Reduction of fuels by 15%

Engineers at the University of Delft (Netherlands) have developed a system of carenagens side for lorries, which reduces fuel consumption by up to 15%. The new solution aerodynamic tests showed the practical results higher than predicted by computer simulations on.
The set is composed of aerodynamic "skirts" side and a "tail" that reduces the so-called "track", a set of vacuum and air currents that exist in the rear of the trailer to the extent that the truck moves.
Based on the real tests, the researchers estimate that the investment in the placement of side skirts and tail of the truck is recovered in two years. The set aerodynamic as a whole reduced air resistance by 30%, which translates into a fuel economy of 15%.
