The effect of methanol-gasoline blends on the engine performance and combustion characteristics have been investigated experimentally. In this work a 4-storke cylinder digital twin spark ignition engine is used. The tests were performed at different loads for blends such as M10, M15, M20, M25, M30, as well as for pure gasoline also at 32°BTDC for one spark plug and 28°BTDC for the other one. The results shows improvement in physical properties by adding methanol since methanol is volatile than gasoline. The experimental results revealed that the fuel consumption and brake thermal efficiency is increased by increasing methanol content in blends. The emission results shows decrease in CO, UBHC, NOx. © Research India Publications.
