Abstract
The excessive use of fossil fuels will certainly lead to the energy crisis and unsustainable condition of the environment in future. In this paper, the performance characteristics have been studied experimentally for a spark ignition engine running with different gasoline-alcohol (ethanol and methanol) blends as alternative fuels. It is observed that the brake thermal efficiency increases by more than 6% with 40% addition of ethanol or methanol to gasoline. Volumetric efficiency also increases due to alcohol addition to gasoline. Brake specific fuel consumption increases approximately by 20% with 30% alcohol addition. The maximum exhaust gas temperature decreases by 14% with methanol and 10% with ethanol for a blending of 40% alcohol with gasoline by volume.
