The research evaluates the impact that an aerodynamic device has on the diesel consumption of a medium-sized truck, by studying the drag force generated by the vehicle when it moves forward, the aerodynamic coefficient (drag) is considered, a Of the important variables that influence the reduction of this force, this coefficient has a dimensionless value of 0.78 in trucks according to international standards, with the use of several aerodynamic devices that can be incorporated in the different parts of the truck, so that the flow of air both outside and inside generate the least amount of restriction when traveling on the surfaces of the truck, this reduction would be achieved above, to assess the efficiency in fuel consumption, use DIN 70 030-2 through which a test protocol is developed, among the requirements of the standard is that the truck must travel 1 0 [km] at a constant speed of 90 [km / h], with a minimum of 4 repetitions and a maximum of 10, the diesel consumption was measured by gravimetry and with the Hino diagnostic equipment. The result of the investigation is a saving of 4.63 [%] in diesel consumption.
