blended fuels decrease the brake power and brake torque, and increases the brake specific fuel consumption (BSFC). Ethanol gasoline blended fuels show lower brake torque and brake power and higher BSFC than gasoline. When ethanol containing oxygen is blended with gasoline, the combustion of the engine becomes better and therefore CO emission is reduced. HC emissions decrease to some extent as ethanol added to gasoline increase, as the percentage of ethanol in the blends increased, NOx emission was decreased under various engine speeds.
