Evaluación de un motor OTTO experimental de baja cilindrada bajo diferentes porcentajes de mezcla gasolina-etanol a 2850 MSNM

Abstract

Global warming and energy security as global issues have shifted researchers' focus to renewable energy sources that could partially or fully replace petroleum products. Ethanol and butanol are renewable sources of energy that can be produced by fermenting biomass. Much research has already been done to develop suitable blends of ethanol and gasoline. The general objective of this work was to evaluate the mechanical and environmental behavior of an experimental low-displacement engine at 2850 meters above sea level by means of experimental tests for the issuance of criteria on its operation with gasoline-ethanol mixtures. The experiments were carried out in an experimental single-cylinder 4-stroke ignition engine with air cooling. The experiments involved the measurement of emissions, specific fuel consumption and power, through the instrumentation of the engine test bench and gas analyzer calibrated by national standards. It was concluded that there is a significant difference between the gasolines experienced in relation to consumption, with Super+E15, Extra+E15, and Super+E5 being the ones with the best results for the power developed. On the other hand, there was a significant difference between the gasolines, with Super+E15 and Extra+E15 being the ones with the best results for specific fuel consumption in this analysis.
