Performance and Emission evaluation of Butanol blends in SI Engine

In recent times, butanol emerges as one of the most promising option to diminish the prolong use of fossil products. The testing of different blends and composition of butanol with gasoline is newest theme of research. In the present work, three different fuels are prepared by using 5%, 10% and 15% blends of butanol with gasoline. The important performance parameters & emission characteristics of a conventional SI engine namely, brake power, torque, brake specific fuel consumption, fuel power, brake specific energy consumption, brake mean effective pressure, un-burnt HC emissions, CO emissions, NOx emissions, and CO2 emissions are tested. Result shows that the butanol blend of 15% is the most appropriate to use as fuel. The experimentally measured values of butanol blends in gasoline confirms that the properties of butanol are quite adaptive with gasoline which implies that no engine modifications required for using butanol blends with gasoline as a replacement to gasoline.
