Abstract
In Brazil, although the National Agency for Petroleum, Natural Gas and Biofuels (ANP) inspects the gas stations, there are still cases of adulteration in fuel. This can cause mechanical damages to car engines, incomplete combustion of fuels, and emission of oxidizing gases that are harmful to the environment and human health. The study aims to develop a device capable of identifying adulteration in fuels. To achieve that goal, five physicochemical parameters were studied: electrical conductivity, density, viscosity, refraction index, and pH; with the purpose to evaluate their sensibility to identify adulteration in anhydrous ethyl alcohol fuel (AEAF), commonly performed by the addition of water. In the research methodology, the volumetric percentage of 4,9% v/v of water in AEAF was used as a reference, since it is the maximum value allowed by law. Accordingly to the referential, lower equal and higher volumetric percentages were adopted: 3,2%, 4,9%, and 5,2% v/v of water were mixed with the AEAF. Posteriorly, a detector device with the ability to identify adulteration in fuels was developed. A programming code was written for the operation of an electro-resistive sensor that was transferred to an Arduino UNO R3 board after a successful simulation in the software Tinkercad. Essays were made in the Technology Laboratory of the Superior Institute of Engineering of Porto (ISEP) – Portugal and in the Minas Gerais Federal Institute (IFMG) – Brazil. The results of electrical conductivity of AEAF showed the following values: 180
