Higher octane number and clean burning ability of the renewable energy sources attracted the researchers as alternative for petrol. Many researchers have studied the effect of methanol and gasoline – methanol blends as fuel for spark ignition engine and showed better results for methanol in case of performance and exhaust emissions. The potential to use gasoline – methanol blends as fuel is due to improved performance and reduction in CO, CO2, UBHC and other pollutants. In this work, effect of spark timings on engine performance and emissions is studied at four different spark ignition combinations. The experimentation carried out on single cylinder four stroke twin spark ignition engine for both gasoline and methanol under full throttle condition at the fixed engine speed of 1600 RPM. The experimental results revealed that, fuel consumption increased for methanol compared to gasoline. However efficiency of the engine increased for methanol fuel due to the higher octane number and laminar speed of methanol with decrease in CO, CO2, UBHC and NOx.
