Performance and Study of SI Engine using Ethnol Blended Gasoline Fuel

Due to growing energy needs and environmental concern worldwide have forced the interest for quest and consumption of renewable and environmental fuels .There are some other alternatives that can be accessible in engines with the possibility of reducing injurious gas radiations. Here we have considered gasoline as reference which is to be blended with ethanol. Then the Physical properties of the fuel are determined. SI engine runs on several speeds and part load which connected to dynamometer, in this mixture blend is containing 10%, 20%, and 30% ethanol and performance characteristics are assessed. In this paper it is shown that the ethanol blends can replace gasoline in SI engine, outcomes show that there is escalation in Brake power, Specific Fuel Consumption and Brake thermal efficiency on blending. The Result shows that using 20% ethanol blend is more effective and we can utilize it for further use in SI engines with little constraint on material used to sustain little increase in pressure.
