Aquecedor resistivo de óleo diesel: aplicação em veículos rodoviários pesados

Abstract

Brazilian logistics is largely dependent on the road modal and, consequently, on diesel. Diesel oil marketed in the country does not have preparation to ensure quality at very low temperatures causing the appearance of paraffin crystals and clogging the filters of diesel oilpowered vehicles. The objective of this work is to develop an electronic fuel heating system from a resistance to avoid the formation of paraffin crystals. Low temperature tests were performed to monitor and understand the behavior of diesel in this respect. To control the heating, an Arduino and a temperature sensor were used, the power system is designed to be made by the vehicle's own batteries. In the tests, the heating was successful, proving what was scaled. For the installation and use of the prototype in a vehicle may need some adjustments due to the action of external agents, which may cause heat loss, not present in bench tests.
