Across the world, methanol is evolving as a clean, sustainable transportation fuel for the future. Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol's high octane and oxygen content produces a cleaner burning gasoline which significantly reduces vehicle exhaust emissions. A lower boiling temperature for better fuel vaporization in cold engines, the highest H-C ratio for a lower carbon intensity fuel, and no Sulphur contamination which improves catalytic converter operation. In the paper, a study is carried out for the blend of 15% methanol (M15) with Gasoline on BS-IV vehicles and a comparison is done for the tailpipe emissions. A gap analysis of vehicles with E0 and M15 fuel is done with baseline emission testing along with full throttle performance of the vehicle to check the effect of oxygenated fuel (M15). The main purpose of this study is to analyze the impact of M-15 fuel on 2 and 3-wheeler vehicles in the as-is condition without any engine tuning and retaining the base gasoline (E0) settings.
