The major issue faced today is the atmospheric pollution by the gases released by vehicles. 2-Methyl Furan (MF) is one such promising alternative that has potential to serve the purpose. The main objective of this experiment was to investigate the effects of adding MF in a four-stroke MPFI SI engine in terms of its performance, emission and combustion characteristics. Unleaded gasoline (UG) along with 3 concentrations of MF (M10, M20 and M30) blended with UG were used as test fuels. The tests were conducted at a constant load of 20 N m with the speed ranging from 1400 to 2800 rpm with an increment of 200 rpm. When the blend percentage increased there was a decrease in CO and HC emissions with an increase in the BTE and NOx emissions. The curve for the pressure and the maximum rate of heat release shifted towards left reducing the ignition delay with the addition of blends. When the ignition timing was retarded slightly by 2 degrees Crank Angle (CA) to counter the NOx, the BTE and NOx emissions were comparatively lesser as expected. On the other hand, CO and HC emissions showed a gradual rise and maximum value of peak pressure and heat release occurred little later. (C) 2016 Faculty of Engineering, Alexandria University.
