Abstract

Ethanol offers a near - term alternative to replace petrolium based fuels for spark ingition engines. It can contribute a considerable part of energy resources using domestic renewable resources.
This work comprises a comparative study for the performance and emission characterestics of spark ignition engines using gasoline and ethanol. The experiments were carried out on a four stroke four cylinders petrol engine modified to use ethanol as fuel.
The results show that ethanol can provide a smooth and clean burning fuel for convensional spark ignition engines if some little carburettor modifications are made and the problem of cold starting is solved.
The results also showed that ethanol has better detonation resistance which allows the use of higher compress ion ratios. Use of ethanol as a fuel for S.I.E resulted in increase of the engine power, lower emissions of unburned hydrocarbons and carbon monoxide.
