Evaluation of Methanol Gasoline Fuel Blends and Exhaust Emission of Single Cylinder Spark Ignition Engine

There are great concerns, that the IC Engines are responsible for extreme atmospheric pollution. Therefore, the studies on use of alcohols in 4-Stroke spark ignition (SI) Engines are important. In this study, the properties of the blended fuels were calculated. The effect of methanol-gasoline blends on emissions was investigated experimentally. The emissions were measured with the use of methanol-gasoline blends (M5 and M10) have been compared with the pure gasoline. The test was conducted at the constant speed of 90 km/h and at different wheel powers. From the analysis, it was concluded that when the engine was fuelled on methanol gasoline blends, CO2, CO, HC and NOx vehicular emissions were found to decreased at all wheel powers at 90 km/h. In addition, air-fuel ratio also increased with the increase percentage of methanol in the gasoline.
