Abstract:

         Rising petroleum prices, increasing threat to the environment from exhaust emissions and global warming have generated an intense international interest in developing alternative non-petroleum fuels for engines. Ethanol has been identified as one of the possible alternative fuels. Besides being a biomass based renewable fuel ethanol has cleaner burning and higher octane rating than the various vegetable oils. India is depending on foreign oil and investing more money for importing the same. It will be reduced by making an ethanol production plant in and around India. It leads to enhance agriculture – backbone of our country ( by means of producing vegetable oils for manufacturing ethanol) and improves economy of India and increases employment opportunities. Ethanol burns more completely and at slightly cooler temperature than normal gasoline. This means longer spark plug life and fewer engine deposits, keeping the existing fuel system clean. Ethanol burns more completely which results in fewer tail pipe emissions as much as 30% less CO, 12% lower volatile compounds, 30% fewer toxic compounds, 3% fewer NO. Vehicles which run on E90 are called “FLEXIBLE FUEL VEHICLE” (FFV). The main objective of our project is to convert existing single cylinder petrol engine (Bullet engine 350cc) into ethanol fueled vehicle. We have also conducted and compared performance tests of petrol with ethanol fuels (E75 and E90).
