In this article, a study is carried out in a city of 50 m. Above sea level, on the volumetric expansion of 87 and 92-octane gasoline and diesel fuel (named: Ecopais, Super, and Diesel) inside the tanks. The aim is to determine the volume variations due to temperature changes. The justification is based on the lack of specific information on the subject. The proposed methodology includes a mathematical model supported by thermographic analysis experiments to visualize the dilatation of fuels. A volume variation of up to 0.55% was evidenced in the fuel tanks as a result of ambient temperature fluctuations. However, the use of thermographic tools as a measurement method does not facilitate the detection of this volumetric variation in the tanks; it depends on the volume and camera capacities. Using Pearson’s index shows that the correlation is direct, and the influence of temperature affects the perception of volume.

摘要

In this article, a study is carried out in a city of 50 m. Above sea level, on the volumetric expansion of 87 and 92-octane gasoline and diesel fuel (named: Ecopais, Super, and Diesel) inside the tanks. The aim is to determine the volume variations due to temperature changes. The justification is based on the lack of specific information on the subject. The proposed methodology includes a mathematical model supported by thermographic analysis experiments to visualize the dilatation of fuels. A volume variation of up to 0.55% was evidenced in the fuel tanks as a result of ambient temperature fluctuations. However, the use of thermographic tools as a measurement method does not facilitate the detection of this volumetric variation in the tanks; it depends on the volume and camera capacities. Using Pearson’s index shows that the correlation is direct, and the influence of temperature affects the perception of volume.
