Abstract
Some concerns regarding the depletion of non-renewable sources of energy along with the environmental damage resulting from their use have motivated the search for alternative fuels. Ethanol is a renewable and important energy alternative for Otto-cycle engines. In such context, this study proposes the evaluation of carbon monoxide (CO) and total hydrocarbons (THC) concentrations and the performance of a spark-ignited non-road engine fueled with gasoline types A and C (GC, with 27% ethanol) and kerosene as adulterant in different proportions. Quality parameters of the fuel blends were also evaluated. The results revealed some difficulties in the identification of gasoline adulteration, relating to the current legal parameters in the conditions of mixtures and tests used in the study. Regarding the gaseous emissions, the addition of the adulterant resulted in an increase of the CO and THC concentrations to 74% and 78%, respectively, in gasoline type C with 30% adulterant, when compared to gasoline C free of adulterant. The addition of ethanol to the gasoline resulted in a reduction of the CO and THC concentrations to 64% and 56%, respectively, in relation to the pure gasoline (without ethanol), evidencing greater combustion efficiency due to the presence of the oxygenated fuel (ethanol).
