Determination of torque and power of internal combustion engine using gasoline magna, ethanol blend with gasoline magna and E85 biogasol

The present research focuses on the study of the power generated in a 105 hp four-stroke in-line reciprocating internal combustion engine (MCIA) using three different renewable and non-renewable fuels: E85 biogasol and gasoline-oxyfuel. The power and torque generated with the blends were compared for the three fuels. The device used to measure torque and power was a dynamometer based on the prony brake principle. According to the results obtained, the power and torque generated using E85 biogasol are 16% lower than those generated using 100% gasoline. This is due to the fact that in the case of renewable fuels, the lower powers obtained were generated by the use of a poor mixture in the combustion chamber of the engine due to lack of calibration of the fuel map. In the case of the magna gasoline-oxyfuel blend, a torque value similar to that of the magna gasoline was obtained but at lower rpm, this effect indicates an advantage for the implementation of renewable fuels in a MCIA.
