PERFORMANCE EVALUATION OF GASOLINE AND E50 FOR INTER COMBUSTION ENGINE

The present work represents the performance evaluation of Gasoline and E50 for the internal combustion (IC) engine. There is a lot of scope for performance evaluation to understand and adopt the various fuels for the internal combustion engine. In this work the various performance characteristics are analyzed for both the fuels. Then a comparison is made among both the fuels to understand the adoptability of these fuels. The first fuel used is 100% gasoline and the later one is 50% gasoline and 50% ethanol. In order to the performance of the engine with these fuels the emphasis is also made on compression ratio for these fuels. After the investigation it is observed that from gasoline to E50 the compression ratio is enhanced without any trouble of knocking. The investigation has resulted in two important results. First, E50 has shown a rise in power generation, engine torque and fuel consumption. Second a fall in emissions of nitrogen oxide, carbon monoxide and hydro carbon. Particularly at high compression ratio for the spark ignition engines E50 fuel gave a better performance than gasoline alone. The blending of gasoline with ethanol is a better choice for the IC engines.
