Performance & emission of Si enginewith oxygenated fuel

Increased environmental awareness and quick depletion of natural resources are driving the researchers to develop viable alternative fuels from renewable resources that are environmentally more acceptable. The use of oxygenates to replace the lead additives in gasoline are being considered as an alternative. In this work, oxygenated fuel is prepared by mixing 80% of gasoline with 10%, 5% and 5% (composition I) and mixing 80% of gasoline with 15%, 2.5% and 2.5% (composition II) on volume basis of additives like Ethanol, Isopropyl alcohol, and Diethyl ether respectively. The study offers a comparison between the oxygenated fuel and gasoline in terms of engine performance and emission characteristics under varying load conditions. Experimental results of oxygenated blends of different composition show that the use of oxygenated fuels, without compromising the performance, the engine emission reduces to a higher extent.
