Not only the reason of the engine, but also with the vehicle's wind resistance coefficient is also a great relationship. Many imported cars have adopted the installation of diversion parts
to reduce the wind resistance of the vehicle in the process of driving, so as to reduce the engine, so as to achieve the purpose of fuel saving. Do not look down upon this diversion component,
but the aerodynamic basis, the fuel saving effect is quite good! On heavy trucks, the vehicle's flow guide assembly is usually the roof guide hood, side guide plate, side skirt plate, guide groove,
sun visor and guide groove. This time we will focus on the top guide hood and the side guide plate.
