The significance of using a car deflector

The semi-trailer deflector, also known as the air deflector plate, can improve the aerodynamic performance of the vehicle and is an important measure to enhance the production efficiency of the vehicle, reduce fuel consumption and improve its performance. It is particularly important for special-purpose vehicles such as car trains and box semi-trailers that have a large windward area, high traveling speed and poor overall upward linearity. Therefore, most special-purpose vehicles and trains used on expressways are equipped with deflector covers.

With the development of automotive technology and highways, the speed of cars is increasing day by day. The aerodynamic resistance of cars interacting with air during driving is also becoming more and more significant, which to a large extent affects the economy, power performance and stability of cars. The numerical simulation of automotive aerodynamics is developing rapidly. By optimizing its aerodynamic performance, reducing the air resistance coefficient and improving fuel economy, considerable economic benefits can be generated. The body of a box truck is higher than the cab. This can reduce the air resistance coefficient. Therefore, it is even more necessary for box trucks to install deflector covers. The application of the deflector has contributed to green freight transportation and proposed new ideas and solutions for addressing the energy conservation and emission reduction challenges in the freight industry.
